These rocks include andesite, basalt, obsidian, pumice, rhyolite, scoria, and tuff. Pictures and brief descriptions of some common igneous rock types are shown on this page. Diorite is a coarse-grained, intrusive igneous rock that contains a mixture of feldspar, pyroxene, hornblende and sometimes quartz.
For example, a sedimentary rock form is limestone that is composed only of the mineral calcite. Main rocks on earth contain minerals like magnetite, quartz, feldspar, mica, epidote etc. But more than half of the mineral types classified in geological studies are considered rare.
