Magma <\/strong>is molten rock below the surface. Lava <\/strong>is molten rock that is now exposed at the surface. Igneous rocks<\/strong> are rocks that form from the solidification of magmas. (All igneous rocks were once molten.)<\/span><\/span><\/p>\n\n
\n
Generating magmas<\/span><\/span><\/strong><\/p>\n\n
Most magmas form at great depth when mantle rock partially melts. We call the composition of mantle rock ultramafic<\/strong>, which means it's silica content is lower than typical crustal rocks and it's also high in magnesium and iron. This ultramafic mantle rock is solid under its usual pressure and temperature conditions. Its minerals are stable in solid form (like food in an icebox). To melt mantle rock, there must be a change in the normal conditions. If temperature increases for example, some of the minerals in the mantle rock will start to melt (not all, just some \u2013 think of increasing the temperature in your freezer \u2013 not everything starts to melt at once). If pressure decreases or water is added (or both), the melting point of a mineral actually decreases and it will start to melt. As small amounts of melt migrate and accumulate, they form a magma.<\/span><\/span><\/p>\n\n
Imagine taking a jar and filling it with marshmallows, water, and syrup. Now freeze it. The composition of the jar is the combined composition of all three ingredients. But if you increase the temperature of the jar slightly, so that some components are still frozen and others not, (say the water melts only), then you get a melt forming that has a different overall composition from the jar\u2019s materials. The original composition was marshmallows, water, and syrup. The melt that forms from a slight increase in temperature is pure water. The residual material left behind is marshmallows and syrup (no water). <\/span><\/span><\/p>\n\n
The same thing happens in the mantle. When ultramafic mantle rock begins to melt, only minerals with the lowest melting temperatures go into the magma phase. Others remain behind. We call this partial melting<\/strong>. We can study the composition of mantle rocks and tell if they\u2019ve produced melts before. (If our jar contains only marshmallows and syrup, then we know it partially melted and lost its water.) <\/span><\/span><\/p>\n\n
To melt mantle rock, there must be a drop in pressure (which is what happens under oceanic ridges where seafloor spreading occurs), a rise in temperature (which is what happens when plumes migrate from the deep in the Earth, through the mantle and the crust), or an influx of water (which happens where subduction zones reinject water-rich oceanic crust back into the mantle). <\/span><\/span><\/p>\n\n
Partially melted mantle tends to produce mafic compositions. Fully melted mantle produces ultramafic magmas. After these magmas are produced at depth, they rise because of buoyancy.<\/span><\/span><\/p>\n"},"library":"H5P.AdvancedText 1.1","metadata":{"contentType":"Text","license":"U","title":"Untitled Text"},"subContentId":"4d962ee5-ee33-46e6-8867-9c89dec4510b"},"useSeparator":"auto"},{"content":{"params":{"text":"

Changing magma composition<\/span><\/span><\/strong><\/p>\n\n
As magmas rise from the mantle where they formed towards the surface, they can mix with other magmas (magma mixing<\/strong>) or melt rocks that they are moving through (assimilation<\/strong>), both of which processes will change magma composition. In addition, as magmas rise to the surface, they gradually cool down. When magmas cool, crystals start to form. If, after a mineral forms, it is removed from the magma through gravitational settling or floating or other processes, the magma composition will change. We call this process crystal fractionation<\/strong>.<\/span><\/span><\/p>\n\n
Occasionally magmas carry pieces of foreign rocks that are caught up in the magma when it moves through and breaks surrounding rock. Such foreign rocks are called xenoliths<\/strong>. <\/span><\/span><\/p>\n\n
Magma chambers <\/strong>are areas in the crust where magmas accumulate and reside for long periods of time. Magmas in these chambers can erupt at any time \u2013 usually when new magmas rise under them and push them out. Since magma compositions can change so easily over time through the methods described above, the composition of erupted lavas or plutons (bodies of rock that crystallized from magmas that stayed underground) from a single volcano can also vary. <\/span><\/span><\/p>\n"},"library":"H5P.AdvancedText 1.1","metadata":{"contentType":"Text","license":"U","title":"Untitled Text"},"subContentId":"047b23cc-07e7-419e-94f9-174f165523d0"},"useSeparator":"auto"}]},"library":"H5P.Column 1.18","subContentId":"3f849326-e703-4be8-a530-1ac376a6c03e","metadata":{"contentType":"Column","license":"U","title":"Magma Generation and Migration"}},{"params":{"content":[{"content":{"params":{"text":"

