gabbro

Geo. ගැබ්‍රෝව

Definition:

Noun: A dark-colored, coarse-grained igneous rock composed mainly of calcium-rich plagioclase feldspar, augite, and sometimes olivine, known for its slow cooling process deep within the Earth's crust.

Gabbro is typically found in large intrusions such as batholiths and is commonly used in construction and as a dimension stone. It is characterized by its color range of dark greens to blacks, with occasional lighter minerals.

Gabbro is a prevalent rock in oceanic crust and is often associated with the formation of oceanic crust at mid-ocean ridges.
