Thermal analyzes are used to characterize volatile-bearing materials, including minerals, pharmaceuticals, organic compounds, among others. The principle of analysis is heating the sample at a controlled rate and controlling its mass and enthalpy variations during heating. In mass variation analyzes (TG, thermo-gravimetric), the sample holder is coupled to a precision balance that records…
In the present work, samples of emeralds from Brazilian and Colombian deposits will be analyzed through multi-element chemical analysis by ICPMS laser ablation and complementary analyzes, such as Raman spectrometry and visible light spectrophotometry, in order to determine the chemical signature of the deposits of emeralds and identification of materials of unknown origin. Chemical data w…
Zeolites are secondary minerals common in volcanic rocks, widely distributed in the basalts of the Paraná Magmatic Province (PMP). Cavities in volcanic rocks are usually filled by complex secondary mineralogical assemblages, with several species of zeolites, in addition to chlorite, apophyllite, quartz, and calcite. Several authors have sought to correlate crystallization sequences of zeo…
Volcanic rocks of the Paraná Basin are an important information source about geological processes not completely understood yet, partly because there is no analogous volcanism in historical time that could be observed directly. While basaltic rocks are extensively studied in their various geological, petrological and geochemical aspects, acidic volcanic rocks are relatively less well know…
The materials discarded in the sand ports fine ponds are abundant environmental liabilities, even inert, occupy large volumes and need constant care. Domestic production of sand increased in recent years and the need to give a better destination for these wastes is being increased. The zeolite synthesis is made from the alkaline fusion with sodium hydroxide at 600 °C the thin material of …

The present scientific project with the Technical University of Munich aims to develop an analytical protocol for traceability of Brazilian and Colombian emeralds based on their chemical composition determined with a portable X-ray fluorescence spectrometer (p-XRF), which is a widely available equipment. Traceability of emeralds is done by comparing the minor and trace element signature o…
