槐树坪金矿区位于熊耳山断隆和谭头-嵩县新生代断陷盆地之间,研究表明,中-新生代缓倾斜滑脱拆离断层的次级缓倾斜断裂为槐树坪金矿成矿提供了良好的赋矿空间。矿区揭露的燕山期花岗斑岩体(或隐伏斑岩体)是含矿热液的提供者,含矿热液在适宜的物理化学条件下,沿矿脉或断裂上升至次级缓倾斜断裂中沉淀且富集成矿,矿床规模已达大型。中-新生代缓倾斜滑脱拆离断层属区域大断裂,其次级缓倾斜断裂广泛发育在嵩县南部和洛宁等地区,是有利的赋矿空间,综上可见,缓倾斜次级断裂在区域上的找矿前景非常广阔。
槐樹坪金礦區位于熊耳山斷隆和譚頭-嵩縣新生代斷陷盆地之間,研究錶明,中-新生代緩傾斜滑脫拆離斷層的次級緩傾斜斷裂為槐樹坪金礦成礦提供瞭良好的賦礦空間。礦區揭露的燕山期花崗斑巖體(或隱伏斑巖體)是含礦熱液的提供者,含礦熱液在適宜的物理化學條件下,沿礦脈或斷裂上升至次級緩傾斜斷裂中沉澱且富集成礦,礦床規模已達大型。中-新生代緩傾斜滑脫拆離斷層屬區域大斷裂,其次級緩傾斜斷裂廣汎髮育在嵩縣南部和洛寧等地區,是有利的賦礦空間,綜上可見,緩傾斜次級斷裂在區域上的找礦前景非常廣闊。

Huaishuping gold area is located between the Xiong’er Mountain fault and the rift basin of Tantou-Songxian in Cenozoic,research shows that the secondary gentle-dipping faults of gentle dip slip-detachment fault in Meso-Cenozoic has provides the ore-hosting sites for ore-forming of the Huaishuping gold deposit.The Yanshan granite porphyry (or buried porphyry) which revealed has provided the ore-forming fluids.Hydrothermal along veins or fracture rise to secondary gentle-dipping faults and enrichment and mineralization of gold under optimal physical and chemical conditions.The scale of Huaishuping gold deposit has reached large size.The gentle dip slip-detachment fault in Meso-Cenozoic is regional faults and their secondary gentle-dipping faults are widely developed in the south of Songxian and Luoning and so on and offer space for enrichment of metallogenic materials.Comprehensive studies have shown that the secondary gentle-dipping faults on the regional prospecting are very wide.
