| 摘 要： | 通过锑元素的地层地化、区域地化场及稀土元素、硫、硅、钐－ 钕、氢氧同位素研究，对锡矿山超大型锑矿床的成矿物质来源作了详细探讨，并分析了其形成机理，认为赋矿层泥盆系不是矿源层，前泥盆系老地层才是主要的矿源层，成矿流体中的水是以大气降水为主、有岩浆水和变质水加入的混合水，本矿床属中低温异地沉积－ 改造型矿床。该区的下步找矿方向应主要是西部和西南部及深部的棋梓桥组灰岩层

| Abstract: | Based on the regional geochemical field, REE and isotopic geochemistry, source of ore-forming materials, metallogenic mechanism are inquired into. It is suggested that not the ore-hosting Devonian but pre-Devonian is the source beds, and the metallogenic fluid is the mixing of magmatic water, metamorphic water and meteoric water. It is genetically a sedimentary--reformation ore deposit. The west, southwest and deep Qiziqiao Formation limestone are the prospects for current and next prospecting. |
