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。

Abstract:

This article introduces the theory and present situation of apatite-fission-track-analysis (AFTA) means in studying 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.

Key words: apatite fission track analysis, paleo-geotemper-ature, study basis, Dongying depression