Magma composition changes through crystal fractionation<\/strong> when particular elements are removed to form early minerals. Most early minerals, like olivine, plagioclase and pyroxene, contain high amounts of (iron) Fe, (magnesium) Mg, and (calcium) Ca, and lower amounts of silicon than other silicate minerals. Thus, early crystal fractionation removes iron, magnesium, and calcium from the magma, leaving the magma preferentially enriched in silicon and sodium. <\/span><\/span><\/p>\n\n

Bowen\u2019s Reaction Series: <\/strong>the order in which crystals form as a magma that forms from melting the mantle rises through the crust and cools. <\/span><\/em><\/p>\n\n
Bowen's Reaction Series <\/strong>describes the sequence of minerals that are formed as a magma produced by melting the mantle (ultramafic in composition) rises through the crust, cools, and experiences crystal fractionation. Remember that crystal fractionation causes magma composition to change or \"evolve\" as the earliest-formed minerals are removed. <\/p>\n\n
\n\t
The right side of the diagram shows temperature cooling as the magmas rise.<\/li>\n\t
The left side shows the compositions that match the different levels of magma evolution (most primitive at bottom and most evolved at top). Note: these also correspond to silica content -- because as the magmas evolve, the silica content of the magma increases.<\/li>\n\t
The center shows the minerals that would crystallize at those temperatures when the magma has evolved to that particular composition (silica content). Where an arrow appears (any part of that arrow), that means that mineral can show up in that composition and with the other minerals you see overlapping it. Note: The top 3 minerals have no arrows. According to this model, those 3 minerals will appear in all felsic rocks.<\/li>\n<\/ul>\n\n
The best way to read this diagram is to draw a horizontal line through it at any point (horizontal lines are those that run from one side to the other of the diagram)<\/em>. Imagine that line to be a rock that formed from a magma that made it to this point in the series (either by erupting or by preventing the loss of any minerals -- stopping crystal fractionation -- and cooling completely underground).<\/p>\n\n
\n\t
Any mineral arrows that your horizontal line intersects will appear together in that rock.<\/li>\n\t
The composition that your line intersects is the composition name given to the rock. <\/li>\n<\/ul>\n\n
As you can see, primitive <\/strong>magmas (ultramafic) are composed of olivine, plagioclase, and pyroxene. <\/span><\/span><\/p>\n\n
Any rock that is formed from the most evolved <\/strong>composition (felsic) contains, for sure, the three minerals listed (the ones with no arrows), and might also contain those of the three arrows that enter just at the bottom of that composition.<\/p>\n\n
Notice that, according to Bowen's Reaction Series, plagioclase feldspar<\/strong> forms throughout all compositions. Its composition changes from more calcium rich in the ultramafic and mafic magmas to more sodium rich in the more evolved magmas. <\/span><\/span><\/p>\n"},"library":"H5P.AdvancedText 1.1","metadata":{"contentType":"Text","license":"U","title":"Untitled Text"},"subContentId":"e2a6359d-4436-43b5-af6e-9897c6119ab4"},"useSeparator":"auto"},{"content":{"params":{"introPage":{"showIntroPage":false,"startButtonText":"Start Quiz","introduction":""},"progressType":"dots","passPercentage":100,"questions":[{"params":{"scoreShow":"Check","submit":"Submit","tryAgain":"Retry","scoreExplanation":"Correct answers give +1 point.

