预测在拜城某地产特大型红柱石矿的区域内,可能有较大规模原生金矿床的产出,其依据是:1.特大型红柱石矿杂岩的存在,反映出该杂岩原始有大量玄武岩浆加入;并经彻底分解分异。这种杂岩是产原生金矿床的最佳杂岩。拜城黑英山地区有金云母矿产出,金云母岩是原始有蛇纹岩浆加入转生成的标型岩石之一。因此产红柱石矿的变质杂岩,可能属碱碳-超基性-基性成因的火成杂岩,这是产金矿的重要杂岩类型。国内外产原生金矿床的杂岩中,绝大多数都有富铝的矿物岩石产出。例如兰德型金矿田中的德兰士瓦系比勒陀利亚群杂岩中,产世界上最大的红柱石矿床。从兰德系至德兰士瓦系总厚约13000米的火山沉积杂岩中,有6100米厚的熔岩、安山岩、辉绿岩等产
It is predicted that within the area of Baicheng a real large-area andalusite, the output of larger-scale native gold deposits may be based on the following: 1. The existence of the extra-large andalusite complex reflects the original A lot of basalt magma to join; and after thorough decomposition of differentiation. This type of complex is the best complex of primary gold deposits. Phyllite mica is produced in Baishan Heiyingshan area, and phlogopite is one of the type rocks with the original serpentine magma added and converted. Therefore metamorphic complex of andalusite may belong to alkali carbon - ultrabasic - basic genesis of igneous complex, which is an important complex type of gold-bearing ore. In the domestic and foreign gold deposits of primary gold, the vast majority of aluminum-rich mineral rock output. For example, the Grandeur-type Pretoria Group complex in the Rand type gold field produces the largest Andalusite deposit in the world. In the volcanic-sedimentary complex with a total thickness of about 13,000 meters from the Landes to the Transvaal, there are 6,100 meters of lava, andesite and diabase
