It is the first time that the authors have p roposed that the Laozuoshan gold-polymetallic ore deposit in Heilongjiang Prov ince was formed in the calc-alkaline series environment at the margin of an act ive continent.展开更多

After ore prospecting in two years, nine new blind ore bodies were found, among which four ore bodies contain 4218. 1 kg inferred intrinsic economic re- sources （ 333 ）, and mitigate the crisis situation of mine reserves. At the same time, lots of significant geophysi- cal and geochemical anomalies were found in the peripheral, which provide a basis for further prospecting.展开更多
