铂、铬、钛和硫化铜—镍等岩浆矿床均与基性、超基性侵入体有关,但并不是每一个这种岩体都含有金属矿化.常见的是,岩类相似的侵入体在一种情况下是含矿的,在另一种情况下则不合矿,而以后者居多.这个原因至令尚未安全查清,问题在于产生含矿岩浆并形成岩浆矿床的主要控制因素还不清楚.本文试图阐明含矿与不含矿的基性—超基性成分岩浆形成过程的某些规律,并根据对硫化物与硫化物-硅酸盐系统所作的实验以及多年来对铜-镍矿床的研究和一些文献资料,说明上述几种矿床的形成条件.
Magma deposits such as platinum, chromium, titanium and copper sulfide-nickel are all related to basic and ultrabasic intrusions, but not every one of these types of rock mass contains metal mineralization. Commonly, rock-like intrusions In one case, ore-bearing, and in the other case, non-conforming, with the latter being the majority, for reasons that have not yet been safely identified and the problem is that the main controlling factor for the generation of ore-bearing magmas and the formation of magmatic deposits is not yet Clearly, this paper attempts to elucidate some of the laws of magma formation in both basic and ultrabasic ore-bearing and non-ore-bearing formations and on the basis of experiments with sulphide and sulphide-silicate systems, Deposits and some literature data, indicating the formation of several deposit conditions.
