Answer to Question 1

Olivine, pyroxene, amphibole, biotite/muscovite/mica/clay, quartz/feldspar.

Answer to Question 2

In many minerals, the chemical composition does not vary. In some minerals, one element can
substitute for another if the atoms of the two elements are nearly the same size and the same charge. In
olivine, magnesium and iron can both fill the cation position, so the chemical composition for the
mineral is (Mg, Fe) 2SiO4.
