现在岩石学、矿床学的实验一般用样品是几十毫克、甚至十几毫克,其目的是要精确化。但是许多事实说明,这种精密的实验工作并不能完全解决矿床的成因。要解决矿床成因的问题,至少必须回答下面三个问题:(1)有用金属矿物是在什么条件下形成的;(2)有用金属矿物是如何富集为矿石的;(3)矿石如何具有一定的量,并达到经济上可开采的要求。实验岩石学和实验矿床学的资料一般只说明了第一个问题,对后两个问题是无法
Now petrology, ore bed experiment with the general sample is dozens of milligrams, or even a dozen milligrams, the purpose is to be accurate. However, many facts show that this sophisticated experimental work can not completely solve the cause of the deposit. To solve the genesis of the deposit, we must at least answer the following three questions: (1) under what conditions are the useful metal minerals; (2) how the useful metal minerals are enriched as ore; (3) how the ore has a certain And meet the economically exploitable requirements. The data of experimental petrology and experimental mineralogy generally only show the first problem, but not the last two problems
