Mehrabad bentonite deposit appears to be derived from the volcano- sedimentary materials of Oligo-Miocene age by transformation in a lagoon environment. Based on analysis, bentonite samples contain minerals such as montmorillonite, albite, clinoptilolite, quartz, cristobalite, calcite, gypsum, halite, muscovite and nantronite. Conversion of shard glasses to bentonite and zeolite has occurred un...

Abstract The origin, evolution, and interplay of brine hydrocarbon fluid systems play a crucial role in the formation deep sediment-hosted base metal ore deposits. Here we investigate ratios halogens, noble gases, stable C S isotopes, budgets aqueous brines, which deposited deep-seated near-surface hydrothermal Zn-Pb mineralization hosted by Zechstein carbonates Lower Saxony Basin (North German...

Introduction: Chondrites reveal signs of aqueous alteration on their parent bodies [1-4] that occurred under a broad range of pH. The dominance of secondary Mg-phyllosilicates (saponite, serpentine, chlorite) in pervasively altered CI and CM chondrites [1-4] suggests alkaline conditions during deposition [5,6]. However, localized occurrences of phosphates and carbonates in CM carbonaceous chond...

The concept of the mineral classification in the Mineral Powder Diffraction File (MPDF) is somewhat different from that used in classical mineralogical references. The goal of the classification is to exploit the crystal chemistry characteristics to the fullest to assist in the identification of mineral phases. The primary criterion is the similarity of the diffraction pattern, which results fr...

Researchers seek to identify dry lake bed deposits on Mars, if present. Primary tools in this search include the 1996 Mars Global Surveyor Thermal Emission Spectrometer (TES) and the 2001 Mars Odyssey multi-channel radiometer THEMIS. Interpretations are based on a comparison of the recorded signatures to laboratory spectra. Texture affects both the shape and contrast of the spectral signatures ...

-Inorganic chemical analyses and short-chain aliphatic acid content are used to interpret the origin and compositional evolution of formation waters in the Alberta portion of the Western Canada Sedimentary Basin. Forty-three formation water samples were obtained covering a stratigraphic interval from Devonian to Cretaceous. The data show that: (1) there is a subaerially evaporated brine compone...

With a mean precipitation rate, much lower than that of the world, Iran is among the countries that face severe water challenges. The present study has dealt with the evaluation of hydrochemistry of Faryab spring water in Hormozgan Province, Iran. Four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, pH, and s...

This work aims to investigate the hydrochemical characteristics and formation mechanisms of shallow groundwater in a part Nanchang section Ganfu plain. The data from 90 samples were interpreted by methods mathematical statistics, Piper diagrams, Gibbs plots, ratio graphs ions, geochemical modeling. results show that is weakly acidic, average concentration cation decrease Ca2+ > Na+ Mg2+ K+, ...
