Igneous Rocks Andesite 017 Basalt 018 Dolerite 0062 Diabase 016 Diorite 013 Norite 009 Dacite 005 Granite 005 GranodioriteTona. A homogenous, naturally occurring substance with definable internal structure is called mineral. .. Mode of occurrence of minerals:. (1) In igneous and metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc.. Metamorphic Rocks . Are Composed of Sedimentary, Igneous, or Metamorphic Minerals that Have Recrystallized.. Marble from Carrara, Italy. Pre-existing sedimentary, igneous, or metamorphic rock changed to a new assemblage of minerals. . Contact Lens Associated . Microbial . Keratitis. Jimmy Lim. 1 . , Muhammad A. Ismail. 2. .
