摘要
温泉钼矿是2000年在西秦岭发现的一个大型钼矿床,该钼矿床的发现结束了西秦岭成矿带无大型钼矿的观点,钼矿床产于温泉复式岩体二长花岗斑岩内外接触带及其裂隙系统中。通过对该区1:20万区域化探异常的研究,Mo、W、Cd、Bi、Ag与成矿有关的异常及亲酸性元素Be、Li、Sn、Th等元素的异常在复式岩体的晚期小岩体中发育,其异常的内带基本与晚期小岩体的范围一致,这些元素的异常是寻找该区斑岩型钼矿的直接指示元素。
WenQuan molybdenum deposit was found in 2000 in the west QinLing as a large molybdenum deposit , which end the view that no large scale molybdenum deposit exist in the west QinLing mountain metallogenic belt. The molybdenum deposit is situated in internal and external contact zone and its fissure system of monzonitic granite porphyry in Wenquan complex massif. Based on research of the 1：200000 regional geochemical anomalies, anomalies of Mo, W, Cd, Bi, Ag re- lational to mineralization, and the anomalies of close acid element Be, and Li, Sn, Th elements in the late develop of small rock mass in the complex massif. The abnormal inside take is basically consistent with the scope of the late small rock mass, these anomalies of elements are the guidance to prospecting the porphyry molybdenum deposit.
