X-ray Diffraction on Unprepared Rock Samples: a Study of Sulphate Minerals
نویسندگان
چکیده
Introduction: Here we present an analysis of sulphate minerals from the Triassic coastline of the South West UK, utilising an Energy Dispersive X-Ray Diffraction (ED-XRD) instrument in a novel backreflection geometry that enables analysis of unprepared rock samples. Sulphate minerals are of particular interest in planetary science as they are a product of an aqueous altered environment. This study highlights the potential of a lightweight, compact instrument that could be deployed on the robotic arm of a Mars rover. Concept: Traditional angle-dispersive X-ray diffraction utilises the Bragg equation:

متن کاملThermal Analysis: A Complementary Method to Study the Shurijeh Clay Minerals
Clay minerals are considered the most important components of clastic reservoir rock evaluation studies. The Shurijeh gas reservoir Formation, represented by shaly sandstones of the Late Jurassic-Early Cretaceous age, is the main reservoir rock in the Eastern Kopet-Dagh sedimentary Basin, NE Iran. In this study, X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopic (S...
متن کاملشناسایی و نحوه تشکیل کانیهای رسی در خاکهای منطقه فرخشهر، استان چهار محال و بختیاری
Clay minerals have considerable effects on physico-chemical properties of soils. Using different techniques, mineralogy of silicate clays and their formation were investigated in selected soils from Chaharmahal and Bakhtiari Province. The study area is about 1300 ha and its soil moisture and temperature regimes are xeric and mesic, respectively. Geomorphologically, the area consists of differen...

متن کاملHigh-resolution X-ray diffraction with no sample preparation
It is shown that energy-dispersive X-ray diffraction (EDXRD) implemented in a back-reflection geometry is extremely insensitive to sample morphology and positioning even in a high-resolution configuration. This technique allows high-quality X-ray diffraction analysis of samples that have not been prepared and is therefore completely non-destructive. The experimental technique was implemented on...
