众所周知,由于超基性岩浆岩中常含有铬、镍、钴、铜、铁、金刚石、石棉和铂族元素等重要矿产,以及它们与地幔岩相似,所以近年来受到人们的重视。弄清这类岩石的生成条件不仅为研究其中所含矿产的成矿作用和分布规律所必须,而且也是解决地球演化问题的一项重要基础工作。温度和压力是研究这类岩石生成条件的两项重要的基本参数,鉴于目前很 It is well-known that in recent years, ultramafic magmatic rocks have received much attention in recent years due to their close association with mantle rocks, due to the presence of important minerals such as chromium, nickel, cobalt, copper, iron, diamond, asbestos and platinum group elements. It is necessary to understand the formation conditions of these rocks not only to study the mineralization and distribution of the minerals they contain, but also to solve the problem of the evolution of the earth. Temperature and pressure are two important basic parameters for studying the conditions for the formation of such rocks. In view of the fact that
