摘要
利用"全国区域地球化学勘查数据库"等全国性基础地质数据库数据,对全国分区进行金成矿统计预测;根据信息量异常分布,结合大地构造背景、主要控矿因素等,将全国划分为64个金矿找矿远景区;并用信息量转换法估算全国1000m以浅金矿资源总量约为43500t,资源潜力36500t。
Based on the national basic geological database, such as China Regional Geochemical Survey Data Base etc. , Statistic prediction of potential gold resource of China was carried out in term of gold metallogenic provinces. According to distribution of the information content anomaly, geotectonic background and the main ore-control factors, sixty four gold prospects were identified in China. Then information content transference method is adopted to estimate total gold resource of 43500 t and potential gold resource of 36 500 t respectively to depth of 1 000 m beneath the surface.
