Question

The weathering of the primary phyllosilicate minerals (chlorites and micas) is a relative com­plex process. Describe how the process occurs, as well as the crystal–chemical alterations in the minerals’ structure that lead to a relatively more stable weathering product for each of the following transitions: a. Trioctahedral chlorite to vermiculite b. Biotite to vermiculite c. Muscovite to vermiculite

Preeti · Accepted Answer

Phyllosilicates, formerly known as disilicates, includes serpentine, talc, chlorite, micas etc. They form an important group of minerals. Phyllosilicates are also known as sheet silicates. 
The six-membered rings of interconnected SiO44- tetrahedra, extending outward in infinite layers forms the basic structure of sheet silicates. 
Vermiculite is either trioctahedral or dioctahedral. The octahedral sheets are held together by vender wall forces. Vermiculite is a mica that is a trioctahedral hydrated magnesium-iron-aluminium layered silicate of varying composition.
