Characteristics Of Quartz REE Geochemistry And Its Application To Mineralize Period Partition Of No.53 Ore Vein In Linglong Gold Deposit

Jiaodong is the most important gold producting area in China,Linglong Gold Deposit is noted in Jiaodong area.Characteristics of quartz REE geochemistry and multi-mineralize period of No.53 ore vein in Linglong Gold Deposit is the research object.Plenty of quartz samples,rock samples and multistage hydrothermal evidences in Linglong Gold Deposit had been collected.Bass on the research,the REE pattern of quartz veins in No.53 ore vein can be divided into two models.Positive Eu anomaly,flat LREE and left inclined HREE model and flat model.The former occur widely and part of them traversed by lamprophyre dikes.The latter occur with,as well as part of them altered lamprophyre dikes commomly.The results combined with geological observations and quartz veins REE patterns is that No.53 ore vein in Linglong Gold Deposit is a product of multistage hydrothermal.The positive Eu anomaly,flat LREE and left inclined HREE model quartz veins form early,then lamprophyre dikes occur,and flat model quartz veins form last.What causes two different quartz veins REE patterns may be two different quartz veins diagenetic(mine)substances.Thus,the quartz veins REE can be classified as supporting evidence of mineralization periods.
