WebApr 15, 2024 · The magmatic process within upper crust encompasses various contents such as the transition between magmatic and hydrothermal systems and changes in oxygen fugacity (ƒO2), which ultimately play key roles in the formation of porphyry Cu deposits (PCDs). However, tracing these magmatic processes, especially in porphyry systems, is … Most igneous rocks have some degree of porphyritic texture. This is because most magma from which igneous rock solidifies is produced by partial melting of a mixture of different minerals. At first the mixed melt slowly cools deep in the crust. The magma begins crystallizing the highest melting point minerals closest to the overall composition first, in a process called fractional crystallization. This forms phenocrysts, which usually have plenty of room for growth, and form l… desk chair for school
