Gold ore provinces and formations

Granitic magmas result from refusion of sedimentary rocks. Metals associated in gold ore formations are mobilized by magmatic and etamorphic activity from volcanic and sedimentary rocks of a geosynclinal series. The comportment of metals during the processes of mobilization, transfer, and deposition is ruled by their atomic structure and electromagnetic properties. Ionic density (d_i) and concentration coefficient (C_s/Cv) of the metals are chosen as coordinates for plotting the associations of metals of different gold ore formations. The degree of complexity of the associations is a consequence of the degree of heterogeneity of the geosynclinal rock series and of the intermittence or telescoping of the ore deposition process. — B.V.
