摘要
本文对我国主要蛭石矿床的地质特征进行了论述,并在此基础上探讨了其成矿规律及金(黑)云母蚀变成蛭石的地质作用,并以此为根据提出了蛭石矿床的较为合理的成因分类。
The paper detailedly account and discussed the geologic feature of vermiculite ore deposits inChina, and then discussed their mineralizing rules and the geologic process of phlogopite (biotite) changinginto vermiculite. The two process are low temperature (<200℃) hydrothermal fluid process and weatheringprocess. In this basis we present a new reasonable and systematic genetic type classification of vermiculiteore deposits.
