Geochemical characteristics of primary halos and ore-search prospecting in the depth of the Zijinshan copper-gold deposit, Fujian province
摘要
Abstract
Based on systematic collection of rock and ore samples from 41 drill holes along No. 4 and No.11 exploration lines in the Zi-jinshan copper-gold deposit of Fujian Province,the authors drew a contour map of primary halos,established vertical element zoning se-quence and orebody denudation guidelines and, in combination with characteristics of the indicator elements in the depth,made a pre-diction of concealed orebodies. For gold orebody, the near-halo is Au-Ag-Zn1 , and the rear halo is Bi-Ga-Mo-Sn-Ti-Co-Ni-W1-V, whereas for copper orebody, the front halo is Hg-Sb-As, the near halo is Cu-Pb1-Zn2 , and the rear halo is Be-W2. The evaluation of the denudation of the orebody shows that the high-sulfur copper orebody pinches out to the depth. The abnormal morphology and ele-mental composition of F-Mn-Pb2-Zn3 in the depth is consistent with the characteristics of a typical porphyry deposit, the porphyry body extends to the periphery of the deposit, and the deep alteration mineral assemblages, metal mineral assemblages, fluid inclusion char-acteristics show that there may exist a porphyry Cu ( Mo) deposit in the depth of the southwest part.关键词
