Reactive-transport models are developed here that produce dolomite via two scenarios primary dolomite no caco3 dissolution involved versus secondary dolomite dolomitization, involving caco3 dissolution.Using the available dolomite precipitation rate kinetics, calculations suggest that tens of meters of thick dolomite deposits cannot form at near room temperature 25-35c by inorganic.

  • Abiotically Formed Primary Dolomite In The Mid

    This study discusses the role of smectitic clays in the formation of an abiotic physio-chemical primary dolomite within an evaporative alkaline-saline marginal lake system, in the absence of carbonate precursor and microbes.The present work has been achieved in terms of textural, mineralogical, and geochemical characteristics of dolostones in the mid-eocene bartonian lacustrine succession.

  • High P H And Primary Dolomite A Reply

    Wells1962 pointed out that dolomite and gypsum around qatar peninsula were derived from sea water which was left behiiic in the sediment on the upper part of the tidal aatsj 011 concentration by evaporation during the time between the spring or storm high tides.1-ie was not sure, however, as to what extent the dolomite was primary and what.

  • Dolomite Overgrowths Suggest A Primary Origin Of

    Trace dolomite within the sample supports the primary cone-in-cone hypothesis.The host sediment is a biosiliceous mudstone containing abundant rhombohedral dolomite grains.Dolomite rhombohedra are also distributed throughout the calcite of the cone-in-cone.

  • Formation Of Dolomite In Recent Island Arc

    Primary dolomite is directly precipitated from so-lution either as sediment or cement, whereas secondary dolomite is formed via replacement of precursor caco3 in the presence of mg21-bearing u-ids.Primary dolomite is comparatively rare, forming in saline lakes and.

  • Abiotically Formed Primary Dolomite In The Mid

    Therefore, dolomite formation needs now to connect with the presence of smectite minerals in the precipitation medium.As revealed from petrographic characters of dolomite with its associated smectite fig.4ah, the studied dolomite has been interpreted as a primary precipitate enclosing the previously-precipitated smectitic clay minerals.
