The Zhajiatongna survey area for gold deposits is located in Maduo Township, Qumarleb County, Southern Qinghai Province. On the basis of regional geological investigations, regional stream -sediment geochemical surveys at scales of 1∶200 000 and 1∶50 000 have been carried out in this district. The results show abundant of elements such as Au, As, Sb, Cu, Zn, Hg, Co, Ni, Ti, Li, SiO₂ , Fe₂O₃ and Na₂O (or oxide), especially Au, As, and Sb elements exhibit high background values or local anomalies. Verification of these anomalies suggests that there are gold ore bodies and some other similar local anomalies in this area, indicating their relationship with mineralization. In addition, a deep-penetrating geochemical exploration technique of electrochemical measurement was applied in this area to illuminate the three- dimensional distribution of the ore-forming elements and to help analyze the regional prospecting potential.
