Rresearch Of Metallogenic Regularity And Mineralization Model Of Kalamaili Mineralization Belt In East Junggar

This paper is based on the East Junggar Kalamaili metallogenic belt of Xinjiang as the study area.It located on the combining site of Siborian plate and KazakhstanJunggar palte and it is an important part of the Central Asian Orogenic Belt.The area has experienced an important collision orogeny in the late Paleozoic,and a strong post collisional magmatic activity occurred,accompanied by mineralization.This paper mainly studies the gold is Shuangquan gold and Kubusu gold,The main object of study for the intrusion is the Huangyangshan pluton and small Hongshan rock.Based on the study of the geological characteristics,geochemical characteristics and geochronology of the typical deposits and intrusions,and then And compare each other.The main results are as follows:1?Petrology and geochemistry of gold ore samples of the Shuangquan gold deposit is rich in potassium ? magnesium and poor sodium,it blong to the peraluminous shoshonite rock series.In the process of evolution,light rare earth element enrichment and heavy rare earth deficit,Eu negative anomaly obvious.The rock has the characteristics of crust mantle mixing,and the rock is the result of rear collision;The mineralization age of Shuangquan gold deposit gold ore is303.53�0.79 Ma.2? Petrology and geochemistry of gold ore samples of the Shuangquan gold deposit is rich in Sodium,calcium and poor potassium,magnesium.it blong to the peraluminous alkalescence rock series.Eu negative anomaly obvious.Gold mineralization is similar to post collisional magmatic characteristics.Rock samples have the characteristics of crust mantle mixing.3?Petrology and geochemistry of huang yang shan and xiao hong shan is rich in Sodium,and poor in potassium,it blong to the peraluminous alkali granite rock series.The rocks are rich in high field strength elements and large ion-parent elements,which are A-type granite.Magma is crust mantle magma,and has the characteristics of post collisional granite magma.4?The contrast discovery that the content of rare earth elements and the distribution curves are very similar through comparison rare earth element of typical deposit with intrusion.The results show that both of them have the same source of material,and the gold bearing ore and the intrusive body are inherited in the rare earth elements.5?The study of fluid inclusions that it inclusions are distributed unevenly,and most of them are gas-liquid inclusions.The results show that the ore-forming temperature of gold deposits is relatively low.The characteristics of hydrogen and oxygen isotopes indicate that the ore-forming fluid of the gold deposit is a magmatic origin,the results show that the deposit is related to magma.The sulfur isotopic characteristics indicate that the ore-forming fluid is derived from igneous sources,so the intrusive body is the source of ore-forming fluid.
