| 中文摘要: |
| 西藏玛那国地区处于班公湖—怒江成矿带西段,成矿层位为上白垩统竟柱山组砂岩。利用WorldView-2高分辨率遥感数据在玛那国地区开展1∶1万岩性—构造解译,重点进行了成矿层位的追索解译,结合Aster数据提取的遥感蚀变异常信息,野外查证发现玛那国地区存在铜、铁两种矿化。综合分析玛那国地区的矿化特征、成矿地质条件和控矿因素,建立了找矿标志,圈定铜银矿、铁金矿的找矿有利地段,为玛那国地区进一步的找矿工作提供了线索。 |
| 英文摘要: |
| The Managuo area is located in the western part of the Bangong Lake - Nu River metallogenic belt in Tibet, the host strata is the sandstone of Upper Cretaceous Jingzhushan Formation. Using the WorldView-2 high resolution remote sensing data in Managuo area, the lithology and structural interpretation were conducted in the scale of 1∶10000, the key is to delineate the ore-bearing strata. In combination of the alteration information interpreted from the Aster satellite data, the copper and iron mineralization spots were found by the field check in Managuo area. Based on comprehensive analysis of mineralization characteristics, metallogenic geological conditions and ore-controlling factors, the prospecting criteria was established and favorable targets for copper, silver, iron and gold prospecting were delineated, which provide prospecting clues for further exploration in Managuo area. |
