CURRENT ASPECTS OF BASIN-MOUNTAIN TRANSFORMATION AND BASIN ANALYSIS

Much research of continental dynamics has focused in recent years on the relationship between the basin system and orogenic system which are interpreted as two basic and essential tectonic units and twins in the temporal and spatial evolution of.the crust.
The sedimentary basin system is a whole organic system of accumulation spaces and provenances.A basin is the product of the crustal movements in response to geodynamics. The formation and development of the basins,in turn,are closely bound up with those of the orogenic zones.The basin analysis including basin nature,type,evolution and dynamics of basin nature transformation is conduced on the basis of the features of volcanic rocks, and strikes of ophiolites and melanges,and/or island-arc zones.Furthermore,the interrelations among the sedimentary bodies of distinct provenances may feedback the information about the geodynamics and basin-mountain transformation.The structural elements of the basin boundaries,growth sequences of the filling deposits from different source areas,and geometry and stacking patterns of the deposits have the same important implications as the ophiolites as well.
The orogenic zones record the crustal tectonism and dynamic transformation,and represent intercontinental movements,extinct oceans and landmasses,and epicontinental basins.In other words,the orogenic zones were originated from the basin systems,and represent the extinct oceanic systems and basin systems,In this paper,the authors have proposed the new knowledge of "basin-mountain transformation",and offered some thoughts on "plate tectonics controlling basins,basins transforming into mountains,and mountains controlling basins".
