The study of Ordovician carbonate rock from Tahe Oil Field indicates that some of calcite cements related with meteoric diagenetic environment show bright-and-weak luminescence zones and the concentration of Sr, Na, Mn and Fe elements has a good corresponding relationship with luminescence zones. That is, bright luminescence zone has high concentration of Mn and Fe and low concentration of Sr and Na while weak luminescence zone has high concentration of Sr and Na and low concentration of Mn and Fe, which implies the effect of meteoric fresh water to calcite cementation. The luminescence zones are controlled by different element textures and they reveal the change of element concentration within diagenetic fluid and the crystallization rate of calcite. It is suggested that this instance is related, in some extent, with the open fluid condition in meteoric diagenetic environment. In general, the late-stage zones of calcite cement show relative bright luminescence with relative high concentration of Mn and relative low concentration of Sr and Na, which reveals the increasing meteoric diagenesis during palaeokarst process related with Caledonian-Hercynian tectonic movement.
