中文摘要: |
在新疆达尔布特构造带附近展开多元信息综合找矿时,以遥感方法为先导,采用ETM数据多光谱假彩色合成、主成分分析、HSI编码、边缘增强以及Crosta法蚀变矿物填图等技术,结合化探异常及地质综合分析,圈定找矿靶区;经过部分地表检查验证,新发现矿化点8处,主要位于达尔布特断裂带的下盘,矿化多与花岗闪长岩小岩体有关,突破了前人认为成矿主要位于该断裂带上盘的认识,为区内找矿提供了重要线索,并为研究成矿规律、完善成矿理论提供了有益证据. |
英文摘要: |
Ore prospecting along the Darbutetectonic belt,Xinjiang is guided by remote sensing techniques,such as ETM multi-spectral false color composites,principal component analysis,HSI coding,edge enhancement and'Crosta technique'for the alteration mineral mapping.Combined the geochemical anomalies and comprehensive geological analysis with the results obtained from the remote sensing techniques are used to locate ore prospecting targets.Through ground inspection 8 new mineralization occurrences are discovered.They are mainly situated in the lower plate of the Darbut Fault.Mineralization is generally related to small granodiorite bodies.Previously,the mineralization was considered to be mainly located at upper plate of the Darbut Fault.Result of this study show important clues for further ore prospecting in the area and provide useful evidences for summarizing and perfecting metallogenesis along the Darbut Structure Zone. |
