某碱性花岗岩稀有稀土矿床(801矿),是吉林省地质局区测队1975年进行1∶20万区域地质调查时通过放射性测量发现的.该矿是国内首次发现的一种新类型工业矿床,矿石品位富,稀有稀土元素种类多,矿化深度大.笔者研究了矿床中稀有稀土元素矿物及其地球化学特征,并运用数学方法统计了元素的空间分布特点及各成分间的关系,现简述如下.矿区及矿床地质简述矿区位于某隆起带,东西向压性断裂及两条华夏式大断裂之间.区内局部出露古生代海相砂页岩及火山岩,大面积出露中生代火山碎屑岩,主要为侏罗系呼日格组、付家洼组、宝石组等一套
A basic granite rare earth deposit (801 mine) was discovered by radioactive measurements when the Geological Bureau of Jilin Province carried out 1: 200,000 regional geological survey in 1975. This mine is the first new type of industrial deposit discovered in China , Rich ore grade, rare rare earth element variety and deep mineralization depth.The authors studied the rare earth element minerals and their geochemical characteristics in the deposit, and used the mathematical method to calculate the spatial distribution characteristics and the relationship among the elements Briefly described as follows: Brief Description of Geology of Mines and Deposits The mine is located between a uplift belt, east-west compression fracture and two Huaxia-type large faults.The Paleozoic marine sand shale and volcanic rocks are partially exposed in the area, revealing a large area of Mesozoic Pyroclastic rocks, mainly for the Jurassic Hugh grid group, Fu Jia Wa group, a set of gems
