Solution(By Examveda Team)

Chlorites are a group of phyllosilicate minerals common in low-grade metamorphic rocks and altered igneous rocks.
Chlorite belongs to the 2 : 2 type. The typical general formula for chlorite is (Mg, Fe)₃(Si, Al)₄O₁₀(OH)₂ · (Mg, Fe)₃(OH)₆. This formula emphasizes the structure of the group, which is described as TOT-O and consists of alternating TOT layers and O layers.
