Reasons for the natural formation of Lop Nur landform

According to the change of the lake, some explorers think that Lop Nur is a "wandering lake" or "alternating lake", which swings between 39 ~ 40 and 40 ~ 41north latitude. Recently, Chinese scientists have found that there are obvious river deltas in the northwest and southwest corners of the lake, indicating that when the water systems in the lower reaches of Tarim River and Peacock River changed, rivers once flowed into the lake basin from different directions. Lake basin is the lowest place in Tarim basin, with less sediment entering the lake and weak sedimentation. Dating and sporopollen analysis of lake bottom sediments prove that Lop Nur has long been the catchment center of Tarim Basin. It's just that the lake sometimes goes north and sometimes south, which is not a large-scale "wandering".
