To study origin and morphologic assessment of Bayan lake, western Mongolia
Keywords:Bayan Lake, Fault, Khunguin khar,
Information about the origin of some lakes is out in previous studies on the genetics and morphology of lakes in Mongolia. One example of these is the genetics of Bayan nuur.
If we look at the morphology of the lake basin using a morpho-structure method based on previous studies, it is seen that it matches with the orthogonal fault of the Bayan lake basin.
Bayan lake originated by tectonic fault is a freshwater lake supplied with the deep water. In other words, thaw depression at the southwest coast of Bayan lake basin is related to the tectonic fault from northwest to the southeast (non-barrier).
It leads to a condition that water resource of the lake is supplied with the deep water which is contained in sediment for the Quaternary Glacial Period.
Cross section between main fault and crustal fault at the east coast of Bayan lake basin from northeast to the southwest presents the orthogonal compound fault.
If we look at overlaying depth of the lake with its area, volume, and isobath, it is seen that the origin of the lake is related to transfer of sands at the south side of the lake without a sand barrier.
Thus it confirms that Bayan lake originated in depression along tectonic fault.
