四川省红原县新康猫金矿床构造控矿规律
|
摘要
新康猫金矿床是2001年以来在阿坝地块南缘发现的迄今为止属四川省最大规模的金矿床,矿体既受一定的层位和岩性组合控制,又受构造控制。矿体总体呈北西向展布,北北东向构造与北西向构造复合部位是最重要的赋矿部位。垂向上,构造对成矿的控制作用具有明显的分带性,浅部控矿构造为张裂脆性构造,向下控矿构造变为韧性构造。深部较大规模的断裂多为地表多条较小规模的容矿断裂逐渐汇聚而成,矿体品位明显变富,厚度明显增大。新康猫金矿床及其外围,成矿地质条件良好,矿化信息显著,找矿前景巨大。
So far, Xinkangmao gold deposit is the largest one in Sichuan province. It has the general characteristics of finely disseminated gold deposit in northwest of Sichuan. Ore body occurrence in the Upper Triassic turbidite deposition of sedimentary sand slate construction, controlled by the North West to layer ductile-brittle shear zone. this orebody have composites Ore-controlling regularity. It must be the combination of lithology and layer control, and controlled by structure. Specially, the construction of multi-site group is an important metallogenic site. Although mine(mineralization) was in the North West to the overall distribution, but to the North-North East and North West tectonic structure of the site is to find rich direction of the main ore body.The deposit with Zoning control in the vertical structure of the mineralization, its superficial is rifted brittleness tectonic Ore-controlling, but its below become Orecontrolling of the toughness.On the surface, several host fracture of small scale may accumulate a big scale fracture along the deep, the thickness of mineralization is increasing notable, and the grade have trend with becoming rich obviously.
