在都龙超大型锡多金属矿床外围西部的金石坡矿段勘查发现,该矿段深部距离燕山期隐伏花岗斑岩体100m附近或花岗斑岩脉体周边存在较好W-Cu-Mo矿化,其赋矿围岩是中寒武统田蓬组底部碳酸岩夹石英云母片岩。新发现W-Cu-Mo矿化的围岩蚀变较强,但与都龙矽卡岩Sn-Zn主矿体的蚀变类型不同,其矽卡岩化以石榴石、透辉石等干矽卡岩为主。W-Cu-Mo等成矿元素以白钨矿、辉钼矿和黄铜矿等矿物相形式存在,呈细脉状、星点状和团斑状产于花岗斑岩硅化接触带及节理裂隙发育的矽卡岩化大理岩、碎裂状石榴石透辉石矽卡岩中。W-Cu-Mo矿化在整个都龙矿田深部都较普遍,是今后勘探和开采中值得重视的新矿化类型。都龙超大型锡多金属矿床深部W-Cu-Mo矿化的揭露,表明该矿床成因类型属于与燕山晚期花岗斑岩有关的矽卡岩型多金属矿床。
The exploration of the Jinshippo deposit in western part of the periphery of the Dulong super-tin-polymetallic deposit shows that there is a good W-Cu-Mo in the deep part of the ore body near the 100m Yanshanian concealed granite porphyry or in the periphery of the granite porphyry. Mineralization, the ore-hosting rock is Carbonate rock folder quartz mica schist at the bottom of mid-Cambrian Tiantong Formation. The newly discovered W-Cu-Mo mineralized wall rock has a strong alteration but differs from the alteration type of the main Sn-Zn ore body in the Du Long skarn. The skarnization of the W-Cu-Mo mineralized garnet is garnet, diopside, etc. Skarn based. W-Cu-Mo and other metallogenic elements are present in the form of scheelite, molybdenite and chalcopyrite and other mineral phases, showing fine veins, star-like and group-like formation in the contact zone and the fissure of granite porphyry Developed skarn marble, fragmented garnet diopside skarn. The W-Cu-Mo mineralization is common in deep Dullong orefields and is a new type of mineralization worth paying attention to in exploration and exploitation in the future. The revelation of the deep W-Cu-Mo mineralization in the Du Long super-tin-polymetallic deposit shows that the genetic type of this deposit belongs to the skarn-type polymetallic deposits related to late Yanshan granite porphyry.
