3 • Dissolved Gases • Gas content affects magma mobility • Gases expand within a magma as it nears the Earth’s surface due to decreasing pressure • The violence of an eruption is related to how easily gases escape from magma To Summarize: • Fluid basaltic lavas generally produce quiet eruptions • Highly viscous lavas (rhyolite or andesite) produce more explosive eruptions At divergent boundaries and oceanic mantle plumes, where there is little interaction with crustal materials the magma tends to be consistently mafic. There are three major types of magma based on its mineral content: Basaltic Magma has a low silica content Basalt Basaltic Magma Associated with volcanoes in Hawaii. Basic Types of Magma Andesitic Magma. 3 Types of Magma - Wikispaces was published by on 2015-06-12. Magmas derived from crustal material are dominated by oxygen, silicon, aluminum, sodium, and potassium. Types of Magma. The remaining elements make up the other one-quarter. Magma (from Ancient Greek μάγμα (mágma) meaning "thick unguent") is the molten or semi-molten natural material from which all igneous rocks are formed. 0000007486 00000 n Magmas can vary widely in composition, but in general they are made up of only eight elements; in order of importance: oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium (Figure 3.6). Andesitic magma-- SiO2 55-65 wt%, intermediate. 0000002039 00000 n The classification of the Magmas is done primarily on the basis of Silica content. trailer Types of Magmas 6. zVolcanicor extrusiveigneous rocks form when the magma cools and crystallizes on the surface of the Earth. 36 21 The type of lava will determine both the explosiveness of its entry to the surface (force of eruption) and its flow. For example, basaltic magma contains more iron and magnesium than granitic magma, but granitic magma is richer in silicon, potassium, and sodium. Types of magma are determined by chemical composition of the magma. The term rhyolitic is used to describe the magma that solidifies to form granite because magmas are named after extrusive rocks. Among major elements, the ratio between alkalis and silica has a key role in determining the type of magma series: silica- saturated basaltic magmas evolve to rhyolites, alkali basalts differentiate to trachytes, and undersaturated basaltic magmas (basanites, foidites) form phonolites. Lava’s temperature usually ranges between 1300 and 2200 degrees F. The temperature of magma usually ranges between 1300 and 2400 F. Lava cools much faster than magma, which may lead to part of the melt being unable to crystallize and thus becoming glass. 0000001568 00000 n Three general types are recognized: Basaltic magma -- SiO 2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na Print a read and math workbook with Types of Magma reading comprehension. 0000001632 00000 n extrusive rock Basalt Andesite Rhyolite melting temperature >1000oC 900oC 800oC dissolved gas little lots lots Volcanic Eruptions •Distinguish between nonexplosive and explosive volcanic eruptions. • Identify the features of a volcano. MAGMA 2.18 The name ‘MAGMA’ comes from Bourbaki (and Serre) where it is used to denote a set with one or more binary operations without any additional axioms. Unlike some of the other types of volcanoes—namely, shield volcanoes and composite volcanoes—cinder cones are usually created from a … 4.2 Magma Composition and Eruption Style As noted in the previous section, the types of magma produced in the various volcanic settings can differ significantly. The rest of the magma will then have a different composition than the original magma (for example it will have less iron and magnesium), and if some magma is then forced out of the magma chamber (into a dyke or as a volcanic eruption) it will produce rocks of different composition than the original magma. 56 0 obj<>stream After doing this, one of two things will happen: either the screen will display something like Magma V2.13-15 Wed Jan 2 2008 20:09:11 on crazylegs-crane [Seed = 255043391] Type ?

Rocks are naturally occurring combinations of fossils and other hard materials. Today, in 2012, Version 2.18 of MAGMA is a huge system with more than 5000 pages of documentation in 13 volumes. ��& i�ۂ�)$�?���$"�U�'�f�Mv"(�l�e�I�T�ڨ>�t�D�Qk�4�Eqo@;� Felsic magma is made up of 65 to 75 percent silica. • Derivative magma: Derivative magmas are the magma which derived directly from a preexisting magma. The rock cycle starts with magma. S. Adam Soule, in The Encyclopedia of Volcanoes (Second Edition), 2015. Magma generation beneath MORs occurs through decompression melting of upwelling mantle in response to plate separation. startxref in Fe, Mg, Ca, Na, K 3. Increasing silica content is the basis of classifying the Magma from Picritic to Felsic. Magma Types Mafic Intermediate Felsic (basaltic) (andesitic) (rhyolitic) SiO2 Content 45-52% 53-65% > 65% typ. All rocks go through the rock cycle and recycle. Volcanoes – different origins of magma • The two major types of volcano have different types of magma production • This results in different magma composition • Magma composition affects eruption style (USGS, public domain) (H Grobe/ AWI 2007, Less dangerous compared to other types, cinder cones only grow to about 1,000-1,200 feet tall. 0000001220 00000 n 2.

Volcano - Volcano - Six types of eruptions: Volcanoes are frequently classified by their size and shape (as is described in the section Volcanic landforms), but they can also be classified by their eruptive habits. Magma Types and Eruptions. 0000004673 00000 n Thus a magma is the most basic of algebraic structures. Therefore, the composition of magma differs in each of these settings. Magma is the name given to molten rock while it’s still under the Earth’s surface. The process of magma formation is different at each type of plate boundary, where the tectonic setting is unique. It usually consists of silicate liquid, although carbonate and sulfide melts occur as well. View typesofrocks.pdf from EARTH SCI 1101 at Bernardo College.
