Alteration characteristics of sandstone-type uranium mineralization in Bayantala basin,Inner Mongolian Autonomous region;

In the Bayanhaote Basin,there is a linear correlation between the depths of the enclosure samples in different ages and the homogenization temperatures of enclosure, especially those in middle and later periods, and there can be divided in vertical direction into four stages which are immature stage,low mature stage, mature stage and high mature stage.

According to exploring result in the Bayanhaote Basin,the petroleum system is analyzed, and two petroleum systems are distinguished,those are Hercynian Indosinian de.

Carboniferous Reservoir Features and Diagenesis,Bayanhot Basin;

The structural evolution of Bayanhot Basin underwent a structural transform from compressional deformation to extensional deformation.

Analysis on uranium metallogenic conditions and prospecting prospects in Zhunbayingtala basin;

Based on age study of apatite fission track of Carbonif-erous in Bayanhaote basin,it is believed that the annealing age was after Jurassic and Jurassic had not experienced tem-peratures over120℃ever since then while Carboniferous largely reached the highest annealing temperature of apatite at the end of Cretaceous.

The surface of Bayanhaote basin is covered largely by desert and gobi.
