使用矿物温度计和压力计时应注意的几个问题

使用矿物温度计和压力计,除搞清矿物的共生关系和精确的化学成分外,还必须搞清变质期次,矿物的世代、内部结构以及成因,有针对性地选用单矿物,才能获得预期效果。

SOME PROBLEMS MERITING ATTENTION IN USE OF THE MINERAL GEOTHERMOMETER AND GEOBAROMETER

The method of application of the distribution characteristics of isomorph- ous components of paragenic minerals in the determination of the T-P conditions of the formation of minerals and their paragenic association has been adopted by many geologists.In practice,the author has realized that in use of the above- mentioned method one should not only get a clear understanding of the para- genic relationship of minerals and the exact chemical composition but also undertake detailed field observations and in-door studies on rocks.Expected results can only be achieved by selecting specific monominerals on the premise of gaining a clear knowledge of the metamorphic stages,mineral generations. internal structures and origin of minerals.
