What is gabbro aggregate?

Answer 1

Gabbro refers to a large group of dark, coarse-grained, intrusive mafic igneous rocks chemically equivalent to basalt. The rocks are plutonic, formed when molten magma is trapped beneath the Earth's surface and cools into a crystalline mass.

An aggregate in civil engineering terms is a series of coarse clastic or particulate materials which are used in construction.

To form aggregate from Gabbro, it is typically extracted from a quarry by blasting and then crushed to the required size.

Answer 2

Gabbro is an intrusive igneous rock, the chemical equivalent of basalt, an extrusive igneous rock. Gabbro is black to green and high in magnesium and iron.
