摘要
现代造山带研究成果表明,造山带古海洋学这一新学科即将形成。造山带古海洋学应含下述6个方面:一是造山带古洋壳(蛇绿岩套)的地质地球化学;二是造山带及其两侧硅质岩形成的大地构造环境;三是造山带古地理学;四是造山带古海洋两侧盆地的形成序列;五是造山带古海洋及其矿产分布规律;六是编制各时期盆地原型分布图,进一步表述造山带古海洋与盆地的时—空结构特征。这不仅是进一步深化造山带研究的需要,而且在海相油气资源和沉积、层控矿产勘探中具有重要意义。
It was indicated that study of paleo-oceanology in orogenic belt would be a new domain according to the studying results of modern orogenic belt. There are 6 parts in the study of paleo-oceanology, i.e. （1） geological--geochemistry of paleo-oceanic crust （ophiolite suite）in orogenic belt; （2） the tectonic setting of the silicalites formed in orogenic belt and its both sides; （3） paleogeography in orogenic belt; （4） formative sequence of basins in the both sides of the paleo-ocean; （5）distribution of ore deposits and their relation to the paleo--ocean; and （6） mapping of basin prototypes for every tectonic stage. It is not only important to the study of orogenic belts, but also to exploration of marine petroleum re- sources, sedimentary mineral deposits and stratabound ore deposits.
