| 摘 要： | 镇（安）旬（阳）地区锑金矿化分布，与其区域地质地球化学因素，陆源断陷盆地沉积岩相变化，后期构造作用密切相关，认为镇旬地区为扬子与华北板块边缘对接过渡活动带，形成局部扩张断陷沉积盆地环境。海底同生断裂的发育，使盆地中心局限台盆环境造成陆源物质、内源组份和深部物质的混生，以及为深部含矿热液上升提供通道；在后期脆－韧性剪切变形构造叠加，地下热卤水循环改造作用，形成层控式细脉浸染型锑金矿床。该地区锑金成矿物质来源丰富，沉积构造环境优越，后期控矿构造发育，显示了潜在的细脉浸染型锑金矿床的找矿前景。

| Abstract: | The Zhen(an)-Xun(yang) area is a transitional mobile belt between Yangtze Platform and Northern China Platform, and an environment where formed local sedimentary basin in extension graben, where the Sb Au distribution is closely related to the regional geology and geochemistry, facies change of the sedimentary rocks in the graben basin from continental sources, and the later tectonism. Development of the contemporaneous fault at the sea floor made the continental source materials, internal source composition and the deep materials to be mixed in the local platform basin inside the basin center, that had provided ascending pathway for the deep mineral bearing hydrothermal solution. And strata bound Sb Au deposit of fine vein dissemination type had been formed by the later superimposition of brittle ductile shear fault and by the circulation and deformation of the hot brine underground. The area was aboundent in Sb Au mineralization Sources, favourable in sedimentary and tectonic setting and developed in later ore controlling structure, which show a potential ore prospecting perspective for fine vein disseminated type Sb Au deposit. |
