摘要
衡阳盆地形成受基底构造控制,沉积厚度大,"盆""岭"反差大,盖层伸展构造为矿液运移提供了通道和储集空间;盆地四周和盆内不同期次的岩浆热液活动为成矿提供了热源和物源;NE向、NW向、E-W向基底构造交汇,控制不同矿化类型呈带状分布。本文分析了衡阳盆地矿产空间分布规律、成矿地质条件,阐述了典型矿床特征和找矿标志,指出了找矿远景区域。
The formation of Hengyang basin with large sediment thickness and contrasting of ＂basin＂ and ＂range＂ is controlled by basement structure, while the extensional movement of caprock can provide ore fluid mi- gration channels and reservoir space. The different stages magmatic hydrothermal movements in the base and sur- round areas can provide heat source and ore-forming materials. NE-, NW- and EW-trending basement structures intersection control different types of mineralization zonal distribution. Mineral spatial distribution law, ore-forming geological conditions, typical ore deposit characteristics, prospecting criteria and prospecting areas are summarized in this paper.
