摘要
The Jurassic Longshan Formation outcropping in the Agelendaba groove in the western Kunlun Mountains of Gela in Xinjiang is rich in sedimentary structures and clear sedimentary sequences. The research on the petrology and sedimentology characteristics shows that there are the mixed tidal flat deposition products in Longshan Formation. The analysis of the paralic environment detrital minerals provenance reveals that the sediments comes from the orogenic belts of the recyclings and the study of the regional tectonic background show that this area began the process of conversion from sea to land in the Early-Middle Jurassic.
