| 金矿床的地质找矿问题是当前广大地学工作者比较关心和注意的问题。本文为作者1987年10月在首届全国冶金地质金矿讨论会上所作的学术报告,经修改补充而成。主要从金矿床的一些地质特征,如岩石、构造、成矿时代、矿源岩和围岩蚀变等方面的特殊性,提出金矿地质找矿问题的一些设想及应该注意的问题,和大家共同讨论。 |
| 英文摘要: |
| This paper sums up the globle gold ore deposits which are different from other metal oredeposits characterized by occuring in various rocks, being controled by fractures, having a timeinterval between the age of the enclosing rock and the deposit, having source beds and specialalteration patern in the enclosing rock. Based on this the author points out the direction to searchfor gold ore deposits in China and the problems which must be taken care of. He considers that goldand copper has similar geochemical behavior therefore re-investigation and re-assessment of gold should be carried out in the cooper mining areas; that gold abundance should be surveyed in specialhigh carbon-bearing horizons and attention should be paid to mesozoic volcanic rock areas and thecontinuing oxidation zones; that in prospecting for gold the clue for PGE can not be oversighted andit must be careful to use normal Pb isotopic data in gold metallogeny research. Because gold deposittypes are not settled it is possible to find new type of gold deposit in China the Chinese geologists areencouraged to smash troditional gold metallogeny theories and make a breakthrough in gold prospecting. |
