Generation of Tonalitic and Dioritic Magmas by Coupled Partial Melting of Gabbroic and Metasedimentary Rocks within the Deep Crust of the Famatinian Magmatic Arc, Argentina

Genetic implications of new Sr and Nd isotopic data of the intrusive rocks from the Laramide Arc in Northern Sonora, Mexico.

“…The Sr isotopic ratios of standards and samples were normalized to 86 Sr/ 88 Sr = 0.1194, whereas the Nd isotopic ratios were normalized to 146 Nd/ 144 Nd = 0.7219. The estimated analytical + 2s uncertainties are similar to those reported in Ducea et al (2002) and Otamendi et al (2009 Nd for the La Jolla Nd standard were 0.511853±2 (n=10). We also note that our results were not adjusted to any accepted values for these standards.…”

Formation and Evolution of the Continental Crust

“…For example, it is the standard model for granitic magmatism in the Andes (e.g., Hildreth and Moorbath, 1988;Kay and Mahlburg-Kay, 1991;Petford et al, 2000;Otamendi et al, 2009;Goss et al, 2011), as well as for ancient island arcs such as those exposed in crustal sections in Pakistan (Jagoutz, 2010;Jagoutz et al, 2011Jagoutz et al, , 2013. There is also growing support for the generation of Archean TTG in such a setting (e.g., Polat et al, 2002;Nagel et al, 2012;Polat, 2012).…”

The evolution of a key segment in the Europe–Adria collision: The Fruška Gora of northern Serbia

“…Both samples are located in the vicinity of the detachment separating the metamorphic core from the flanking sedimentary cover. The spatially-controlled sampling was achieved under microscopic view using a Mass spectrometric analyses were carried out at the University of Arizona on an automated VG Sector multicollector instrument fitted with adjustable 1011 Faraday collectors and a Daly photomultiplier(Otamendi et al, 2009). Concentrations of Rb and Sr were determined by isotope dilution, with isotopic compositions determined on the same spiked runs.…”
