【摘要】 西藏东部地区复杂的地质构造地貌条件使得实地踏勘工作难度很大,因此在研究中利用遥感影像来进行蚀变异常区域的解译。在解译过程中,针对于热液蚀变型矿床引入TM数据的热红外波段和比值分析进行RGB合成的方法。解译结果显示:在藏东特殊的地质成因下,应用热红外波段进行蚀变异常解译具有可行性。更多还原

【Abstract】 The complicated tectonics and topography of the east Tibet make geological survey on the spot very difficult and remote sensing images are used to interprete anomaly areas there.RGB combination of thermal infrared band and ratio analysis of TM image is introduced to study on the hydrothermal alteration ore deposits in east Tibet.The results show feasibility of the infrared band for interpretation of hydrothermal alteration anomalies in east Tibet.更多还原
