摘　　要：巴彦浩特盆地石炭系磷灰石裂变径迹年龄研究分析认为,该盆地磷灰石裂变径迹退火年龄自侏罗纪以后,侏罗系再未经历高于120℃的温度,而石炭系在白垩纪末普遍达到磷灰石的最大退火温度。结合盆地地质情况,石炭系在地质历史上经历的古地温不会太高,一般没有超过120℃,所经历的最高地温时间是晚白垩世,大量有机质在这一时期进行生排烃,具有晚期成烃的特点。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 paleo -geotemperature that Carboniferous went through at geologic history could not be too high and commonly was under120℃.The highest geotemperature occurred at late Cretaceous when large amount of organic materials began to generate hydrocarbons.It has the characteristics of late hydrocarbon generation.
