Adamellite and Theralite

Adamellite

Theralite

Definition

Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz

Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline

Formation

Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.

Theralite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
