  Solubility Product Constants for Natural Dolomite (0–200 °C) Through a Groundwater-Based Approach Using the USGS Produced Water Database
  Hamish A. RobertsonHilary CorlettCathy HollisFiona F. Whitaker

  The calculation of a reliable temperature dependent dolomite solubility product constant (Ksp−dol) has been the subject of much research over the last 70 years. This study evaluates log10(aCa2+/aMg2+) values using...

  Black Shale Deposition and Early Diagenetic Dolomite Cementation During Oceanic Anoxic Event 1: The mid-Cretaceous Maracaibo Platform, Northwestern South America
  Daniel A. PetrashNur GueneliJochen J. BrocksJosé A. Méndez-DotGabriela González-ArismendiSimon W. PoultonKurt O. Konhauser

  Thin laterally continuous organic-rich dolomitic marlstones were deposited in the extended Late Aptian - Early Albian epicontinental sea of northwestern South America. These intervals are the proximal equivalents of thick...

  Isotope Hydrology of Early Paleogene Lake Flagstaff, Central Utah: Implications for Cordilleran Evolution
  Justin H. VanDeVeldeGabriel J. Bowen

  Lacustrine sediments from Paleogene foreland basins of the North American Cordillera serve as powerful integrators of information on climatic and tectonic conditions, but episodes of hydrologic connection between basins may...

  Self-accelerating Dolomite-For-Calcite Replacement: Self-organized Dynamics of Burial Dolomitization and Associated Mineralization
  Enriquel MerinoÀngels Canals

  A new dynamic model of dolomitization predicts a multitude of textural, paragenetic, geochemical and other properties of burial dolomites. The model is based on two postulates, (1) that the dolomitizing...

  Hydrothermal Dolomite in the Timiskaming Outlier, Central Canadian Shield: Proxy for Late Ordovician Tectonic Activity
  G. R. DixS. SharmaI. S. Al-AasmM. ConiglioR. LinnenJ. F. V. RivaA. Achab

  The Timiskaming Paleozoic outlier on the central Canadian Shield preserves a thin distal portion of the once extensive Taconic deep-water shale succession that extended across eastern Laurentia. Within this succession,...

  The Role of Biomineralization in the Origin of Sepiolite and Dolomite
  Santiago LegueyDavid Ruiz De LeónAna Isabel RuizJaime Cuevas

  Sepiolite is an important industrial mineral whose mechanism of formation and detailed origin are still not clear. Sepiolite is frequently found with dolomite, Mg-smectites or palygorskite in the Intermediate Unit...
