摘要
对研究区内金矿岩双桥山群的4336件岩石密度数据的统计分布、空间制图分析,得到岩石密度参数的地质制图,发现双桥山群岩石密度为偏态分布,推测岩石密度的增高可能是变质作用或成矿作用增强的反映,区内主要岩金矿床均分布在密度高异常区内,因此认为高密度异常区或重力正异常区,是区内岩金矿床的找矿远景区。
Statistics and mapping analyses have been done for rock density data of 4336 samples from Shuangqiaoshan group, which is gold source bed in the Jiuling-Gaotaishan metallogenic area, Jiangxi Province, eastern China. It is concluded that geological mapping of rock density can improve the information and precision of geological documents. The raising of density value and the skewness distribution of density data of source bed suggested that the higher density anomaly and positive gravity anomaly would be prospecting area for gold deposits.
