裂变径迹化石既是古地温的标志,又是年代的标志,因而可直接由它确定成烃期,从而为寻找工业油气藏指明方向。 裂变径这是含铀矿物自然核裂变中,核碎片穿过矿物晶格留下的幅射损伤的痕迹。这种痕迹,经酸蚀后在普通光学显微镜下可观测。 裂变径迹化石法是独特的岩石学方法,它使用简便,成效特殊,迄今尚未发现其它的方法能同时提供地温及时间的双重信息。
Fission track fossil is not only a sign of paleogeothermal, but also a symbol of the age, so it can be directly determined by the hydrocarbon generation period, so as to find the direction of industrial reservoirs. Fission path This is a trace of radiation damage left by nuclear fragments passing through the mineral lattice in the natural nuclear fission of uranium containing minerals. This trace, after acid etching in the ordinary optical microscope can be observed. Fission track fossil method is a unique petrology method, it is easy to use, with special effects, so far no other method has been found to provide both ground temperature and time information.
