“These include clay minerals such as kaolinite and talc, micas, montmorillonites, and the remainder of the asbestos minerals including chrysotile.”

“Crystals sometimes exhibit visible inclusions of micas and tourmaline as well as rarer minerals, such as cassiterite.”

“Parallel with the micas that cause the schistosity, the growth of the quartz and epidote lenses took place.”
