Geochemical data on the late-Cretaceous primitive intraoceanic arc lavas of the Olyutorsky terrain ...
This dataset comprises the analyses of the intraoceanic arc rocks of the Olyutorsky terrain: major elements, minor elements, platinum-group elements, Rb-Sr, Sm-Nd, Lu-Hf and Pb-Pd isotopic systems. Samples are late Cretaceous in age and comprise picrites from the Tumrok and Valaginsky Ranges, and pi...

Summary: | This dataset comprises the analyses of the intraoceanic arc rocks of the Olyutorsky terrain: major elements, minor elements, platinum-group elements, Rb-Sr, Sm-Nd, Lu-Hf and Pb-Pd isotopic systems. Samples are late Cretaceous in age and comprise picrites from the Tumrok and Valaginsky Ranges, and picrites, magnesian basalts and basalts from the Koryak Highlands. Major elements were measured by XRF, minor/trace elements by ICP-MS at the University of Tasmania (in 2019) and the Russian Geological Institute (in 2015); platinum-group elements were measured by ICP-MS using the Ni sulfide fire assay-isotope dilution method at the Seoul National University. Radiogenic (Sr-Nd-Hf-Pb) isotope compositions were determined at the University of Melbourne and the Institute of the Earth’s Crust, Irkutsk, using multi-collector ICP-MS in 2019. A subset of these data were originally published as a supplement to Kutyrev et al. (2021), Primitive high-K intraoceanic arc magmas of Eastern Kamchatka: Implications for Paleo-Pacific ... : The DIGIS geochemical data repository is a research data repository in the Earth Sciences domain with a specific focus on geochemical data. The repository archives, publishes and makes accessible user-contributed, peer-reviewed research data in standardised form (EarthChem Team, 2022) that fall within the scope of the GEOROC database. All submissions of new data will be considered for inclusion in the GEOROC database. It is hosted at GFZ Data Services through a collaboration between the Digital Geochemical Data Infrastructure (DIGIS) for GEOROC 2.0 (http://digis.geo.uni-goettingen.de) and the GFZ German Research Centre for Geosciences. ... |
