gabbroisch
Gabbroisch is a geological term used to describe rocks that have gabbroic characteristics. In English, the corresponding adjective is gabbroic. It refers to coarse‑grained, mafic intrusive rocks whose mineral assemblage and texture resemble the mineralogy of gabbro.
Mineralogy and texture typically define gabbroisch rocks. The dominant minerals are calcic plagioclase feldspar and pyroxene,
Formation and relation to basalt describe the origin of gabbroisch rocks. They crystallize from mafic magma
Occurrence and classification place gabbroisch rocks in various geological contexts. They are common in oceanic crust
In summary, gabbroisch describes coarse, gabbro-like rocks formed by slow underground crystallization of mafic magma, the
