REE Geochemical Characteristics of Green Rock in Fozichong Lead- Zinc Deposit and Genesis Implications
摘要
Abstract
The widely distributed green rock in Fozichong orefield is closely related to mineralization, but extremely controversial on the genesis. Based on the field work, the green rock can be classified into four types: the beded type, the massive type, the veinlike type and the breccia type. The REE geocheraisty reveals that it is characteristic of high XREE, LREE/HREE and LaN/YbN, negative Eu anamoly, and no Ce anamoly, similar to granite porphyry. The REE content of green rock is progressively reduced with the intensive mineralization. Comparative study on the geological and geochemical characteristics of the typical skarn rock and exhala-tive rock, it is suggested that the green rock of the Fozichong lead-zinc deposit should be the post-magmatic hy-drothermal metasotnatic product and closely related to mineralization. It has important significance on the genesis of the deposite and the research of metalloge nesis of the Fozichong ore deposit.关键词
