What is the chemical formula for Gabbro?

Answer 1

Gabbro rock is in the same family as Basalt rock and there for has similar chemical composition. Basalt is nearly half composed of silica and has other minerals in much smaller percentages such as titanium dioxide, iron oxide, aluminum and magnesium.

Answer 2

The chemical formula for gabbro is based on its mineral composition, which typically includes plagioclase feldspar, pyroxene, and olivine. The general formula can be expressed as (Ca,Na)[Al,Fe^3+,Ti]^2[Si,Al]^2O8 + Fe^2+Mg^2+2Si2O6.

Answer 3

Pyroxene, plagioclase feldspar, amphibole, and olivine.

Answer 4

Gabbro contains approximately sixty percent pyroxene, twenty-five percent plagioclase, twelve percent olivine, and three percent amphibole.

Answer 5

Only the minerals from gabbro have a specified crystalline structure.
