摘　　要：通过矿床成矿地质条件及控矿因素的研究,建立了乌拉嘎金矿床找矿标型。在张才沟矿化区通过地质、地球化学、地球物理等研究工作,确定出隐伏金矿体赋存的最佳部位,并实施了工程查证,钻孔70m深处见厚3m、平均品位20.4×10-6的矿体。进一步证实了预测方法的有效性,取得了满意的成果。By the research of mineralization geological conditions and mineralization controlling factors, the exploration signs of old Wulaga deposit were set up. By means of geology, geochemistry and geophysics, optimum targeting positions of the concealed orebodies were defined and verification engineering made in Zhangcaigou area, where a gold bearing ore body of 3m thick and grading at 20.4 ×10^-6 by average was discovered at the depth of 70m of the borehole, which is a further confirmation of effectiveness of the forecast with satisfactory results.
