摘要
马泉金矿床是受近EW向礼县-白云-山阳区域性深大断裂南支——礼县-洮坪断裂或层间挤压破碎带控制的中-低温热液矿床,目前已发现9个矿带。通过对其中四号矿带的勘查验证,对四号矿带的地质特征进行了重新认识和归纳总结。研究认为,矿带断裂构造十分发育,在矿区内发育的三条主要断裂构造严格控制着四号矿带的三条金矿体的空间展布及产出规模,找矿标志较多且明显,并认为,四号矿带之东西两侧延伸部位及其深部尚有一定的找矿潜力。
The Maquan gold deposit is a mesothermal to epithermal deposit controlled by near EW trending Lixian-Baiyun-shanyang regional deep rooted fracture Nanzi-Lixian-Taoping fracture or interlayer compressional fracture zone. Nine ore zones have been found until now, with No. 4 zone being testified by exploration. The geological characteristics was reviewed and summarized with a conclusion that there is still ore potential in the area.
