Gabbro

Posted on February 1, 2011 by Cameron Speirs

Course-grained, intrusive, igneous rock that contains greater proportions of dark minerals than granite, and is typically grey, brown or black in colour. Gabbro is exceptionally rough to the touch due to highly erosion-resistant feldspar crystal standing proud of the rock surface.
