The fluid inclusion composition of halite can help track chemical ancient fluids and, thus, serves as a reliable index to analyze brine in salt lakes. Qarhan Salt Lake (QSL) is the largest potash deposit China. Although mixing modern river water and Ca-Cl deep widely accepted potassium formation, characteristics time domain driving factors are still unclear. Here, inclusions primary samples col...

rise of groundwater levels in unconfined aquifers can cause dryland salinity to increase by several processes including; dissolution of windblown halite, and incorporation of saline clay pore water. The primary process of increased groundwater salinity is evaporation of shallow groundwater as it rises to within a few meters of the ground surface. in murray Basin, australia, the effect of drylan...

Time Resolved Raman Spectroscopy (TRRS) can provide subsurface information from multi-layered samples of transparent and translucent evaporative and silicate minerals up to several cm thick. Depth information was obtained using 3-ps pulsed laser excitation at 720 nm and a gated intensified CCD detector with stepwise increasing delay times. Blocks of different minerals were used as first, second...

This study is primarily focused on proving the potential of miniaturized Raman systems to detect any biomolecular and mineral signal in natural geobiological samples that are relevant for future application of the technique within astrobiologically aimed missions on Mars. A series of evaporites of varying composition and origin from two extremely dry deserts were studied, namely Atacama and Moj...

Abstract Quartz segregations in paragneisses from the Paleozoic basement of North Patagonian Andes contain highly saline multiphase fluid inclusions with rare daughter mineral ferropyrosmalite detected by Raman analysis, besides halite, sylvite, hematite, and/or magnetite. During heating experiments, L-V homogenization occurs (256–515 °C), followed halite dissolution (287–556 °C) and at 550–581...

The purpose of this study is to understand mineral diagenesis authigenic mineral and the effect of climate on mineral of Pleistocene-Holocene sediment deposits in the Southern Kenya Rift. Lake Magadi unique geologic settings are characterized by extreme alkalinity and high silica activities. The mineralogical analysis was achieved by X-Ray diffraction (XRD) and Scanning Electron Microscopy (SEM...
