摘要
ASTER遥感数据因波段范围宽、波段多,在蚀变异常提取与矿产勘探中有较好的应用前景.据金属矿床常见蚀变矿物光谱特征与ASTER数据波段设置特点,提出硅酸盐铁、Fe^(2+)、白云石等提取的光谱指数.在此基础上研究该数据大气校正、干扰剔除等数据处理技术方法,提出了异常提取技术流程与步骤,在新疆东天山天湖铁矿区进行了试验研究,将矿物提取结果与地质图对比分析,表明提取结果与数据处理技术流程较可靠.
ASTER. Remote sensing data have a good prospect in the abnormal alteration mineral extraction and ： exploration as a result of wide-band range and multi-band. According to the metallic mineral deposits commonly altered spectral characteristics and the characteristics of the band Of ASTER, the Ferrous silicates ,Ferrous iron Fe^2＋,dolomite, and other mineral extraction of the specmLm index were made. On this basis, the Atmospheric correction and removing inierference were studied. The unusual extraction technology processes and procedures were built. Tianhu Iron Ore in Xinjiang Tianshan Mountain were study; the results showed that extract and process data-processing techniques are more reliable.
