柿竹园超大型钨多金属矿床,是幔拗区地壳加厚深熔和元古宇基底剪切熔融产生的岩浆,在燕山早期侵入活动中形成的。其成矿作用,包括:地壳熔融岩浆分异、熔—流体不混熔相分离成矿和地层物质淋滤—蒸馏—对流等联合成矿作用。成矿条件,具有:①特富的F、Cl、B元素组合和成矿元素的岩浆—热液熔—流系统;②充足的矿源及挥发份源的多源补给;③侏罗纪蓄水盆地提供渗滤、对流的水源和部分动力;④位于构造有利的地块边绿,多组断裂岩浆成矿带的交切热柱体上;⑤在极富的F、W、Sn、Mo、Bi、Pb、Zn地球化学区中;⑥以及高挥发组分在极优的Al、Si介质中对成矿物质的搬运;⑦在上部碳酸盐介质中交代、充填定位等优越的成矿条件。
The Shizuyuan super-large tungsten-polymetallic deposit is formed by thickening and deep melting of mantle-braided area crust and magmatic basement shear melt, which formed during the early intrusion of Yanshan. The mineralization includes the crustal melting magmatic differentiation, the melt-fluid immiscible phase separation and mineralization, and the stratigraphic leaching-distillation-convection combined mineralization. The ore-forming conditions include: (1) magmatic-hydrothermal melt-flow system of F, Cl, B elemental assemblages and ore-forming elements in Tefi; (2) sufficient sources of minerals and multiple sources of volatile sources; (3) Jurassic impoundment The basin provides the infiltration and convection water source and part of the motive force; ④ It is located on the intersecting hot cylinder of the margin green and multi-group fracture magmatic metallogenic belt with favorable structure; ⑤ In the extremely rich F, W, Sn, Mo, Bi, Pb, Zn geochemistry area; ⑥ as well as high volatile components in the excellent Al, Si medium on the ore-bearing material handling; ⑦ in the upper carbonate medium replacement, filling and positioning of superior metallogenic conditions .
