摘要
马滑沟金矿产于黄陵断穹西南部中、晚元古代岩浆岩与中元古界崆岭群接触带附近,金矿体多分布于FAuⅠ、FAuⅡ脆—韧性剪切带中,矿石自然类型有蚀变塑性变质岩型、石英细脉型、碎裂蚀变岩型,矿石工业类型为金硫化物—脉石英矿石,矿床成因类型为含金蚀变构造岩型矿床。建议今后工作从本矿床的深部及外围着手,逐部扩大勘查范围,以求本地区金矿勘查的突破。
Mahuagou gold deposit originated from southwest Huangling fault arch in late proterozoic magmatic rocks and Mesoproterozoic Kongling group near the contact zone. Gold ore bodies are distributed in FAu I and FAu II brittle -ductile shear zone. Natural types of ore have altered the plastic metamorphic rock type, quartz veinlet type and cataclastic altered rock type. Industrial type is gold sulfide-vein quartz ore. It is suggested that from the deep and peripheral of this deposit, the authors will expand the exploration scope, in order to have breakthrough of gold exploration in this region.
