WebA mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Weborganic sediments: precipitated or accumulated by biological means. Many plants and animals precipate hard parts made for example of calcite and leave organic sediments behind. Limestone is an example of an organic sediment. Burial of the sediment (or igneous rock) increases the pressure and temperature of the rock and they begin to cook.
