An automated iridium-strip heater for LA-ICP-MS bulk analysis of geological samples
(Wiley-blackwellHobokenEUA, 2008)
Time lag between metamorphism and crystallization of anatectic granites (Córdoba, Argentina)
(Universidad de Barcelona, 2020-11)
SHRIMP and LA-ICP-MS analyses carried out on zircons from the Río de los Sauces granite revealed their metamorphic and igneous nature. The metamorphic zircons yielded an age of 537±4.8 (2σ)Ma that probably predates the ...

In situ Sr isotope analyses by LA-MC-ICP-MS of igneous apatite and plagioclase from magmatic rocks at the CPGeo-USPMicroanálises isotópicas de Sr de plagioclásio e apatita magmáticos via LA-MC-ICP-MS no CPGeo-USP
(Sociedade Brasileira de Geologia, 2016-06)
This contribution describes the successful implementation of in situ Sr isotope analyses by LA-MC-ICP-MS at the CPGeo-USP. The choice for an analytical configuration using measurements of half-masses allows the accurate ...
