中文摘要: |
白杨河地区地处新疆雪米斯坦火山岩带西段,是中国重要的铀多金属成矿区,在以往的地质勘查工作中,积累了丰富的研究成果和地质资料。本文利用白杨河地区已有的物探、化探、遥感等多元地学数据,开展了找矿信息二次挖掘和综合找矿应用研究。在航空高光谱遥感蚀变信息提取、基于地球化学元素序结构分析的化探异常信息提取、航磁和航放数据处理与解译推断的基础上,通过多元地学信息的集成和综合地质分析,进行成矿地质研究和找矿预测。研究表明,采用新的技术思路和技术方法开展地学数据的二次挖掘,可以获取更丰富的地质信息,对促进新一轮地质找矿工作具有重要的指导意义。 |
英文摘要: |
Baiyanghe area is located in the western part of the Xuemisitan volcanic rock belt in Xinjiang, and is an important uranium polymetallic metallogenic region in China. In the past geological exploration work, it has accumulated rich research results and geological data. This paper uses the existing geophysical, geochemical and remote sensing data in Baiyanghe area to carry out the secondary mining of prospecting information and comprehensive prospecting application. Based on the extraction of aerial hyperspectral alteration information, the extraction of geochemical anomaly information based on the analysis of geochemical element sequence structure, the processing and interpretation of aeromagnetic and airborne radiometric data, metallogenic geological research and prospecting prediction are carried out by the integration and comprehensive geological analysis of multiple geological information. The research shows that using new technical ideas and methods to carry out secondary mining of geological data can obtain more abundant geological information, which has important guiding significance for promoting a new round of geological prospecting. |
