Basaltic Trachyandesite and Amphibolite


Amphibolite and Basaltic Trachyandesite


Definition

Definition
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface   
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.   
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
