A. Muscovite mica [KAl2AlSi3O10(OH)2 ]has nearly the same chemical formula as biotite mica [K(Mg, Fe)3AlSi3O10(OH)2]. They both form crystals that are platy sheets. Based on their chemical formula, predict how they are different in appearance B. The igneous rock gabbro is made up primarily of ferromagnesian silicate minerals. Predict what gabbro looks like. Explain your answer.
