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。

Abstract

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 resources,sedimentary mineral deposits and stratabound ore deposits.
