RESUMEN. Este estudio investiga el potencial de los biomarcadores (levoglucosano y galactosano) como indicadores indirectos de la actividad de los incendios forestales en la Amazonia y Bolivia, utilizando muestras obtenidas en la estación Chacaltaya Global Atmosphere Watch (GAW), situada en la región de los Andes Tropicales. Los análisis preliminar...
Este estudo investiga o potencial de biomarcadores (levoglucosan e galactosan) como proxies para a atividade de incêndios florestais na Amazônia e na Bolívia, utilizando amostras obtidas da estação Chacaltaya Global Atmosphere Watch (GAW) situada na região dos Andes Tropicais. Análises preliminares exploram as associações entre esses biomarcadores...
Insoluble particles in ice cores record signatures of past climate parameters like vegetation dynamics, volcanic activity, and aridity. For some of them, the analytical detection relies on intensive bench microscopy investigation and requires dedicated sample preparation steps. Both are laborious, require in-depth knowledge, and often restrict samp...

Dust particle studies in ice cores from the tropical Andes provide important information about climate dynamics. We investigated dust concentrations from a 22.7 m ice-core recovered from the Quelccaya Ice Cap (QIC) in 2018, representing 14 years of snow accumulation. The dust seasonality signal was still preserved with homogenization of the record...

This work investigated the origin and evolution of chloritites and chlorite bearing rocks and Cu-Fe sulfides, associated with sill
and apophysis of the Caçapava Granite, which intrude in the dolomitic marbles of the Passo Feio formation, Terrane São Gabriel
of the Sul-Riograndense Shield. The interaction of the granite fluids with the marbles gener...
RESUMO: Diversas ocorrências de mármores do Escudo Sul-Rio-Grandense estão intrudidas por rochas granitóides e/ou vulcânicas do Ciclo Brasiliano. A interação dos fluidos magmáticos com as rochas carbonáticas do escudo gera escarnitos com diferentes padrões e zonações mineralógicas, frequentemente associados com sulfetos de Cu, Fe (Au) e/ou Pb-Zn. I...
Os mármores calcíticos de Vila Nova do Sul, pertencentes ao complexo Cambaizinho no Bloco São Gabriel apresentam uma variedade de domínios mineralógicos derivados de reações formando paragêneses específicas devido à interação de fluidos de origem magmática com a rocha encaixante carbonática. Duas situações bem distintas ocorrem na área: uma paragên...
As rochas carbonáticas do embasamento do Rio Grande do Sul estão encaixadas em sequências vulcano-sedimentares ou gnaisses quartzo-feldspáticos de idade Pre-Cambriana. Invariavelmente as diferentes ocorrências de sequencias carbonáticas do Escudo Sul Rio-grandense estão afetadas pelo metamorfismo orogênico desde o grau muito-baixo até o grau alto,...
Resumo -O Bloco São Gabriel, localizado na zona central do embasamento cristalino do Rio Grande Sul, apre-senta extensos registros do Neoproterozóico do Ciclo Brasiliano, contidos em complexos ígneos e metamórfi-cos. Esses complexos também guardam registros sedimentares, com sequências carbonáticas metamorfisadas, cuja evolução tectônica é pouco co...
C, Sr and O isotopic compositions and ree geochemistry of São Gabriel Block carbonate rocks, Rio Grande do Sul. The São Gabriel Block, located in the central zone of the crystalline basement in the state of Rio Grande do Sul has extensive Neoproterozoic records of the Brasiliano Cycle, recorded in igneous and metamorphic complexes. These complexes...
