| 中文摘要: |
| 黑沙山南铁多金属矿位于青海省柴达木盆地南缘,属祁漫塔格—都兰华力西期成矿带东段,野马泉—开木琪河华力西期成矿亚段东段,具有较好的区域成矿地质背景。预查区位于青海省格尔木市西北部,覆盖面积较广。在前人工作的基础上,利用1∶1万高精度磁测方法,在预查区内圈出了M1～M5处磁异常,重点对 M1和M3异常进行了验证,在M1发现了V1～V5矿体, 将M3划分为9个子异常,在其中两个子异常中发现了Ⅵ号矿体,该区具有较好的找矿前景。 |
| 英文摘要: |
| The Heishashannan iron polymetallic deposit is located in the southern Qaidam basin of Qinghai, occurs in the eastern part of Variscan Qimantage-Doulan metallogenic belt, and eastern section of the Variscan Yemaquan-Kaimuqihe sub-mineralization zone. There is a favorable ore-forming geological background in the deposit area. The reconnaissance area is located in the northwestern part of Qinghai Province with widely covering area. On the basis of the previous work, the high precision magnetic survey was conducted by the use of 1∶10,000 scale, and five magnetic anomalies, i.e.,from M1 to M5, were outlined. Follow-up exploration focuses on M1 and M3 anomalies. And five iron orebodies were discovered within the M1 anomaly, i.e., VI toV5 orebody. The M3 magnetic anomaly is divided into nine sub-anomalies,and two orebodies were discovered in the two sub-anomalies. It indicates there is great potential for discovering the large-sized iron polymetallic deposit in the prospecting area. |
