Gabbro - an overview | ScienceDirect Topics

The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite. A thick bed of kaolinite, goethite and some gibbsite underlies the bauxite.

Gabbro - Igneous rocks

Gabbro is a coarse-grained and usually dark-colored igneous rock.It is an intrusive rock. It means that it formed as magma cooled slowly in the crust. Igneous rocks with similar composition are basalt (extrusive equivalent of gabbro) and diabase (the same rock type could be named dolerite or microgabbro instead).. Gabbro with large augite phenocrysts embedded in white plagioclase.
