WebThe differences between the composition of lava and magma. It is fairly hard to describe the differences of these two products of volcanic process. ... Types of magma are determined by chemical composition of the magma. Three general types are recognized: 1.Basaltic magma -- SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na WebApr 1, 2024 · Geology. There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition. All types of magma have a significant percentage of silicon dioxide. Basaltic magma is high in iron, magnesium, and calcium but low in potassium and sodium.
WebSep 3, 2024 · The words that describe composition of igneous rocks also describe magma composition. Mafic magmas are low in silica and contain more dark, magnesium and iron rich mafic minerals, such as olivine and pyroxene. Felsic magmas are higher in silica and contain lighter colored minerals such as quartz and orthoclase feldspar. WebFeb 8, 2024 · 7. Describe how the speed of magma/lava cooling (slow/fast) affects the size of mineral crystals (large/small). __ _____ the size of the crystals depends on how quickly the molten magma solidified: magma that cools slowly will form an igneous rock with large crystals. lava that cools quickly will form an igneous rock with small crystals. What …

WebMafic magmas have 45% to 55% SiO 2, about 25% total of FeO and MgO plus CaO, and about 5% Na 2 O + K 2 O. Felsic magmas, on the other hand, have much more SiO 2 (65% to 75%) and Na 2 O + K 2 O (around … theory zipper dressMagma consists of liquid rock that usually contains suspended solid crystals. As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near the surface consists of materials in solid, liquid, and gas phases. Most magma is rich in silica.
