The mineral dolomite and the uncertainties surrounding its origin have attracted the attention of earth scientists for over a century. The core of the dolomite ‘‘problem’’ is the apparent paradox posed by the paucity of dolomite in modern marine depositional environments versus its relative abundance in the sedimentary rock record. Solving this problem requires knowledge of the conditions under which the mineral forms and the rate of precipitation under those conditions. As a working hypothesis… 

Sedimentary dolomite: a reality check

Abstract The failure to precipitate dolomite experimentally at low temperatures or from seawater in which it is both supersaturated and the most thermodynamically favoured carbonate phase, together

Breakdown of the Ostwald Step Rule--The Precipitation of Calcite and Dolomite from Seawater at 25 and 40 o C

The scarcity of recent dolomite contrasts strongly with its common abundance in ancient sedimentary rocks, leading to the paradox commonly referred to as the "dolomite problem". Despite many

A New Model for Formation of Lacustrine Primary Dolomite by Subaqueous Hydrothermal Venting

Almost 230 years after it was first described, formation of the mineral dolomite remains enigmatic. Dolomitic rocks are abundant throughout the geological record, and most are thought to form by

Surface chemistry allows for abiotic precipitation of dolomite at low temperature

TLDR
Results indicate that natural surfaces, including organic matter and microbial biomass, possessing a high density of carboxyl groups may be a mechanism by which ordered dolomite nuclei form, and suggest that sharp biogeochemical interfaces that promote microbial death, as well as those with high salinity may, in part, control car boxyl-group density on organic carbon surfaces.

Abstract Despite intensive research over more than 200 years, the origin of dolomite, the mineral and the rock, remains subject to considerable controversy. This is partly because some of the

We document stoichiometric dolomite occurring in a nonsaline Quaternary soil on the Kohala peninsula, northwestern Hawaii. Geologic constraints and geochemical and isotopic data confirm that this

Transport-controlled hydrothermal replacement of calcite by Mg-carbonates

Dolomitization is one of the most important diagenetic processes, but the reaction rate and time scale of dolomitization remain a topic of controversy. We conducted experiments in which the reaction
