| 摘 要： | 根据老厂环形影象特征、地质构造环境、断裂分布、矿床地质与地球化学特征、围岩蚀变及岩浆岩脉特征,推测环形影象为隐伏花岗岩体上侵、成矿热液上涌之产物。内环为隐伏岩体突起部位,也是已知矿体的赋存空间。老厂银铅矿床成因类型不是火山岩矿床,而是与隐伏花岗岩体有关的中温热浪矿床。

| Abstract: | Based on the features of ring images, tectonic surroundings, features of cracks, geochemistry, ore deposit geology, wall-tock alteration andfeatures of veins, it has been inferred that the ring images of the Laochangarea resulted from both hidden granites intrusing and hydrothermalsolutions uprising. The inner ring is considered both as a projectingpart of the hidden granite, and as a known ore-body space-formation. Inauthor's opinion, the silver-lead ore deposit is not a volcanic deposit, buta mid-hydrothermal one which is associated with the hidden granite body. |
