遥感技术在青海省哈得尔甘地区找矿应用研究

A Research on Prospecting Application of Remote Sensing Technology in Hadzhan Region of Qinghai Province

主要运用美国landsat7(ETM+)多光谱数据在青海哈得尔甘地区提取蚀变信息,同时运用全色波段作为图像融合以及地质解译辅助数据,根据遥感提取的蚀变信息和异常特征进行找矿预测研究和圈定异常区,然后依据野外实地异常查证,为哈得尔甘地区及其他地区的找矿工作提供较好的参考价值。

With the continuous development of modern surveying and mapping remote sensing technology,it has been integrated into the planning,production and management of all walks of life,especially in the geological exploration and mining industry.This paper mainly uses the US landsat7 data(ETM+)multi-spectral data,ETM+multi-band data to extract the alteration information in the Hadzhan region of Qinghai.It uses the panchromatic band as the image fusion and geological interpretation auxiliary data according to the remote sensing extraction alteration.Information and anomalous characteristics are used to conduct ore prediction research and delineate anomalous areas.Then,it provides a good reference value for prospecting work in Hadzhan region and other areas based on field field anomaly verification.
