Chlorite, a green colour mineral is mainly derived from the decomposition of A. Augite B. Biotite C. Hornblende D. All of these

Augite
Biotite
Hornblende
All of these

The correct answer is D. All of these.

Chlorite is a green-colored mineral that is mainly derived from the decomposition of augite, biotite, and hornblende. It is a member of the phyllosilicate group of minerals, which are sheet silicates. Chlorite is a common mineral in metamorphic and igneous rocks. It is also found in some sedimentary rocks.

Augite is a dark green or black mineral that is found in mafic and ultramafic igneous rocks. It is a member of the pyroxene group of minerals. Augite is a common mineral in basalt, gabbro, and peridotite.

Biotite is a black or dark brown mineral that is found in igneous and metamorphic rocks. It is a member of the mica group of minerals. Biotite is a common mineral in granite, gneiss, and amphibolite.

Hornblende is a dark green or black mineral that is found in mafic and ultramafic igneous rocks. It is a member of the amphibole group of minerals. Hornblende is a common mineral in basalt, gabbro, and peridotite.

When augite, biotite, and hornblende decompose, they form chlorite. Chlorite is a common mineral in metamorphic rocks that are formed from mafic and ultramafic igneous rocks. It is also found in some sedimentary rocks that are formed from the weathering of mafic and ultramafic igneous rocks.
