矿物中的气液包裹体(以下简称包裹体)是保存至今的成矿流体的样品.对于它的研究可以获得成矿流体的各种物理化学参数(温度、压力及成分),从而解决其来源及演化、矿床成因、成矿过程等重要课题.包裹体的研究结果还有助于地球化学找矿及某些机理问题的解决.研究包裹体的方法有多种,但所得到的数据可归为两类:一是温度和压力,二是成分.前者在国内已普遍开展,无论在方法原理、仪器装置、数据的解释与应用等各方面都已取得一定成绩;但是在包裹体成分研究方面与国外相比差距较大.本文着重介绍我们近两年开展这项工作的初浅认识和体会.
The gas-liquid inclusions in minerals (hereinafter referred to as inclusions) are the samples of ore-forming fluid preserved so far, and its research can obtain various physicochemical parameters (temperature, pressure and composition) of ore-forming fluids to solve their sources And the evolution, the genesis of the deposit, the process of metallogenesis, etc. The results of the inclusion study also contribute to the geochemical prospecting and the solution of some mechanistic problems. There are many ways to study the inclusion, but the data obtained Are two types: one is temperature and pressure, and the other is composition. The former has been widely developed in China and has achieved some success in terms of methodology, instrumentation, data interpretation and application, etc. However, Compared with foreign countries, the gap is large.This article focuses on the initial understanding and experience of carrying out this work in the past two years.
