The genesis and significance of pyrite in the Ordovician Majiagou Formation in the central and eastern Ordos Basin

Petroleum Geoscience
The geochemical data of the gas sourced from the Majiagou Formation indicate low organic content and high thermal maturity, which make the evaluation of the hydrocarbon generative potential difficult. However, the low organic abundance and high thermal maturity of the Majiagou Formation make it difficult to evaluate its hydrocarbon ...

The lithology and reservoir properties of the Lower Ordovician Majiagou formation at the Tabamiao gas field (Ordos Basin, China)

Moscow University Geology Bulletin, 2016
The Ordos Basin is known for rich natural gas, coal, and oil fields; it is an important mineral raw material and electric power base of China. Among the recently discovered gas fields within the Yimeng Monocline, the Sulige and Tabamiao gas fields, where gas reserves are found in Lower Ordovician carbonate rocks, are best known. We have identified five

Paleoenvironment of the Fifth Member of the Ordovician Majiagou Formation, Central Ordos Basin: Evidences From Trace Elements and C–O Isotopes

Geological Journal
ABSTRACTCarbonate rocks hold significant importance in investigating depositional environments. This paper reconstructs the paleoenvironment of carbonate rocks of the Majiagou Formation in the Ordos Basin through the analysis of trace elements and carbon–oxygen isotopes.