\n
Volcanic (or extrusive) igneous rocks<\/span><\/span><\/strong><\/p>\n\n
Magmas that reach the surface and erupt as lavas ultimately form extrusive <\/strong>rocks. We classify extrusive rocks by the eruption style and the composition of the magmas. Basalts <\/strong>are the products of mafic lavas. Rhyolites <\/strong>are the products of felsic lavas. Andesites <\/strong>are intermediate. (Note: Ultramafic lavas don\u2019t exist on Earth anymore, as our crust it too thick, even in the oceans, to allow no evolution to occur during magma transit). When lavas erupt at the surface, they cool too quickly for visible crystals to form (though there are crystals in the rocks, just too small to see). We call the texture of these rocks aphanitic <\/strong>(most crystals are too small to see). Note: <\/span><\/span><\/p>\n\n
Any large crystals found in volcanic rocks were produced at depth in the magma chamber (imagine a few minerals just beginning to slowly form throughout the magma \u2013 they\u2019d be scattered, like poppy seeds in a muffin). These crystals are carried to the surface during the eruption. Volcanic rocks that consist of an aphanitic (or small-crystal size) matrix or groundmass <\/strong>with larger crystals disseminated throughout that groundmass, like chocolate chips in a cookie are called porphyritic<\/strong>. Sticking with the chocolate chip cookie analogy, the chips are called phenocrysts<\/strong>; they formed when the magma was still underground (prior to eruption); the rest of the cookie is the groundmass; it formed after eruption. Most volcanic rocks display a porphyritic texture in some form. We name such rocks by preceding the name with the major phenocryst and ending the name with the word, porphyry. Example: olivine basalt porphyry.<\/span><\/span><\/p>\n\n
The more evolved the magma (felsic), the more silica, and hence the more viscous the fluid. (Viscosity is a measurement of a fluid\u2019s resistance to flow: syrup is more viscous than water.) As viscosity increases, it becomes harder to produce crystals (ions have a hard time moving through the melt to find each other). Occasionally, extremely evolved magmas produce lavas that are so viscous that they cool before they can produce any crystals. When no crystals form, we call the substance glass<\/strong>. Felsic lavas that cool as glass are called obsidian<\/strong>. Glass usually forms when lavas either cool too quickly to form crystals, or when the lava is so viscous that ions can\u2019t move to form crystals.<\/span><\/span><\/p>\n\n
Magmas also can contain a lot of gas (water, sulfur dioxide, carbon dioxide, etc.). When such lavas erupt, a process occurs that is similar to opening the top on a can of shaken soda. The gas immediately wants to get out of the lava. As lavas flow across the surface, these gases rise through the lava. When the lava cools and solidifies around gases, the final rock contains vesicles<\/strong>, small round pockets in the rock, where gas was trapped while moving.<\/span><\/span><\/p>\n\n
When erupted lavas contain more vesicles than rock, they have a frothy <\/strong>texture (lightweight \u2013 mostly holes \u2013 with the actual rock made of glass \u2013 no minerals \u2013 quickly cooled). Frothy rocks are called pumice <\/strong>if they\u2019re light colored (and therefore felsic or intermediate in composition) or scoria <\/strong>if they\u2019re dark colored (and therefore mafic in composition). Because mafic compositions have iron in them, scoria is not light enough to float in water. Pumice, however, does!<\/span><\/span><\/p>\n\n
Lavas that contain more gas than liquid will erupt violently as ash. Ash<\/strong> is just a tiny drop of liquid that adheres to the exsolving gas bubbles and solidifies into glass (no crystals) as soon as it hits the air. Ash (as well as particles pumice, crystals, and other volcanically ejected material \u2013 collectively called pyroclastic<\/strong> debris) can accumulate on the surface of volcanoes. When this material is compressed or welded together, it forms a rock called Tuff<\/strong>. Pyroclastic rocks are made of pieces (clasts) of material that came from a volcano or fire (pyro).<\/span><\/span><\/p>\n"},"library":"H5P.AdvancedText 1.1","metadata":{"contentType":"Text","license":"U","title":"Untitled Text"},"subContentId":"eb1887be-227b-4e32-b3eb-aeceb8439d8b"},"useSeparator":"auto"},{"content":{"params":{"decorative":false,"contentName":"Image","file":{"path":"images\/file-632ddef417c45.JPG","mime":"image\/jpeg","copyright":{"license":"U"},"width":1308,"height":872},"alt":"Panum crater obsidian","expandImage":"Expand Image","minimizeImage":"Minimize Image"},"library":"H5P.Image 1.1","metadata":{"contentType":"Image","license":"U","title":"Untitled Image"},"subContentId":"a40b93bf-598d-46ba-b36f-13229a68280d"},"useSeparator":"auto"},{"content":{"params":{"text":"

