广宁某金矿床控矿构造特征及金矿赋存规律初步探讨

Preliminary discussion on ore controlling structural characteristics and occurrence law of gold deposit in Guangning

本区处于河台金矿田~新洲金矿田中部,位于东西向与北东向构造交接复合部位,发育一系列的北东向压扭性断裂,北北东向和南北向的张扭性断裂及北西向张性断裂。南北向及北东向断裂均有金矿(化)体产出,为区内的导矿及容矿构造。通过对区内主要构造与其次级断裂的空间上产出状态和性质等的地质研究,初步阐明了扬村金矿床的控矿构造地质特征,并探讨了金矿的地质特质及赋存规律。本区圈定多条破碎带蚀变岩型金工业矿体,金矿体均赋存于断裂破碎带中。

This area is located in the middle part of Hetai Gold Orefield^Xinzhou Gold Orefield,located at the junction of the east-west and north-east structural junctions,and developed a series of north-east compression-torsion faults,northnorth-east and south-north Of tensile torsional faults and northwestern tensile faults.Both the north-south and northeast faults have gold ore(chemical)bodies,which are the ore-guiding and ore-holding structures in the area.Through the geological research on the spatial output status and properties of the main structures and their secondary faults in the area,the geological characteristics of the ore-controlling structure of the Yangcun gold deposit were initially clarified,and the geological characteristics and occurrence rules of the gold deposit were discussed.A number of altered rock-type gold industrial ore bodies in the fracture zone are delineated in this area,and the gold ore bodies are all present in the fracture and fracture zone.
