Special Publication 28 has its roots in the 22nd Annual Research Symposium of SEPM entitled Concepts and Models of Dolomitization – Their Intricacies and Significance held on April 3,1979 in Houston, Texas as part of the joint annual meetings of AAPG and SEPM. The purpose of that symposium was to express the state-of-the-art of the study of the elusive process(es) of dolomitization. Most of the contributions in this volume are concerned with apparent early, nearsurface dolomitization, either by hypersaline brines, by the marine-meteoric mixing model or some variant thereof, or by both mechanisms where more than one phase or kind of dolomite exists, or where the origin of a particular dolomite is uncertain. Other models and aspects of dolomitization are treated here as well.read more

Dolomite: occurrence, evolution and economically important associations
TL;DR: Dolomite is not a simple mineral; it can form as a primary precipitate, a diagenetic replacement, or as a hydrothermal/metamorphic phase, all that it requires is permeability, a mechanism that facilitates fluid flow, and a sufficient supply of magnesium.

Concepts and models of dolomitization: a critical reappraisal
TL;DR: A review of the state of the art in dolomite research can be found in this article, where the authors highlight the major advances and controversies of the last 20-25 years.
Journal ArticleDOI
Climatic and oceanographic isotopic signals from the carbonate rock record and their preservation
TL;DR: In this paper, the effects of post-depositional diagenetic alteration of marine limestones are identified using a combination of their mineralogical potential and depositional setting, together with subsequent changes in relative sea-level and burial history.

Microbial mediation as a possible mechanism for natural dolomite formation at low temperatures

TL;DR: In this paper, the direct mediation of these anaerobes can overcome the kinetic barrier to dolomite nucleation, and that they may play an active role in the formation of this mineral in natural environments.

Constraints on the Formation of Sedimentary Dolomite
Paul A. Baker,Miriam Kastner +1 more
TL;DR: The experimental replacement of calcite and aragonite by dolomite under a variety of conditions indicates that dolmitization can take place in marine and lacustrine environments under two conditions: low dissolved sulfate concentrations and insubstantial contemporary silica diagenesis.
