The Process Of Magmatic Differentiation Explains How

Webformation of mineral deposits. In mineral deposit: Magmatic cumulates. Magmatic segregation is a general term referring to any process by which one or more minerals become locally concentrated (segregated) during the cooling and crystallization of a magma. Rocks formed as a result of magmatic segregation are called magmatic … WebDifferent magma compositions obviously result in different igneous rocks. The other factor which contributes to the differences in igneous rocks relates to the length of time it took for the magma to crystallize. In general terms, the faster the rate of cooling (common to extrusive, volcanic rocks), the smaller the resulting mineral grains. WebJun 30, 2024 · Magma differentiation is incredibly complex, and no single volcanic system is completely identical to another. The underground ‘plumbing’, the melting processes within the mantle and the type of plate boundary that forms the volcano all have complex controls on its development as well as the frequency and type of eruption. designer winter scarves women
