WebFeb 8, 2011 · In the Ni/(Cr + Mn) vs. Ti + V diagram (Fig. 5), fields for IOCG, Kiruna-type, porphyry Cu and Fe-Ti and V deposits are well defined. Fe-oxide minerals from skarns generally have low Ti + V concentrations, but display variable Ni/(Cr + Mn) ratios, preventing definition of a compositional field for skarn deposits in the Ni/(Cr + Mn) vs. Ti + V ... 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…
