in fact even though biological races do not exist the concept of race obviously is still a reality as is racism these are prevalent and persistent elements of our everyday lives and generally accepted aspects of our culture thus the concept of human races is real
Common Metamorphic Minerals Metamorphic rocks form when pre-existing rocks (igneous, sedimentary, or metamorphic) are exposed to high temperatures and pressures under the Earth's surface. Some pre-existing minerals, unstable at the higher temperature and pressure conditions, transform into new minerals.Others recrystallize and grow larger.etamorphic rocks tend to be dominated by minerals you already know: feldspar, quartz, muscovite, biotite, amphibole, and calcite/dolomite. However, a few minerals are found exclusively or mainly in metamorphic rocks:
Due to the environment and chemical elements in the parent rock, specific minerals are formed. Metamorphism is between a total melt of solution that form igneous rocks and the deposition of sediment under a normal environment that forms sedimentary rocks.ome of the minerals that make up those rocks also change properties as heat and pressure is applied. Polymorphs of minerals at different phases result and thus some minerals are only found in metamorphic rocks.
