摘要
Abstract
Nineteen volcanic and magmatic rock samples were collected from the Jinding leadzinc deposit and its surrounding areas in Yunnan. The ICP and AES analyses, referred to the previous results, show that the metal minerals and altered rocks in the Jinding lead-zinc deposit display a decreasing trend of ∑ REE from the early to late stages of mineralization, and similarities in REE distribution patterns, indicating that the ore fluids are characterized by high LREE enrichment, markedly negative δCe anomaly and slight δEu anomaly. These REE distribution patterns exhibit striking similarities to those of the Pliocene trachyte in the study area, both of which are similar in ∑REE, LREE/HREE ratio, δEu and δCe. The ore fluids besides the basin fluids in the deposit are also closely related to those associated with Pliocene trachyte magmas.关键词
