Aiming to the geological characters of fluorite deposits in Shuangjiangkou of Hunan,integrating the geological backgrounds,the geological conditions,the cause of formation of deposits and the factors of controlling ores in this district,the prospecting marks offluorite deposits have been suggested and the prospecting foreground is good.

REE geochemistry of fluorite from Yixian fluorite deposit and its geological implications;

This paper has applied the cell- recurrence method and fractal box- counting method to the statistical analysis of 6 2 9fluorite deposits or ore spots in three different areas of Zhejiang Province.

Most fluorite deposits from Guangdong, Fujian and Jiangxi Provinces of South China occur in the endo-or exdo-contact zone of granite intrusions.

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.
