Geological and Geochemical Characteristics of Orebody 13 of Hadamengou Gold Deposit, Inner Mongolia
摘要
Abstract
The No. 13 ore-vein of Hadamengou gold deposit in Inner Mongolia occurs mainly in the auriferous quartz K-feldspar veins. Most of the gold occur in inclusion, and a few exist in the gap of pyrite. Gold particle size is approximately 0. 05 - 0. 25 mm. Based on characteristics of ore-forming elements combination, Au and chalcophile elements such as Ag, Bi, Pb are highly correlated, which shows the gold mineralization is closely related with polymetallic sulphides. According to the data analysis, space maps are drawn and the establishment of the primary halo axial vertical zoning sequence; Au-Pb-( Ni-Co-Ag-Zn-As-Hg)-Cu-W-Bi-Sb-Mo is done as well. Multistage superposition of mineralization lead to that Ag, Sb, As and other elements anomalies coexist and zoning characteristics of part axial vertical zoning sequence is not obvious. Compared with the typical gold banding sequence, the front halo element Sb appears in the lower part of the zone sequence and the geochemical parameters take a new turn at the bottom of known bodies ( near the elevation 658 m) , which imply the existence of concealed orebody in the deep. The subsequent production practices also verified this speculation.关键词
