Exploration of the Mineralization Material Sources and Genesis of Fluorite Deposits in Silidian-Dushu Area,Henan Province
摘要
Abstract
To study the genesis of fluorite deposits in the Silidian Dushu area,establish a fluorite genesis model within the study area.Inductively coupled plasma mass spectrometry(ICP-MS)was used for rare earth element analysis to analyze the mineral sources and genesis of fluorite deposits in the study area.The analysis results of rare earth elements indicate that the rare earth distribution pattern of fluorite belongs to the light rare earth enrichment type.The Eu negative anomaly and weak Ce positive anomaly displayed in the Huangtu Gang fluorite deposit indicate a lower ore-forming temperature and a reducing environment.The Eu in the Zhoumiao fluorite deposit exhibits both positive and negative anomalies,indicating a transition from high temperature to low temperature before and after mineralization.The Y/Ho La/Ho relationship diagram indicates that the ore-forming fluid sources of the fluorite deposit in the study area may be consistent.The relationship diagram between Tb/Ca Tb/La and La+Y-Y/La indicates that the fluorite deposit in the study area is a product of magmatic hydrothermal activity,and there is a significant water rock reaction between the ore-forming hydrothermal solution of the Huanghuagang fluorite deposit and the carbonate surrounding rock.Based on the analysis of rare earth elements and the geological characteristics of the ore body,it is speculated that F in the fluorite ore comes from magmatic rocks and Ca comes from carbonate surrounding rocks;the genesis type of the fluorite deposit in the study area is a medium low temperature hydrothermal filled fluorite deposit.关键词
