| 摘 要： | 在对阮家湾铜-钼-钨矿床白钨矿矿化进行野外及室内矿床地质工作的基础上,作者从古水文地质学和地球化学角度探讨了钨矿化机制。该矿床钨矿化具层控性,在沉积-成岩过程中,含矿地层中奥陶统碳酸盐岩中即有钨的初步富集,这主要和与含矿地层相邻的泥质岩所经历的水交替过程及地球化学作用有关,燕山晚期阮家湾岩体侵入后,钨得以再次富集,形成矿体。

| Abstract: | On the basis of field and laboratory works on the ore geological conditions and the
scheelite occurrence of the Ruanjiawan Cu-Mo-W polymetallic deposit, paleohydrogeologic
and geochemical constraints on the tungsten mineralizing mechanism are studied by the au-
thors. The tungsten orebodies of the deposit are stratabound, occurring only in the middle
Ordovician carbonate strata. Tungsten is primarily enriched in the ore-bearing hostrocks
during sedimentation and diagenesis stages. The primary enrichment is related to the hy-
drogeological and geochemical processes undergone by the argillaceous rocks adjacent to
the middle Ordovician strata. With the intrusion and emplacement of the Ruanjiawan mag-
matic stock in the late Yanshanian tectonic period, tungsten is enriched once more again
and form the orebodies. |
