الملخص EN

The Tih Plateau Cuesta has been formed in an area of slightly northerly tilted sedimentary layers with different degrees of solidity, dated back to the Cretaceous Age.

A group of subterranean factors have raised its escarpment, then some surface factors such as water erosion have affected its formation during the Pluvial period of the Pleistocene.

As a result, it has parallelly retreated to the north about 8km.

The Cuesta stretches to 78km, overlooking a wide deebretion that is parallel to its axis on about 400m high, while the width of its façade differs from a place into another, but its slope is steep.

A row of downfolds, separated by rock uplifts, characterize the façade that is 151.1km², forming 23.4% of the area under investigation.

Sewage effluents, which could not break through its escarpment, have left gullies on its façade.

The accompanying deebretion gradually steeps northwesterly towards the axis of the Cuesta that has ruins of hills and is westerly open to the plain of the bottom.
