2 Soil 3 Landscape Lithosphere Lithosphere The lithosphere is a rigid part of the earth that includes the earths crust and part of the upper mantle Ex Mountains plains volcanoes etc. 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. . Granite, Alkali Feldspar Granite, Granodiorite, Quartz Monzonite, and Monzonite. 2. IUGS Intrusive Igneous Rock Chart . 3. “Granite”. Rocks in this lab are plutonic. They formed by very slow cooling and show corresponding large crystals. Mineral Characteristics. What is a mineral?.
