摘    要:介绍了应用磷灰石裂变径迹(AFTA)方法研究沉积盆地古地温的原理及研究现状,并以东营凹陷的具体数据为例进行了热史反演。研究表明东营凹陷的古地温梯度基本呈降低的趋势以及“马鞍形”的演变特点。从而表明磷灰石裂变径迹研究沉积盆地古地温是一种行之有效的方法,能够为古地温场的研究提供可靠的依据。

关 键 词:磷灰石裂变径迹 古地温 东营凹陷 沉积盆地

Abstract:This article introduces the theory and present situation of apatite fission track analysis (AFTA) means in syudying the paleo geotemperature of sedimentary basin, and concrete data in Dongying depression is applied to invert the paleo geotemperature. It can be seen that the paleo geotemperature gradient in Dongying depression has a descendant trend and an U shaped evolvement characteristic. It can be seen that the apatite fission track analysis (AFTA) means is an effective way in researching paleo geotemperature of sedimentary basin. This means can supply reliable basis for the study of paleo geotemperature field.
Keywords:apatite fission track analysis  paleo geotemperature  study basis  Dongying depression
