Isotopic Evidence for Multiple Recycled Sulfur Reservoirs in the Mangaia Mantle Plume
Autor: J. W. Dottin III, J. Labidi, M. G. Jackson, J. Woodhead, J. Farquhar
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 21, Iss 10, Pp n/a-n/a (2020)
Abstract Mangaia, an ocean island in the Cook‐Austral volcanic chain, is the type locality for the HIMU mantle reservoir and has also been shown to exhibit evidence for recycled sulfur with anomalous δ34S and Δ33S that has been attributed an Arch

Sulfur isotope evidence of geochemical zonation of the Samoan mantle plume
Autor: Matthew G. Jackson, Jabrane Labidi, James Farquhar, J. W. Dottin
The radiogenic Pb isotope compositions of basalts from the Samoan hotspot suggest various mantle endmembers contribute compositionally distinct material to lavas erupted at different islands [1]. Basalts from the Samoan islands sample contributions f

Evidence for oxidation at the base of the nakhlite pile by reduction of sulfate salts at the time of lava emplacement
Autor: Philip M. Piccoli, J. W. Dottin, Kevin D. McKeegan, Ming-Chang Liu, James Farquhar, Jabrane Labidi
Publikováno v: Geochimica et Cosmochimica Acta. 239:186-197
The assimilation of sulfate by Martian melts could explain the highly oxidized state of some Martian nakhlite meteorites, such as those paired with MIL 03346 (MIL 090030, MIL 090032, and MIL 090136). Here, a combination of new sulfur isotope data, mi

Sulfur isotope signatures of eucrites and diogenites
Autor: James Farquhar, Nanping Wu, Nivea Magalhães, J. W. Dottin
Publikováno v: Geochimica et Cosmochimica Acta. 233:1-13
High precision sulfur isotope data on eight eucrites and two diogenites are reported to explore the provenance of sulfur and processes that affected the sulfur isotope composition and sulfur abundance within the HED ( H owardite, E ucrite, D iogenite

Multiple sulfur isotopic composition of main group pallasites support genetic links to IIIAB iron meteorites
Autor: James Farquhar, J. W. Dottin, Jabrane Labidi
Publikováno v: Geochimica et Cosmochimica Acta. 224:276-281
This study reports the quadruple sulfur isotope composition of troilite nodules from Main Group Pallasites. Values range from −0.23‰ to 0.34‰ (average = 0.03 ± 0.17‰ S.D.) in δ34S and 0.008‰ to 0.025‰ (average = 0.018 ± 0.006‰ S.D.)
