柿竹园矿床形成于极为有利的地质 地球化学条件 ,主要是 :( 1 )特别富集挥发分与钨锡成矿元素的地球化学背景 ;( 2 )有特富挥发分和成矿元素的岩浆热液 ,即熔 -流体系统 ;( 3)充足的矿源及挥发分源的多源补给 ;( 4)侏罗纪蓄水盆地提供渗滤、对流的水源与部分动力 ;( 5 )极有利的构造部位 ,包括 :地块边缘环境、多组断裂面交叉部位、表层缓倾剪切面与复向斜轴部复合部位 ;( 6 )多期次岩浆热液活动和矽卡岩、云英岩及脉体的叠加 ;( 7)极优的运矿与聚矿的地层介质环境 ,即在下古生界及震旦系硅铝质细碎屑岩中运矿 ,在泥盆系碳酸盐及蚀变的矽卡岩中定位 ;( 8)极佳成矿机构的匹配 ;( 9)良好的保存和产状条件 .最后提出了两个成矿模式图
The Shizuyuan deposit is formed in extremely favorable geo-geochemical conditions, mainly including: (1) the geochemical background of the special enrichment of volatile components and tungsten-tin mineralization elements; (2) the magmas of Teflon-rich volatiles and metallogenic elements (3) Adequate multi-source replenishment of ore sources and volatile sources; (4) Jurassic water basins provide sources and partial motive of percolation and convection; (5) Extremely favorable The tectonic positions include the marginal environment of the block, the intersections of multiple sets of fault planes, the complex geostrophic shearing planes and the synclinal syncline complex; (6) multi-stage magmatic hydrothermal activities and skarn, And veins superposition; (7) excellent ore and ore accumulation in the stratigraphic media environment, that is, in the Lower Paleozoic and Sinian Si-Al-rich fine rocks transported in the Devonian carbonate and Alteration of skarn orientation; (8) excellent ore-forming mechanism matching; (9) good preservation and production conditions.Finally, two metallogenic patterns
