Peridotite is a coarse-grained, dense igneous rock composed mainly of olivine and pyroxene minerals. It is typically green in color due to the high concentration of olivine. Peridotite is commonly found in the Earth's upper mantle and is important in the formation of oceanic lithosphere.
Yes, a mineral can be composed entirely of one element. For example, native elements such as gold, silver, and copper are minerals that consist of only one type of atom.
Quartz is a common example of a monominerallic rock because it is composed almost entirely of the mineral quartz. Other monominerallic rocks include limestone (composed of calcite) and gypsum (composed of gypsum).
Alaska has the most Islands of any state in the U.S. Florida is second with about 4,500.

Granitic Composition
No, the polar caps of Mars are not believed to be composed entirely of frozen carbon dioxide. The polar caps consist of a mixture of water ice and carbon dioxide ice (dry ice). The carbon dioxide ice is most abundant during the winter.

An ionic compound.
Neutronium is theorized to be the densest form of matter. It is composed entirely of densely packed neutrons without any protons or electrons, and it is believed to exist in the cores of neutron stars.
