摘要

The regional geology in Toutanzi area of Huixian County is introduced. The soil geochemical survey of scale 1: 25 000 determined 11 pieces of gold anomaly of soil, which show that the distribution of soil halos is consistent with the spreading direction of structures, the selectivity of halos to strata is not obvious. The study reveals that the gold mineralization is controlled by the trinity of structures, hydrothermal fluids and stratigraphic lithology, particularly, the fault is necessary.
