Abstract

Abstract

Different orogenic belts are composed of different tectonic facies units. The division of tectonic facies reveals the basin skeleton and the evolution rules of an orogenic belt. In 1∶250 000 geological mapping of the Donggi Conag Hu area in the East Kunlun orogenic belt, considering the timing evolution and tectonic setting as the main clues, and according to the tectono-paleogeography, basin type and matter construction type in different evolution stages, we divide the tectonic facies into seven big facies including 21 small facies, such as extensional oceanic ridge facies, offset (extensional) trough facies, carbonate seamount facies, carbonate platform facies, abyssal plain facies, continental sliver facies, foreland basin facies, molasses basin facies and so on. From this research we have produced a 1∶250 000 tectonic facies diagram of the Donggi Conag Hu area, and diagrams which display the orogenic processes and tectonic facies evolution. The application of tectonic facies in geological mapping deepens the study of the spatial relation of strata units and basin filling sequences during orogenic mapping, and we reveal the forming, substance composition and evolution processes of orogenic belts in the east part of the East Kunlun orogenic belt in detail.
