The spectral reflectance features of rocks and minerals are correlated with their composition,col-or,grain size and surface state.Different wall rocks,altered rocks and ores have their spectral reflectance features,which are very helpful for the explanation of remote sensing data and searching for mineral deposits by remote sensing.After the treatment of spectrum data and searching for mineral deposits by remote sensing.After the treatment of spectrum data of rocks and ores and physical and chemical parameters in the mathematical statistics,we analyzed the laboratorial spectrum dataand put forward better wave bands(520-590,650-710,730-760,770-860,1560-1760,2200 and 2300-2400nm) for distinguishing rocks and ores. 相似文献

油气资源的勘探和开发工作是以地震勘探方法为基础,其成功率低,从而促使非地震勘探寻找油气资源的研究方法问世。八十年代以来,油气理论研究不断深化,油气藏上方存在着微渗漏的理论得到广泛证实。油气藏烃类微渗漏必然引起地表物质发生变化:土壤吸附烃异常、红色岩层褪色、粘土矿化蚀变晕、碳酸盐矿化蚀变晕、放射性异常、地热异常和地植物异常。将油气藏的烃类微渗漏理论与岩矿光谱特征相结合,便成为利用遥感技术直接寻找油气资源的新方法。中国科学院、中国石油天然气总公司油气遥感科研队,1988年以来在新疆准噶尔和塔里木两盆地进行了航空细红分外光谱遥感寻找油气资源的试验研究,取得了重大进 相似文献

Airborne Shortwave Infrared Spectral Remote Sensing as a Direct Prospecting Method for Oil and Gas Resources 总被引:1,自引:0,他引:1
杨柏林 《中国地球化学学报》1994,13(2):156-164
The spectral characters of hydrocarbons in some oil-bearing strata and soil layers ouer oil and gas reservoirs in the Junggar Basin and northern Tarim Basin in Xinjng are compared with those of chemically pure hydrocarbons.The hydrocarbons are characterized by the bi-absorption at 2310nm and 2350nm.Hydrocarbon and radioactive anomalies in oil and gas terrains are found much more widespread than carbonate alterations.Based on the spectra of heavy hydrocarbons related to oil between 2270nm and 2460nm and refined data treatme nt, remote sensing may hold encouraging promise as a directly prospecting technique for oil and gas resources. 相似文献
