Gypsum := CaSO4.2H2O
so it is Not an Oxide.
Gypsum and orthoclase feldspar are in the monoclinic crystal system.
Any metal oxide, for example magnesium oxide.

It is hardness. Calcite is harder than gypsum.
The chemical composition of cement is Calcium oxide, Silicon dioxide, Aluminum oxide, Iron oxide, water, and sulfate. They mix, crush, and blend together limestone, silica (sand and other materials), aluminum, iron, and gypsum.
Yes, gypsum can be found in deserts. A good example is White Sand National Monument in the Chihuahuan Desert in New Mexico.
Hematite
The metal itself and oxygen. For example, in ferrous oxide or ferric oxide, there is iron and oxygen.
The oxidation of a metal produces a metal oxide. For example, calcium + oxide -> calcium oxide
(the metal) oxide for example aluminum oxide
