| 中文摘要: |
| 294地区位于内蒙古中部地槽褶皱系宝音图隆起北东端,是重要的多金属成矿区。研究工作运用遥感技术,结合野外调查资料,对该区围岩蚀变异常信息进行了提取和分析。结果显示,铁染、羟基蚀变异常遥感信息分布于断裂构造的旁侧,以NE向、近EW向呈带状分布,并且与已知矿床(点)具有很好的吻合性。从而证明蚀变异常遥感信息能够指示出成矿的潜在部位,对进一步找矿勘查具有指导作用。 |
| 英文摘要: |
| 294 area is located at northeast end of Bayitu uplift of the middle Inner Mongolian geosyncline fold system and is an important multi-metal metallogenic area. Combined with field work, the authors use remote sensing technique to extract and analyze the wall rock alteration and mineralization information of the area. The results show that iron stain and hydroxyl-bearing minerals are distributed in NE and nearly EW zones along fractures and well coincided with the known mineral deposits. It is indicated that the remote sensing alteration information can be used to locate potential position of mineral deposit thus important to ore exploration. |
