... magmatism of the Guara-Pará and Serra Azul complexes. The granitoids can be grouped into (1) sodic magmatism composed of TTG-affinity Mogno trondhjemite and Arco Verde and Mariazinha tonalites and (2) calcic-alkaline magmatism represented by the high-Mg Rio Maria sanukitoid suite, the high Ba-Sr Guarantã...

.... Our alternative Appalachian model improves the fit of synthetics to data for five of the ten paths modeled in that province. From the results, we identify two specific sources of wave-field complexities that should be investigated in future studies of earthquake ground motions in NEUS : 3% azimuthal...

... Hill anticlinorium along the northeastern margin of the basin. The K-feldspar grains came largely from pegmatites, and perhaps high levels now eroded of the quartz monzodiorite gneiss of the Devonian Belchertown igneous complex intruded during the Acadian orogeny. Sodic plagioclase grains were...
