Rare Earth Element and Trace Element Geochemistry of Wolonggang Antimony Enrichment Area Deposit and Its Tracing Significance for the Origin of Metallogenic Elements in Dongkunlun
摘要
Abstract
Combined with system field investigation and ore-forming geological conditions of the Huangyangling antimony deposit, the geochemical characteristics of the deposit are summarized, the origin of the ore-forming materials is ascertained, and ore-forming mechanisms is discussed according to the major element analysis and trace element analysis.The results show that the Eu has no Eu anomalies and performing Eu flat-type, moderate depletion of Ce.This reflects that ore-forming fluid basically belongs to neutral environment and original hydrothermal depletes Ce in the ore-forming fluid.There are characteristics of enrichment of LREE, depletion of HREE and nega-tive anomaly of Ce, which shows that the orebody and the surrounding rock are homologous.REE distribution patterns performed by the surrounding rock and quartz are very similar to the upper crust, which reflects that the REE moves little in surrounding rock and the effect of the ore-form-ing fluid to surrounding rock is very small.That explants that REE of the ore vein mainly comes from deep crust and the contribution ofhost rock is small.Compared with the REE distribution pat-tern of hydrothermal fluid of the submarine and spout-sediment deposit, Huangyangling antimony deposit is obviously different, which the metallogenic material mainly comes from the deep crust and the ore genesis of it belongs to post magmatic hydrothermal typeof antimony deposit.关键词
