The upper and middle rock sections in Honglingshan Formation outcropping from Xiaogouli Gold District are in conformable contact.The two form compressive structural fracture zone,the main ore-controlling structure as well as the main ore-hosting strata of ore(mineralized) body.Since the ore bodies are distributed in groups and zones,the district can be pided into 3 ore zones,namely the north,middle and south.The 1-3 ore body is distributed in the north,20-1 and 22 ore bodies are distributed in the middle.The 3 ore bodies are not yet pinching out and concealed deep in strike and inclination.It is therefore considered that there are good prospecting potentials along the strike and on the deep part.According to the ore occurrence characteristcs,3 prospecting targets are delineated.Verified by engineering,ore(mineralized) bodies are detected in all 3 prospecting targets,indicating good prospecting potentials deep in Xiaogouli Gold District.
