the study area is a part of the sanandaj-sirjan metamorphic belt comprising low- to high-graderegional and contact metamorphic rocks that are intruded by various plutonic bodies. garnet crystals areabundant in pelitic schists, amphibole schists, migmatites, hornfelses and aplites. they are mostly almandinerich(xalm>60) pyralspite garnets and show dodecahedron, trapezohedron and mixed (dodecahed...

The geographic distribution of elevated groundwater As concentrations in a fractured silicate bedrock aquifer in central New Hampshire correlates with the presence of pegmatites which border late Devonian granites and intrude metasedimentary rocks. As concentrations in the pegmatites averaged 9.6 mg/kg, which is much higher than the associated granites (0.24 mg/kg) and metasedimentary rocks (0....
