Contrast the difference in crystalline structure among kaolinite, smectites, fine-grained micas, vermiculites, and chlorites.

There are two basic processes by which silicate clays are formed by weathering of primary minerals. Which of these would likely be responsible for the formation of (1) fine-grained mica, and (2) kaolinite from muscovite mica? Explain.
