Rowland, D. and May, P.M. (2013)AThis is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Abstract A comprehensive characterization of densities / apparent molar volumes for the aqueous solutions of magnesium chloride, calcium chloride and potassium iodide to high temperatures and pressures has been performed based on the Pitzer equations. The unusual availability of overlapping high quality independent sets of experimentally measured data for these systems allows the relevant thermodynamic quantities to be calculated with a high degree of confidence over wide ranges of conditions (< 8 mol/kg; 273-573 K; 0.1-100 MPa). A realistic assessment of experimental uncertainty indicates that an adequate description of volumetric behaviour is achieved by the standard Pitzer model without extensions. The experimental accuracy implied by differences between independent observers, however, is more than one order of magnitude worse than typically-claimed estimates of experimental precision.

“…The application BULK allowed to calculate bulk fluid properties (e.g. density) of individual FIs using the equation of state for aqueous systems of Krumgalz et al (1996) and the volume fractions of the liquid phase of FIs at room temperature. The program LONER32 was used to calculate the isochore slope for FIs from the different phases according to the model of Bodnar and Vityk (1994).…”

Bois-Préau, 92852 Rueil-Malmaison Cedex -France e-mail: aleianna@unina.it -marta.gasparrini@ifpen.fr -tatyana.gabellone@unina.it -smazzoli@unina.it Résumé -Dolomitisation tardo-diagénétique dans les calcaires de bassins triassiques de l'Apennin Méridional (Italie) -Les carbonates pélagiques triassiques de l'Unité de Lagonegro, dans l'Apennin méridional hébergent des corps dolomitiques discordants. Ces dolomies montrent les structures typiques connues comme "zébra" ou dolomite "à selle". Dans cette note, on présente les résultats d'observations de terrains et pétrographiques et les données géochimiques obtenues sur trois affleurements. Les données de terrain indiquent que les structures de type "zébra" et bréchifiées sont contrôlées par la stratification très régulière des calcaires micritiques. La dolomitisation a comporté le remplacement du calcaire et de la précipitation de dolomite cristalline dans les vides sous un champ de contraintes extensionnelles. Les températures d'homogénéisation sont comprises entre 80 et 120 °C, avec un mode à (95 ± 10) °C. Après une correction de pression, elles indiquent une température maximale de formation de la dolomie d'environ 110-115 °C. Les températures de fusion de la glace indiquent une salinité comprise entre 2 et 6 wt% NaCl eq, avec une moyenne de 4.2 %. Les valeurs de δ 13 C sont comparables à celles de l'eau de mer triassique, tandis que les valeurs de δ 18 O sont fortement appauvries. Les valeurs du rapport 87 Sr/ 86 Sr sont au contraire plus élevées que celles estimées pour l'eau de mer triassique, mais comparables à celles du Miocène Moyen-Supérieur. Ces résultats indiquent une dolomitisation accomplie par des fluides relativement chauds avec une salinité voisine de celle de la mer et une composition isotopique comprise entre celle de l'eau de mer et celle de saumures de bassin. On propose que cette dolomitisation a été achevée par les eaux expulsées par les formations qui entourent les carbonates pélagiques triassiques ou celles du mélange sous-jacent. L'intégration des données sur l'histoire thermique et de la déformation indique, si l'on assume un équilibre thermique avec les roches encaissantes, que ce phénomène ait eu lieu après le pic d'enfouissement pendant les premiers stades de l'exhumation. Enfin, puisque les dolomies sont assez répandues dans la région, il est bien possible qu'une importante circulation de fluides ait intéressé l'entier fold-and thrust-belt pendant la déformation, y compris les unités de la Plate-forme Apulienne, qui héberge des importants réservoirs d'hydrocarbures.

“…When data was unavailable in Ref. 4, data of Krumgalz et al 5 valid at 25 C were used, with pure water density data at the temperature of interest. In their model, Krumgalz et al 4 used the somewhat obsolete pure water density calculations of Kell 6 because those data or very similar values were used in most experimental determinations of electrolyte solution densities.…”

The alkaline earth carbonates are an important class of minerals. This volume compiles and critically evaluates solubility data of the alkaline earth carbonates in water and in simple aqueous electrolyte solutions. Part 1, the present paper, outlines the procedure adopted in this volume in detail, and presents the beryllium and magnesium carbonates. For the minerals magnesite (MgCO 3 ), nesquehonite (MgCO 3 Á3H 2 O), and lansfordite (MgCO 3 Á5H 2 O), a critical evaluation is presented based on curve fits to empirical and=or thermodynamic models. Useful side products of the compilation and evaluation of the data outlined in the introduction are new relationships for the Henry constant of CO 2 with Sechenov parameters, and for various equilibria in the aqueous phase including the dissociation constants of CO 2 (aq) and the stability constant of the ion pair MCO 0 3 ðaqÞ (M ¼ alkaline earth metal). Thermodynamic data of the alkaline earth carbonates consistent with two thermodynamic model variants are proposed. The model variant that describes the Mg 2þ ÀHCO À 3 ion interaction with Pitzer parameters was more consistent with the solubility data and with other thermodynamic data than the model variant that described the interaction with a stability constant.
