| 中文摘要: |
| 青海哈龙尔玛地区位于东昆仑造山带,该带是中国西部重要的矿产资源基地,成矿类型复杂,矿种丰富多样。工作区紧邻热水钼矿、哈陇休玛多金属矿及那更银矿,区位成矿条件优越。通过综合分析地球物理特征和成矿地质条件,推测该区深部存在隐伏矿化体。经过激电中梯剖面测量和化探异常查证,低阻高极化激电异常显示面状异常特征,与地表发现的黄铁绢英岩化带套合较好,异常规模大、强度高;对低阻高极化异常地段实施槽探揭露,圈出了铜钼钨矿体。采用激发极化法在该区寻找铜钼钨矿是有效的,为该区下一步找矿部署和目标靶区提供了依据。 |
| 英文摘要: |
| Halongerma area is located in east Kunlun organic belt. The belt is an important mineral resources base of the west China with complex metallogenic processes and multi-ore types. The study area is near Reshui Mo deposit, Halongxiuma polymetallic deposit and Nageng Ag deposit. Comprehensive analysis of geophysical characteristics and metallogenic conditions show that hidden mineralized bodies may occur to depth of the study area. Mid ladder profile measurement is conducted and large planar low resistivity and high polarization IP anomaly lineated. Checked by geochemical anomaly the geophysical anomaly fits whell the surgical phyllic alterat ion zone. Trenches are rigged at the anomaly and Cu-Mo-W ore bodies located thus IP polarization is effective for targeting polymetallic deposit in future exploration in the area. |
