| چکیده | ||
| Introduction: The Zeytoon kaolin deposit is located in 40Km northwestern Abadeh city, and represents one of the most important refractory clay deposits in the Abadeh district (Shakeri, 2014). This deposit formed synchronous with the global clay mineralization event at the Permian–Triassic boundary and is of considerable geological and economic significance (Shakeri, 2014). Its kaolinite and illite-rich composition makes it suitable for use in refractory materials, ceramics, glazes, and other industrial applications (Murray, 1988; Dill, 2016). The present study aims to investigate the mineralogical and geochemical characteristics of the deposit and to constrain its origin and genetic evolution using major elements, trace elements, and rare earth elements. Method In this study, systematic sampling was carried out from the surface to a depth of approximately 20 m, guided by macroscopic characteristics (texture and color) and following the methodologies outlined by Rose et al. (1979). Following sample preparation and pulverization, 10 samples were submitted to the Geological Survey of Northwestern Iran and the ZarAzma Laboratory in Tehran for XRD and XRF analyses to determine mineralogical composition and major-element concentrations, respectively. Additionally, 11 samples were sent to Chemex Laboratories in Toronto, Canada, for ICP MS analysis to quantify rare and rare earth element (REE) contents within the deposit. | ||
