新疆西西尔塔克一带火山沉积型硼矿地质特征及成因浅析
Geological Characteristics and Cause of Formation of Volcanic Sedimentary Boron Deposits in the Xixiertake, Xinjiang

新疆东天山西西尔塔克一带硼矿是目前国内发现的少数火山沉积型硼矿床之一，该区硼矿均赋存在同一个含矿层位——上石炭统柳树沟组二段中，上石炭统柳树沟组二段至少存在4个以上喷发旋回，硼矿化主要发育在第二、三、四个喷发旋回。该区硼矿的形成与区内火山活动关系极为密切，是富含硼的火山活动的产物，区内硼矿矿石矿物主要为硅硼钙石。
The boron deposit in the Xixiertake area of Eastern Tianshan Mountains in Xinjiang is one of the few volcanic sedimentary boron deposits discovered in China. The boron ore deposits in this area all exist in the same ore bearing strata—two Period of Liusugou group of Upper Carboniferous, there are at least four eruption cycles in the upper Carboniferous two period of Liusugou group, boron mineralization is mainly developed in the second, third and fourth eruptive cycles. The formation of boron ore in this area is closely related to volcanic activity in the area, it’s a product of boron-rich volcanic activity, the boron ore minerals in the area are mainly silicolites.
