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
WebbA few rock specimens are distinguished by low 143Nd/144Nd values suggesting assimilation and mixing of much older crustal material. Despite their similar whole-rock chemical compositions, the postglacial rhyolitic extrusives differ from the felsic xenoliths by their glass composition and the absence of amphibole. WebbLava Flows - Sometimes lava races down the side of a volcano like a fast moving, incandescent stream, sometimes it builds into a rubble-covered mound at a volcano’s summit, and sometimes it oozes like a sticky but scalding paste into blob-like masses - Clearly, not all lava behaves in the same way when it rises out of a volcano so not all lava …
WebbRhyolite: This is a rock with more than 68% silica. They are composed mostly of quartz and alkali feldspars, but they can also contain minerals such as zircon, tourmaline, and biotite. Because of their high silica content, rhyolite lava usually forms lava domes and mesa lavas. WebbThe specific heat capacity of Granite is 0.79 kJ/Kg K and that of Rhyolite is Not Available.
