ON STUDY OF PALEO-OCEANOLOGY IN OROGENIC BELTS

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.
