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 ...
