摘要:
小沟里金矿区出露的红岭山组上岩段与中岩段呈整合接触，二者间形成了挤压构造破碎带，该破碎带为主要控矿构造，也为矿（化）体的主要赋矿层位。根据矿体成群、成带的分布特点，依次可将矿区分为北、中、南3个矿带。1-3号矿体位于北矿带，20-1号与22号矿体位于中矿带。3条矿体在走向与倾向上尚未尖灭封闭，因此认为其在走向及深部具有良好的找矿潜力，根据矿体赋存特征，圈定3处找矿靶区。通过工程验证，3处找矿靶区均探获矿（化）体，表明小沟里金矿区深部具有良好的找矿前景。

Abstract:
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.
