  • Unakite is a metamorphic rock that is formed when granite or similar rock is exposed to elevated temperatures and hydrothermal fluids during the emplacement of a volcanic dike or overlying lava flow The resulting rock contains epidote, orthoclase feldspar, and quartz, and it is green and pink in colorChemical weathering can also result from exposure to water Hydrolysis occurs when silicate minerals react with water so that the mineral recombines with the water molecule to form a new mineralFor example, consider the mineral potassium feldspar Potassium feldspar is a fairly common mineral and can be found in igneous, metamorphic and sedimentary rocks.
