Genesis of Fluorite Deposits and Prospecting Direction in Northwestern Zhejiang Province
摘要
Abstract
In recent years, a great breakthrough has been made in the exploration of hydrothermal fluorite deposits in northwestern Zhejiang Province, with large- and middle-scale fluorite deposits found in Changshan, Chun' an, Kaihua, and Anji counties. These deposits are mainly distributed in the inner and outer contact zones of Yanshanian( Early Cretaceous) granite, and their mineralization is closely related to magmatic intrusion. Based on the study of the metallogenic geological background and geochemical characteristics and ore-control structures of seven typical fluorite deposits in northwest Zhejiang province, this work discussed the relationship between the rock mass and fluorite mineralization. The genesis of the fluorite deposits can be divid-ed into two categories:the late magmatic hydrothermal fluorite deposits related to A-type granites and those related with I-type granites. This work made an analysis of metallogenic sources, metallogenic temperature, REE geochemical characteristics of fluorite, metallogenic epochs and metallogenic en-vironments of the deposits, and discussed the genesis of the major fluorite deposits. Furthermore, combined with the geochemical characteristics of the F-element and the features of the residual gravity anomalies, it is suggested that the future prospecting of the fluorite deposits should be conducted in the following places:the distribution area with high-Fgranites, the F-element anomaly area and the area with negative residual gravity anomalies.关键词
