  annealing age
     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.
     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。

The combinative analysis method of thermal history inversion with apatite fission tracks has been discussed in the paper.It cornbnes two modelling techniques,the Monte Carlo method and Simplex method.The Monte Carlo Box used to generate random numerical data gives initial values for geothermal inversion.The Simplex method is for searching appropriate geothermal temperature.The combination of the two methods can avoid tripping in a local minimal position for the object function and give a suitable solution of thermal history.The utlizable and stable text has been taken by the inversion calculation of a theoretical model. Even the difference between the initial and theoretical values is 20-50℃,the suitable results of the inversion can be got.The example of thermal history inversion has been calculated with apatite fission track data.The sample came from an oil well of Eastern China. The result of thermal history inversion gives a clear reflection of structural and sedimental development.

讨论了利用磷灰石裂变径迹资料反演热演化史的综合分析法.这一方法综合了Simplex和MonteCarlo方法的特点.初值选择采用MonteCarloBox选择法,而反演迭代则应用Simplex方法.由于应用了MonteCarloBox,从而保证了初值在某一限定区域内的随机性选择,避免了目标函数陷入局部极值区而使反演失真的情况.在地质条件约束下,它可以成功地获得目标函数极小值或极小值邻域内的极值以及它们对应的热史的解.应用理论模型,验证了本方法的有效性和稳定性.在初值偏离真值较远(20-50℃偏差)的情况下,本方法也可以获得满意的解.以中国东部某凹陷井中实测磷灰石裂变径迹长度分布和退火年龄资料为实例,进行了热史的反演计算模拟,结果清楚地解释了样品所处地区的构造和沉降史.

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.

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。
