Thermodynamic and Kinetic Studies of Dolomite Formation: A Review
Minerals, 2023 The “dolomite problem”, which has confused scientists for nearly two centuries, is an important fundamental geological problem. The mineralogical characteristics of carbonate minerals show that the dolomite structure consists of an ordered arrangement of

The Dolomite Problem: A Matter of Time
ACS Earth and Space Chemistry, 2022 : Why is the mineral dolomite, CaMg(CO 3 ) 2 , abundant in ancient sedimentary rocks but scarce in modern rock-forming environments? What are the natural processes that lead to the characteristic Mg − Ca order in the dolomite structure?
