粤西北福田地区岩浆岩时空分布与成矿的响应

Spatial and Temporal Distribution of Magmatic Rock in Futian Area in Northwest Guangdong and Metallogenic Response

粤西北福田地区已知内生金属矿(点)床90余个,其矿化均位于花岗岩内、外接触带。分析了该区岩浆岩分布特征,阐述了岩浆岩时空分布与成矿的响应,可见矿化与花岗岩在时间上、空间上和岩性特征上密切相关。

The number of the known endogenous metal ore deposits in Futian area in northwest Guangdong is more than90. Their mineralization is all located in granite and outer contact zone. The paper analyzes the distribution characteristics ofmagmatic rock in this zone, and describes the spatial and temporal distribution of magmatic rock and metallogenic response. Itcan be concluded that the mineralization and granite are closely related to lithologic characters spatially and temporally.
