Red Edge Shift and its Implication for Buried Ore Prospecting a Case Study of Shujigou Copper Mine, Liaoning, P.R.China
It is difficult for ore prospecting by conventional methods of geologic mapping and geophysical or geochemical methods in highly vegetated terrain. High resolution spectral measurement is an excellent tool. In this paper, the reflectance spectra of oak leaves and larch leaves in Shujigou Copper Mine, P.R. China, were measured by ASD Fieldspec®3 portable spectroradiometer and red edge positions are obtained by derivative method. The results indicate that the “blue shift” of foliage of both species is spatially well in accordance with the ore bodies, despite of the ore vein buried or not and the depth of ore-bury. The research provides the theoretical basis for the ore exploration in vegetated terrain by hyperspectral remote sensing method.
