| 中文摘要: |
| 拉陵灶火铜多金属矿床位于伯喀里克—香日德印支期Au-Pb-Zn-Mo-石墨-萤石(Cu、稀有、稀土)成矿带西段,矽卡岩型矿床。为扩大矿区西侧新圈定的金、铜矿化体规模,对缓磁异常区域开展了1∶2000高精度磁法测量,结果表明,1∶2000磁测能很好地显示低缓磁异常—控矿接触带。新发现4处弱磁异常,新圈定矿(化)体8处、矽卡岩7条。能精确圈定含矿矽卡岩带走向及位置,具有良好的找矿效果。 |
| 英文摘要: |
| Lalingzaohuo copper-polymetallic deposit is located in the west section of Au-Pb-Zn-Mo-graphite-fluorite (Cu, rare elements and rare earth) metallogenic belt in the Indosinian period of Bokalike-Xiangride, is a skarn type deposit. In order to enlarge the scale of the newly delineated gold and copper ore bodies on the west side of the mining area, 1∶2000 high-precision magnetic survey was carried out in the low-gradient magnetic anomaly area. The results showed that the 1∶2000 area magnetic survey can well display the small-amplitude low-gradient magnetic anomaly and the ore-controlling contact zone. Under survey, 4 weak magnetic anomalies, 8 ore (mineralized) bodies and 7 skarn anomalies were newly werediscovered and delineated for the first time. It also is found that 1∶2000 area magnetic survey can accurately delineate the strike and location of the ore-bearing skarn beltand has achieved excellent ore-prospecting effect. |
