引言大约在一个世纪以前人们就在世界范围内发现了金矿床和铁建造具有共同伴生组合关系。金矿床中金的来源有同生的,也有后生的。在加拿大除了由砂矿床转变而来的金矿外,大多数金矿产在岩脉、剪切带和破碎带里。可见在金矿的沉淀过程中构造因素是十分重要的。铁建造是原来的化学沉积物,它一方面作为同生金的来源,另一方面,这些硬而脆的燧石质岩石又为矿脉的形成提供了一个有利的环境。岩石的构造控制了金的
INTRODUCTION About a century ago people around the world discovered that gold deposits and iron construction have a common associated relationship. The origin of gold in the gold deposits is homologous, but also epigenetic. In addition to the gold deposits that have been converted from the sand deposits in Canada, most gold deposits are found in dikes, shear zones and crushed zones. It can be seen that the structural factors in the precipitation of gold deposits are very important. Iron build-up is the original chemical deposit that, on the one hand, serves as a source of allogenic gold. On the other hand, these hard and brittle chert rocks provide an advantageous environment for the formation of veins. The structure of the rock controlled the gold
