利用高分遥感技术发现西昆仑黑恰铁矿矿化带及其地质意义

西昆仑地区自然地理条件恶劣,交通条件极差,导致该地区地质工作程度较低。在西昆仑艰险地区充分利用高分遥感数据的优势开展遥感调查,通过对研究区成矿地质条件分析,建立矿化带高分遥感解译标志和高分铁染异常提取,辅以适当的野外查证,黑恰铁矿矿化带的发现为地质找矿提供新的线索。根据其遥感地质特征建立遥感地质找矿模型,为今后在西昆仑成矿带上寻找类似矿产提供遥感依据。该矿化带是北侧黑黑孜江干铁多金属矿床向东南方向的延伸,其成矿特征与西昆仑已经发现的一系列层控碳酸盐岩型的铁-铜、铅、锌-金矿床的成矿特征相似,沿东南方向具有较大找矿潜力,有望形成有前景的铁多金属矿床。

The Discovery of Heiqia Iron Mineralization Belt in West Kunlun by High Resolution Remote Sensing Technology and Its Geological Significance

Because of the harsh natural conditions and poor traffic conditions in West Kunlun, less geological work has been conducted in this area. This paper makes use of the high resolution remote sensing data in light of its advantages to carry out remote sensing survey, first analyzed the metallogenic geological conditions in the study area, and then established the interpretation marks of high resolution remote sensing in the mineralized zone. Besides, the ferric contamination anomaly has been extracted. Combining with field survey, Heiqia iron mineralization was found, which will provide new clues in terms of geological prospecting. According to its geological characteristics of remote sensing, a remote sensing geological prospecting model has been established and will provide the basis for future remote sensing metallogenic belt in West Kunlun to find similar minerals. The mineralized zone is an extension of the iron polymetallic deposits in the southeast; it is similar with many Fe-Cu-Pb-Zn-Au mineral deposits discovered in West Kunlun. There is greater prospecting potential toward southeast area, and the Heiqia iron mineralization is expected to become an iron polymetallic mineral deposit.
