| 中文摘要: |
| 文章采用多源遥感技术,以ETM+和WorldView-2数据为遥感数据源,从不同的层面,对研究区内与夕卡岩型矿床有关的围岩、侵入体及其接触带,进行遥感地质信息提取及其分析研究。圈定拉陵郭勒河东地区为遥感找矿靶区。经野外验证,确定在WorldView-2影像上提取的异常地质体为夕卡岩带,该带磁铁矿化现象非常明显,经样品检测,Fe含量已达到工业品位。通过研究,作者对夕卡岩型矿床的遥感找矿标志进行了归纳,总结其遥感地质矿产调查技术方法,以期为其他地区夕卡岩型矿床调查提供参考。 |
| 英文摘要: |
| The remote sensing geological information including the intrusion, surrounding rocks and contact zone related to skarn type mineralization were extracted and analzed based on ETM+ and WorldView-2 remote sensing data sources, by using the multi-sources remote sensing technology. The Lalingzaohuo area is delineated as remote sensing prospecting target area and verified by the fieldwork.It is determined that the abnormal geological body extracted on the WorldView-2 image actually is the skarn zone.The magnetite alteration is very obvious, the iron content has reached its economic grade by the sample analysis. Then the remote sensing prospecting criteria for the skarn type mineralization was summarized, as well as remote sensing technology and methods in geological survey and mineral resources exploration, which provide valuable references for prospecting the skarn type ore deposit in other areas. |
