Abstract

The Fifth Member of the Ordovician Majiagou Formation in Xingxian and Liulin, Shanxi Province consists of carbonates and evaporates that deposited in low-energy, restricted, saline environments of an epicontinental-sea. After deposition, these carbonates and evaporites underwent a long-period of exposure and karstification until Carboniferous regional submerging occurred.

Twenty six elements were analyzed with the Majiagou carbonate rock samples. The data from 176 samples collected firm the two locations indicate 1) the sedimentation has largely controlled the CaO/MgO and the highier contents of Ba, Na2O, and B; 2) the paleokarstification has resulted in a concentration of Al2O3, Fe2O3, P, V, Ti, and La and output of Ba and Sr; and 3) the sedmentation and burial diagenesis has governed the Fe2+ and Mn2+ distribution.
