Origin and reservoir characteristics of Ordovician dolostones in the Ordos Basin

open access: yesNatural Gas Industry B, 2017
Dolomite is one of the most important rock types for the development of the Ordovician effective reservoirs in the Ordos Basin. Its genesis remains controversial due to its complex and variable rock texture and occurrence. In this paper, through analysis

Multiple proxies demonstrate the mechanism of dolomitization variations during global warming periods

open access: yesGeosystems and Geoenvironment, 2023
The genesis of the sedimentary dolomite has been an unexplained mystery for more than two centuries, known as the 'dolomite problem'. There may be some coupling relationship between the Phanerozoic variations in dolomite abundance and major geological ...
