This mixture is usually made up of four parts: a hot liquid base, called … WebExtrusive igneous rocks are the products of volcanic activity. They appear at the surface as molten lava that spreads in sheets and hardens, or they are made up of fragments of magma ejected from vents by violent gaseous explosions. Large-scale extrusive features include stratovolcanoes (composite cones), shield volcanoes, lava domes, and ...
WebApr 6, 2016 · Explanation: The change from granite to gneiss is not mineralogical (i.e. there are no chemical changes) but structural. Another important structural change is the development of foliation or linear appearance in a gneiss. This is due to the long minerals in the original granite lining up perpendicular to a regional stress field. WebAnswer (1 of 2): Only indirectly. First you have to strongly weather the granite to form quartz and clays. Then you need to erode this material and separate out the quartz sand. Next you bury this sand deep under several km of other sediments until it firstly turns into sandstone. Under even deep...