Plutonic (or intrusive) igneous rocks<\/span><\/span><\/strong><\/p>\n\n
Magmas that never reach the surface will cool at depth in a magma chamber or vein or dike. As long as they are deep, they cool slowly and form large crystals (crystal size increases with slower cooling). Slowly cooling mafic magmas produce gabbro <\/strong>(the plutonic equivalent of a basalt). Slowly cooling felsic magmas produce granite <\/strong>(the plutonic equivalent of rhyolite). Intermediate magmas produce diorite <\/strong>(the plutonic equivalent of andesite) . We call the texture of these larger-crystalline rocks phaneritic <\/strong>(100% crystals visible to the eye).<\/span><\/span><\/p>\n\n
We attach the term pegmatite <\/strong>to any plutonic rocks with unusually large crystals. Pegmatites form because cooling was slow and water content was extremely high, thereby decreasing magma viscosity and allowing ions to migrate quickly. To name such rocks, we append the word, pegmatite, to the end of the rock name.

All igneous rocks can be classified as one of the following textures<\/strong>:<\/p>\n\n
\n\t
Phaneritic<\/strong>: 100% crystals visible to naked eye (might have unusually large crystals -- see Pegmatitic subcategory below)<\/li>\n\t
Aphanitic<\/strong>: Most crystals are too small to see with naked eye (might have some large crystals scattered throughout -- see Porphyritic subcategory below)<\/li>\n\t
Glassy <\/strong>-- 100% glass<\/li>\n\t
Frothy<\/strong> -- Greater than 50% of rock is vesicles; rest is glass<\/li>\n\t
Pyroclastic <\/strong>-- Made of fragments of ash, crystals, pumice, and rocks, all thrown from erupting volcano and gatehred together.<\/li>\n<\/ul>\n\n
\n
**PEGMATITES are a subcategory of phaneritic texture<\/span>
\nPEGMATITE (noun) or PEGMATITIC (adjective)<\/span><\/strong>
\nAdd PEGMATITE to the name IF the rock displays pegmatitic texture: If an intrusive igneous rock has extremely large minerals (> 2 inches long), the rock is called a pegmatite. <\/span><\/span><\/p>\n\n
\n\t
Naming examples: granite pegmatite<\/span><\/span><\/li>\n<\/ul>\n\n
\n
**PORPHYRY is a subcategory of aphanitic texture<\/span>
\nPORPHYRY (noun) or PORPHYRITIC (adjective)<\/span><\/strong>
\nAdd PORPHYRY to the name IF the rock displays porphyritic texture. If an aphanitic igneous rock has phenocrysts in it (large minerals surrounded by an aphanitic matrix), it is called porphyritic. Add the name of the prominent phenocryst mineral to the front of the rock name. <\/span><\/span><\/p>\n\n
\n\t
Naming example: olivine basalt porphyry<\/span><\/span><\/li>\n<\/ul>\n\n
** Porphyritic rocks can rarely be found in the Phaneritic category as well, where 100% of the crystals are visible, but some formed first and grew larger than the others. For purposes of this class, however, all porphyritic rocks we will see will be aphanitic (background mass of crystals are too small to see).<\/span><\/span><\/em><\/p>\n\n

Igneous Rock Characterization and Identification<\/span><\/span><\/strong><\/p>\n\n
To identify (name) igneous rocks, you determine two things about the rock: composition <\/strong>and texture<\/strong>. <\/span><\/span><\/p>\n\n
\n\t
First determine composition, which is based on mineral content or color, if you can\u2019t see minerals. The rows in the table below are the four compositions: ultramafic, mafic, intermediate and felsic<\/span><\/span><\/li>\n\t
Then determine the texture of the rock: phaneritic, aphanitic, glassy, frothy, or pyroclastic. The columns in the table below are the texture options.<\/span><\/span><\/li>\n\t
Find the cell in the table below that matches the composition and texture, and you will have the rock name.<\/span><\/span><\/li>\n\t
