本文目的在于讨论一些与热液矿床成因有直接关系的流体动力学方面的问题,这些矿床是在漫长的时间中(大约为10~4—10~5年)由热水溶液通过地壳局部部位进行富集形成的。热液矿床便成为液体流——Q体系的遗留痕迹。 这里我们着重介绍二种热液成矿方式和一个实例: 一、热流体注入到干的透渗环境中 这种成矿方式是与火成——热液说的矿石成因概念是一致的。在花岗岩浆结晶的过程中释放出的金属卤水溶液是成周期性地沿可渗透带注入到围岩中,并
The purpose of this paper is to discuss some of the fluid dynamics problems that are directly related to the genesis of hydrothermal deposits that were enriched by hot aqueous solution over localized parts of the earth’s crust over an extended period of time (approximately 10 to 4 to 10 to 5 years) Set formed. The hydrothermal deposit becomes the remaining trace of the liquid stream-Q system. Here we highlight two kinds of hydrothermal mineralization methods and an example: First, the hot fluid injection into the dry seepage environment This metallogenic method is consistent with the concept of ores - hydrothermal ore origin. The metal brine solution released during the crystallization of the granite slurry is periodically infiltrated into the surrounding rock along the permeable zone and
