| 摘 要： | 本文为关于矿产资源预测新参数———蚀变遥感异常系列论文的第一篇。文中论述了蚀变遥感异常信息提取的地质依据和波谱前提,报道了东天山大东沟至赤湖地区两万余平方公里遥感蚀变异常提取及部分异常点的实地查证结果。区内有已知矿床、矿(化)点71个,所取得的遥感异常与其中61个互洽,吻合率达85.9%,且与已知矿床的吻合率为100%。经首批地面查证,扩大了一处已知矿点的找矿范围。文中定义了某些相关的新技术术语。 |
| 关 键 词： | 蚀变遥感异常 蚀变异常 铁染异常 遥感异常 |

| Abstract: | This is the first paper in the serial articles on the new parameter for the prediction of the mineral resources-alteration RS anomalies. The geological basis and the spectral presupposition for the alteration anomalies are discussed. The result of extracting alteration anomalies in an area of more than 20 000 square kilometers within East Tianshan Mountains and the result of the in-situ investigation of some anomalies are reported. Among the 71 known deposits or mineralization spots in this area, 61 have the corresponding alteration anomalies. The coincidence coefficient is as high as 85.9%. Some new related terms are defined. |
