摘要
Based on the field work, the green rock can be classified into four types： the bedded type, the massive type, the vein-like type and the breccia type. The REE geochemistry reveals that it is characteristic of high ∑REE, LREE/HREE and LaN/YbN, negative Eu anomaly, and no Ce anomaly, 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 exhalative rock, it is suggested that the green rock of the Fozichong lead-zinc deposit should be the post-magmatic hydrothermal metasomatic product and closely related to mineralization.
