### Case Study on Daiyinzhang Gold Deposit  
The Daiyinzhang gold polymetallic deposit is located in the midwestern section of Wutaishan area from Shanxi, in the middle-high mountainous area. The terrain in the area is high in the east and low in the west, with developed valleys and severe topography, where exposed strata mainly consist of the chlorite schist and sericite schist of the Baizhiyan Formation of the Neoarchean Wutai Group. The alteration phenomena of pyrite mineralization, silicification, tourmaline, sericitization, and carbonation are obvious. The intrusive

Figure 4: Results obtained by employing the DL-CHIM method over 210 gold deposit from Xinjiang, China. 1—Quaternary System Holocene; 2—Quaternary System Pleistocene; 3—Gold ore body; (**a**) Anion anomalies of Au (Anode extraction); (**b**) Cation anomalies of Au (Cathode extraction); (c) geological base map [13].  
rocks are mainly dominated by Wutai plagioclase granite and Lvliang metamorphic dia-base [35; 36]. The ore body, with strike length 450 m, has a burial depth of 0 m to 558 m and a thickness of 0.53 m to 2.44 m; its Au average grade is 2.97 g/t. It can be seen from Figure 5 that the cation anomalies of Au mainly occur at measurement points from 11 to 18, and the anomalous values are in the range from 6.21 ppb to 11.21 ppb, with an average intensity of 8.83 ppb, which basically corresponds to the ore bodies near the surface; in addition, the extreme values of the anomalies are relatively continuous, which is basically consistent with the distribution of gold ore bodies. The anion anomalies of Au occur at measurement points from 5 to 11, and the anomalous values are in the range from 4.65 ppb to 16.98 ppb, with an average intensity of 9.47 ppb, corresponding to the buried ore bodies. In the geochemical soil survey, the soil anomalies of Au occur at measurement points from 15 to 19, and the anomalous values are in the range from 4.86 ppb to 481.62 ppb, with an average intensity of 121.02 ppb, which has some displacement with the ore bodies near the surface; for buried ore bodies, the soil anomalies of Au are weak, basically showing the background characteristics. In general, in the thick transported covered terrains (measurement points from 1 to 10), the geochemical soil survey shows only background characteristics; however, DL-CHIM method shows obvious anion and cation anomalies of Au at measurement points for 5, 6 and 8. The analytical results of this field work are tabulated in Table 3.
