Outline
The study area is located in the Dongxiang Volcanic Basin in the middle part of the Qin-Hang mineralization belt, where several gold-lead-zinc (Au-Pb-Zn)-based mineralization and mineralization sites have been detected. Based on the principle of “from the known to the unknown”, combineing the results of physical and chemical exploration, such as the excitation middle gradient measurement and soil geochemistry, the characteristics of the combined parameters of the gamma spectra of Qiaoxi (HS-1) and Oujia (HS-2) was compared and analyzed, it was concluded that the anomaly centers of the characteristic parameters of the ground γ-ray were more concentrated than those of the anomalies obtained from soil geochemistry measurements. It was believed that the anomaly centers of the ground γ-ray energy spectral parameters were more concentrated than those of the soil geochemical measurements, and the F parameters were positively correlated with the anomalies in the K alteration zone, and the N parameters were positively correlated with the anomalies in the Na chemotaxis zone; and it was hypothesized that the HS-2 area has a relatively good prospect of gold polymetallic prospecting. The results provides a new theoretical basis for unit and super-unit delineation of volcanic areas, and proves that in practical work, the geological situation and characteristics of the area was comprehensively analyzed, and the appropriate combination of parameters was determine to indirectly explain the nature or cause of mineralized alteration in the area, which is more instructive than the traditional single-element spectral study.
