STEM investigation of exsolution lamellae and "c" reflections in Ca-rich dolomite from the Platteville Formation, western Wisconsin
Zhizhang Shen, Hiromi Konishi, Philip E Brown +1
Dolomite crystals in partially dolomitized limestone from the Platteville Formation are both compositionally and microstructurally heterogeneous. A single dolomite crystal usually…
Z-contrast imaging and ab initio study on "d" superstructure in sedimentary dolomite
Zhizhang Shen, Hiromi Konishi, Izabela Szlufarska +2
Nano-precipitates with tripled periodicity along the c-axis are observed in a Ca-rich dolomite sample from Proterozoic carbonate rocks with "molar tooth" structure. This observatio…
Investigation of the role of polysaccharide in the dolomite growth at low temperature by using atomistic simulations
Zhizhang Shen, Philip E. Brown, Izabela Szlufarska +1
Dehydration of water from surface Mg2+ is most likely the rate-limiting step in the dolomite growth at low temperature. Here, we investigate the role of polysaccharide in this step…
Modeling the Effect of Dissolved Hydrogen Sulfide on Mg2+-water Complex on Dolomite {104} Surfaces
Zhizhang Shen, Yun Liu, Philip E. Brown +2
The key kinetic barrier to dolomite formation is related to the surface Mg2+-H2O complex, which hinders binding of surface Mg2+ ions to the CO3 2- ions in solution. It has been pro…
