| 摘 要： | 矿体产于白垩纪马头窝单元（K1^7M^λπ）石英斑岩与石炭系上统空树河组三段二层（C2k^3-3）地层的石英砂岩、长石石英砂岩接触带上，或上述两类岩石的破碎带中，矿体与围岩界线常呈波状起伏，呈突变或渐变接触。矿区围岩蚀变明显，有进一步找矿的前景。

| Abstract: | The ore bodies are on the contact between Cretaceous Matouwo quartz porphyry （ K1^7M^λπ） and Upper Carboniferous Kongshuhe Formation Member 3 Horizon 2 （ C2k^3 -3 ） silicarenite and felsic sandstone or in the fracture zone of rocks mentioned above. The boundary between ore body and wall rock is wave - like, abrupt or progressive contact. The wall rock alteration is evident and the prospecting potentiality is good. |
