Protocols for in situ measurement of oxygen isotopes in goethite by ion microprobe
(Elsevier B.V., 2020-02-05)
We present protocols for high-spatial resolution measurement of oxygen isotope ratios of goethite (alpha-FeOOH) with the Sensitive High Mass Resolution Ion Microprobe - Stable Isotopes (SHRIMP-SI) and propose a natural ...
Millimeter length micromachining using a heavy ion nuclear microprobe with standard magnetic scanning
(Elsevier Science, 2013-02)
In order to increase the scanning length of our microprobe, we have developed an irradiation procedure suitable for use in any nuclear microprobe, extending at least up to 400% the length of our heavy ion direct writing ...
U-Pb SHRIMP dating of basement rocks of the Iriri-Xingu domain, Central Amazonian province, Amazonian craton, Brazil

Neoproterozoic backarc basin: Sensitive high-resolution ion microprobe U-Pb and Sm-Nd isotopic evidence from the Eastern Pampean Ranges, Argentina
(Geological Society of America, 2007-06)
The Eastern Pampean Ranges comprise high-grade supracrustal sequences with linear belts of mafic-ultramafic bodies representing ophiolite remnants. New U-Pb and Nd isotopic data suggest that the tectonic evolution of the ...

Comparative Lower-Middle Ordovician conodont oxygen isotope palaeothermometry of the Argentine Precordillera and Laurentian margins
(Elsevier Science, 2020-07)
Stratigraphic, palaeontologic, and palaeomagnetic data support a hypothesis that argues for the Argentine Precordillera rifting from the southwestern margin of Laurentia in low latitudes during the Cambrian, migrating ...
