摘要
涞源-易县地区是河北省铜钼金多金属重点勘查区,以往金矿勘查成果表明,金矿床(点)空间分布主要集中于阜平变质核杂岩剥离滑脱断裂带与北西向韧性剪切带的交叉部位。本文通过对易县柴厂-孔格庄金矿田研究,认为随变质核杂岩的形成,主剥离断层成为良好的导矿和储矿空间,北西向断裂叠加和改造北西向韧性剪切带,诱导了深源含矿物质的上升,在剥离滑脱断裂体系的不同部位,形成不同类型矿床。通过总结柴厂-孔格庄金矿田成矿模式,讨论了涞源-易县地区找矿模型,提出了涞源-易县地区金矿主要找矿类型及找矿方向。
Laiyuan-Yixian area is a key exploration area of Cu-Mu-Au multi metals in Hebei Province. Previous exploration results of gold deposit show that the spatial distribution of gold deposits（points） mainly concentrated in the cross area of the Fuping metamorphic core complex stripping detachment fault zone and the northwest ductile shear zone.This paper, based on the research of Caichang- Konggezhuang gold ore field of Yixian, proposes that the main detachment fault should be a good space of ore conducting and mineral storage with the formation of the metamorphic core complex. Northwest faults superposited and reformed the northwest ductile shear zone,which conducted the rise of deep source containing minerals then formed the different types of ore deposits in the different parts of the stripping detachment fault system.Through summarizing the metallogenic model of Caichang- Konggezhuang gold ore field, this paper discussed the prospecting model in Laiyuan-Yixian area and presented the main prospecting type and the prospecting direction of gold ore in Laiyuan-Yixian area.
