摘要
本文从岩石和矿物成分、粒度、颜色和表面状态探讨它们与反射光谱特征的关系,并研究了某些铜铁矿床的围岩、蚀变岩和矿石的反射光谱特征。对反射光谱数据和物理化学参数进行数理统计分析后,提出区分岩石和矿石较好的工作波段。
The reflective spectrum features of rocks and ores are correlated with their composition, colour, grain size and surface state. Different wall rocks, altered rocks and ores have their respective spectrum 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 of rocks and ores and physical and chemical parameters in the mathematical statistics, we analyzed the laboratorial spectrum data and put forward better wave bands (520-590, 650-710, 730-760, 770-860, 1560-1760, 2200 and 2300-2400 nm) for distinguishing rocks and ores.
