摘要: 从果洛龙洼地区较有利的金成矿地质环境和地球化学特征入手，阐述了该区石英脉型和构造破碎带型金的矿化特征和蚀变特征.其中，厚脉状石英脉型金矿化规模较大，由近似纯的石英构成，金最高品位35.3×10-6，预测金资源量大于5t，属可供普查的中型矿床，为本区新的成矿类型，对于今后找矿工作具有指导意义.

Abstract: Luoguolongwa Au anomaly is occurred in Dulan County,Qinghai Province,Northwest China.The anomaly is controlled strictly in Lower Carboniferous strata.The assemblage of an omalous elements is mainly Au,associated with Ag,Pb,Cu and Co.The anomaly is high in strength and large in scale,with three obvious zones and two concentrated centers.Quartz vein type of gold mineralization is dominant in the anomalous district.The lodes are composed of almost-pure puartz,with the highest gold grade up to 35.3×10^-6 and a reconnaissance resources over 5 t.The area is potential for medium sized gold deposit.The mineralization should be a new type in the area.It is an important guide for the gold prospecting there.
