Geochemistry
Coordination: Pedro Ferreira, LNEG
Institutions: FCUL, FCUP, FEUP, LNEG, UA
Data and Services:
. Quantification of major and trace elements, by X-Ray Fluorescence (complemented by loss on ignition determination)
. Identification of unknown crystalline materials (e.g., minerals, inorganic compounds), by X-Ray Diffraction
. Punctual (at the 1-10 micrometer scale) chemical characterization of geological materials (minerals, fused beads/pearls of rock samples), by electron microprobe
. Determination of 87Sr/86Sr isotopic ratios in waters, silicate rocks, carbonated rocks and fossil material, including sample digestion and chromatography separation. Measurement of Rb and Sr concentrations in rocks and minerals, by isotopic dilution. All measurements by Thermal Ionization Mass Spectrometry (TIMS)
. Determination of the 143Nd / 144Nd ratio, including sample digestion and chromatographic separation, as well as Sm and Nd concentrations in rocks, by isotopic dilution. All measurements by Thermal Ionization Mass Spectrometry (TIMS)
. Separation, identification and quantification of organic compounds, by Gas Chromatography-Mass Spectrometry (GC-MS)
. Chemical analysis of rocks, incl. Si, Ag, Cd, Cr, Co, Ni, Fe, K, Na, K, Pb, Sn, Al, Cu, U, Mn, Mo, Zn, In, As, W, Au, Li, Ga by Atomic Absorption Spectroscopy (AAS)
