| 中文摘要: |
| 在甘肃夹山地区开展1:5万水系沉积物测量,通过水系沉积物样品分析结果的数理统计,从地球化学参数特征、元素组合特征、元素区域分布规律及异常特征等方面,对夹山地区地球化学特征进行了分析研究。结果表明,该区主要成矿元素异常受古元古界-新太古界敦煌岩群和华力西期岩浆-构造成矿体系控制,结合区内矿产分布及成矿地质特征,圈定了4处多金属矿找矿远景区,主攻矿种为金多金属、铜多金属、稀有金属。 |
| 英文摘要: |
| Stream sediment survey at scale 1:50000 was carried out in Jiashan area of Gansu province. Samples were collected and analyzed. Mathmatic statistics was conducted on the analysis. Geochemical characteristics is studied based on geochemical parameter, element combination, regional distribution of the elements and anomaly distribution. Major ore element anomalies are generally controlled by Palaeo-Proterozoic-Neo-Archean Dunhuang group and Hercynian magmatic-tectonic metallogenic system. Four polymetallic ore prospecting targets are located directing mainly to Au-polymetallic deposit, Cu-polymetallic deposit and rare metal deposit. |
