322矿田主控因素新说

３２２地区北东向断裂构造具压剪性，左行左滑的特点，它对３２２矿田的定位具有明显的控制作用，是铀矿作用的主控因素，由于北东向断层的左行走滑，在丰州一带生成拉盆地，北东向断裂，丰州盆地的形成，演化，控制了矿田内各矿床的形成。     

试论华北地台西北缘多金属硫铁矿控矿因素

裂谷系-克拉通边缘断陷带-同生断裂-断陷盆地是华北地台西北缘元古宙层控型多金属硫铁矿最重要的控矿格局。矿床具有明显的层控、时控和岩控特征。枢扭带线型构造控制一、二级盆地及矿带、矿田的空间展布;同生断裂控制有硫化物堆积的三级盆地;伸展构造在横向上的互补作用导致岩(矿)层走向上的伸、缩变化;低补偿与超补偿沉积界面为硫化物沉淀提供了有利的物理、化学场;同沉积火成活动为含矿热液的对流循环提供了足够的能量。深入研究并正确认识上述控矿因素的控矿作用对于指导该区乃至同类矿床的普查找矿和成矿预测具有重要意义。

Source of ore-forming material for the Huangtuliang gold deposit,Hebei Province and ore prospecting in the deep periphery

The Huangtuliang gold deposit is characterized by its wide and large ore belt, stable extension and closely spaced orebodies. Unfortunately, no orebody was found by deep drilling. As a result, ore prospecting in this region was once put into dilemma. Detailed analysis of ore-forming and ore-controlling structures in the mining district by the authors has revealed that the ore-forming and ore-controlling structure in this mining district is a steeply dipping （85°-110°/∠70°-85° N-NNE）, spade-shaped ductile shear zone, and the ore-controlling structures are a series of nearly erected second-ordered faults which are developed in the upper part of the ductile shear zone, inter-secting with the ductile shear zone. Deep cutting of the ductile shear zone made it possible the ascending of ore fluids from the mantle plume at depth and these ore fluids would migrate upwards along the ductile shear zone under certain temperature and pressure conditions. Along their ascending path, the ore fluids would extract ore-forming elements from the country rocks and the extracted ore-forming elements would be deposited as ores in the hang- ing-wall second-ordered faults. The reason why no orebody was found in early prospecting at depth is that north- ward-dipping drilling in the southern part of the shear zone extended so deeply as to be beneath the shear zone. Only shallow-level orebodies could be found by southward-dipping drilling practice in the northern part of the shear zone. The location where deep-seated orebodies occurred shifted northwards and the orebodies occurred at greater depth. Therefore, it is natural that no orebody could be found when drill core passed through the shear zone. After the ore-forming and ore-controlling structures were well understood, the focus of ore prospecting was placed on the deep-level, northward-penetrating veins. In this way a number of new blind orebodies of great thickness have been found. On the basis of research development in the mining district, a prospecting plan has been made

新疆西滩金矿控矿构造初探

西滩金矿属少硫化物石英脉型金矿。通过野外调研,发现该矿床的空间定位、脉体的分布格局、矿体的赋存规律都与秋格明塔什韧性剪切带及其南界苦水大断裂的多次活动和由它派生的多序次构造有关。笔者认为西滩金矿床的控矿构造属帚状构造。根据这一认识布置的几条物探剖面中已发现了几个有意义的异常。因此,本文论述的控矿构造可作为区内金矿预测的依据之一。
