Introduction: By analyzing the stable Cl-isotopes of halite from the Zag H-breccia and comparing the results with those from other chondritic materials we can provide new information about isotopes in the early Solar System. In particular Cl-isotope work may complement O-isotope studies. We show for the first time that substantial Cl/Cl fractionation exists between chondrite components. Zag hal...

Fluid inclusions in evaporite minerals (halite, gypsum, etc.) potentially preserve genetic records of microbial diversity and changing environmental conditions of Earth's hydrosphere for nearly one billion years. Here we describe a robust protocol for surface sterilization and retrieval of DNA from fluid inclusions in halite that, unlike previously published methods, guarantees removal of poten...

The Salar de Uyuni, a salt pan located in the Bolivian Andes, was subject to hydrogeological and hydrochemical investigations between June and September 2009. During a drilling and sampling campaign halite cores were gained from different bore holes with depths between 2 and 12 m at two locations in the north eastern and the central part of the Salar (named SLT-01 and SLT-03, respectively). Bri...

LÕanalyse de la texture du sel gemme naturel et du halite dŽformŽ expŽrimentalement a montrŽ quÕil se produit une orientation prŽfŽrentiel le du rŽseau dans les cristaux de halite. Les paramtres dՎlasticitŽ pour une sŽrie dÕagrŽgats polycristallins de halite sont calculŽs en utilisant les fonctions de distribution dÕorientation. Ils sont alors utilisŽs pour Žlaborer des modles sismiques dans...

In this study porous alumina samples were prepared and then coated using the biomimetic coating technique using a five times Simulated Body Fluid (5.0SBF) as the growth solution. A coating was achieved after pre-treatment with concentrated acid. From elemental analysis, the coating contained calcium and phosphorous, but also sodium and chlorine. Halite was identified by XRD, a sodium chloride p...

Solubilities of corundum (Al2O3) and wollastonite (CaSiO3) were measured in H2O–NaCl solutions at 800 C and 10 kbar and NaCl concentrations up to halite saturation by weight-loss methods. Additional data on quartz solubility at a single NaCl concentration were obtained as a supplement to previous work. Single crystals of synthetic corundum, natural wollastonite or natural quartz were equilibrat...

The mineral composition of the microbial mats at La Banya spit was studied. The spit is formed by a narrow sand bar and a peninsula and is located south of the main body of the Ebro Delta (Tarragona, Spain). Although quartz was the predominant mineral component in all sampling sites, clay, feldspars, calcite, aragonite, halite, dolomite and gypsum were also found. An increase in both the fine m...
