Application of airborne hyperspectral remote sensing technique to geological prospecting-Taken the Liuyuan area in Gansu Province as an example

摘要

The Liuyuan area in Gansu Province is an important part of the Beishan metallogenic belt, where many polymetallic deposits are developed. This paper studies the metallogenic conditions and setting in the Liuyuan area using airborne hyperspectral remote sensing technique, and constructs its structural framework. The result shows that the structural framework exerts a key control on gold deposits in this region. And we research locating model of typical gold deposits in an effort to construct gold metallogenic and prospecting models in the Liuyuan area. Furthermore, we utilize this metallogenic model to practice, three targets similar to the known gold deposits in altered mineral association and metallogenic setting were found. And geochemical surveys have validated two targets of three have gold anomalies.
