A comprehensive study of the surface rock spectrum test:A case study of Lingqiu area in Shanxi Province

Abstract
Combined with the regional geological background and starting with the measured spectrums of rocks and minerals, the author first made pretreatment of the measured spectrum and, on such a basis, established the measured spectral library. With the rock and mineral spectral characteristics theory as a guide and the spectral characteristics of the measured sample as the reference, an analysis of different mineral spectrum has a characteristic spectrum and diagnostic fault spectrum; through the rock and mineral identification of the field rock samples, the multiple linear regression method is used for inversion of oxide content from the measured spectrum. The result is reliable. Within the study area oxides are interpolated by Kriging interpolation method, the fractal theory is used for ex-traction of oxide anomaly; with the abnormal superposition method, the anomalous concentration area in the study area is extracted; combined with geochemical anomalies and geological background, 31 ore-searching prospective areas are delineated in the study area.
