Is sphalerite a mineral or a rock
one mineral that has sphalerite structure. 3. No foreign mineral was observed in microscope examination of slides and polished sections. 4. Microchemical tests of the coarsely crushed but not powdered sphalerite did not free any mercury but were negative, as ex pected if the mercury was a part of the lattice.According to the Lunar Reconnaissance Orbiter Camera website, the moon has a crust that is composed of rocks such as anorthosite and basalt. Anorthosite contains the mineral plagioclase feldspar which gives the rock its light color.
