a total of 148 groundwater samples were collected from bore wells from thirumanimuttar sub-basin for two seasons to identify major geochemical process activated to alter groundwater chemistry. the study revealed relationships with the lithology and anthropogenic process. groundwater in the region was dominated by na – ca – mg and cl and hco3 types. the (ca +mg) versus tz+ plot for both seas...
Feldspars are ubiquitous natural dosimeters widely used in luminescence dating. Despite decades of research, the lattice defects as well mechanisms involved production feldspars remain poorly understood. The recently developed method infrared photoluminescence (IRPL) excitation-emission spectroscopy has revealed presence two electron trapping centres emitting IRPL at 1.3 eV and 1.41 (IRPL1.3 IR...
Introduction: The detection of minerals using remote analytical techniques has the advantage of performing rapid chemical analysis of a variety of targets without sample collection. This saves significant time in planetary explorations using rovers and provides a large number of targets accessible to a lander near its landing site. The University of Hawaii (UH), in collaboration with Los Alamos...
