Bayanhaote Basin

The Bayanhaote Basin (), also known as Bayanhot Basin, is a geographic region located in the west-central part of Inner Mongolia Autonomous Region. It is a superimposed basin that 
underwent a long-term sedimentary evolution process from transgression to retrogression during the Carboniferous to Late Permian.
The Bayanhot Basin is a composite and superimposed basin developed in the crossing zone of the Qinlin-Qilian-Helan trifurcate rift system (秦、祁、贺三叉裂谷系) during the beginning of Early Palaeozoic Era (早古生代早期) of crossover zone.
It has been a self-flowing tectonic basin since the Mesozoic. In the early 1950s, oil and gas exploration in this area began.
