| 摘 要： | 干酪根自由基浓度是研究有机质热演化的有效指标之一.也是研究沉积盆地古地温的热参数之一.本文根据新生代盆地干酪根自由基浓度与样品埋藏深度的关系,建立了推算古地温梯度的标准曲线图,并利用此标准曲线估算了塔里木盆地和辽河盆地两口井的古地温梯度.这一方法对于无镜质体地区和无磷灰石地区的古地温研究提供了新的思路.

| Abstract: | The free radical concentration (Ng) of kerogen is a valid index to study thermal maturation of organic matter and paleotemperature of sedimentary basin. A standard curve map was established to estimate paleothermal gradients based on the relationship between Ng and buried depth of kerogen samples from the Cenozoic basin. The paleo-geothermal gradients of well MC1, the Tarim basin and well LR16, the Liaohe basin were estimated by using the stardard curve. It gived a new way to study paleo-temperature in an area where vitrinite grain can not be found and apatite fission track analysis can not work because of lack of a patlte. |
