Crustal xenoliths embedded in lavas offer chances to provide information on the lithology of the volcano basement and the process occurring during magma ascent. In this work we studied seven xenoliths found among the scoriae ejected during several paroxys... see more

Quartz-rich xenoliths in lavas (basalts to andesites; 90-30 ka) from Alicudi contain abundant melt and fluid inclusions. Two generations of CO2-rich fluid inclusions are present in quartz-rich xenolith grains: early (Type I) inclusions related to partial ... see more

The Pelotas Batholith situated in the eastern part of Sul-rio-grandense Shield is NE oriented and has dimensions of about 400 x 120 km. It is a granitic belt with six main suites: Pinheiro Machado Suite, Erval Suite, Viamão Suite, Encruzilhada do Sul Suit... see more

The Paraná-Etendeka Continental Flood Basalt province hosts world-class agate and amethyst geode deposits in Rio Grande do Sul (Brazil; Serra Geral Fm.). Salto do Jacuí Mining District (Rio Grande do Sul, Brasil) has different types of agate geode hosted ... see more

Com o advento de novas tecnologias, a geologia avançou em seu conhecimento. E técnicas de sensoriamento remoto como magnetometria, imagens de satélite Landsat 8 e dados TOPODATA, que são geoprocessados em diferentes softwares como o Quantum Gis permitiram... see more

In San Martín de los Andes area (Argentinian Patagonia) the Palaeozoic basement consists of metamorphic and plutonic rocks. The metamorphic rocks include strongly deformed schists, gneisses and migmatites. Their geochemical and petrographic characteristic... see more

Post-crystallization evolution of the metatroctolites of the Lago Ñorquinco zone, Aluminé Igneous-Metamorphic Complex, is analyzed. These mafic rocks show coronas around olivine, composed of Opx, Cpx, Spl and Amp (Hbl1 and Hbl2). The temporal evolution of... see more

The processes associated with the interaction between the Pinchal Granodiorite (PG) and the kilometric Cerro Negro Xenolith (KCNX) are studied. The PG was cooled during the Late Carboniferous, whereas the age of the KCNX remain until now unknown. The KCNX... see more
