Question
Surfaces of this mineral are common substrates for immobilizing biomolecules in AFM and electron microscopy. For 10 points each:
[10m] Name this class of minerals that includes phlogopite and biotite and exhibit perfect basal cleavage.
ANSWER: micas [prompt on phyllosilicates]
[10e] Micas are phyllosilicates, like this other class of minerals that includes kaolinites. These minerals form grains that are typically less than two microns in size, making them the finest sediments after sands and silts.
ANSWER: clay minerals
[10h] Micas are the final minerals to precipitate in the discontinuous branch of Bowen’s reaction series; immediately preceding them are these two classes of silicates respectively formed from single chains and double chains of silica tetrahedrons. Name either.
ANSWER: pyroxenes OR amphiboles [prompt on inosilicates]
