Some rocks contain only one kind of mineral. Limestone (rock), for example, is often pure calcite (mineral). Anorthosite (rock) is made mostly or entirely of plagioclase (mineral). Quartzite (rock) may be made only of quartz (mineral). Dunite (Figure 1.29), an igneous rock that crystallizes from magma, is often nearly 100% olivine (mineral).A rock is an indefinite mixture of naturally occurring substances, mainly minerals. Its makeup may vary in containment of minerals and organic substances, and its composition is never exact. Rocks can be composed of tiny microscopic grains of minerals or organic substances to coarse mineal agglomerates where the individual minerals are easily ...A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure.
