本文应用诱发裂变碎片径迹等方法,以中国南方震旦-寒武系中一些碳(碳酸盐)、硅、泥岩为例,研究铀在沉积一成岩及后生过程中的分布特征。岩石光薄片曾于反应堆垂直孔道内照射。中子积分通量为2.03×10~(10)n/cm。
In this paper, some carbon (carbonate), silicon and mudstone in the Sinian-Cambrian system in southern China are used as examples to study the distribution characteristics of uranium in sedimentary-diagenesis and epigenetic processes. Rock chip was irradiated in the vertical hole of the reactor. The neutron flux is 2.03 × 10 ~ (10) n / cm.
