Together with whole-rock and isotope geochemistry for the igneous rocks from the c[...]texto impreso
Alasino, Pablo H. ; Casquet, César ; Galindo Francisco, Mª del Carmen ; Pankhurst, R.J. ; Rapela, Carlos W. ; Dahlquist, Juan A. ; Recio, C. ; Baldo, Edgardo G. ; Larrovere, Mariano Alexis ; Ramacciotti, Carlos | Cambridge University Press | 2020We report a study of whole-rock O–H–Sr–Nd isotopes of Ordovician igneous and metamorphic rocks exposed at different crustal palaeodepths along c. 750 km in the Sierras Pampeanas, NW Argentina. The isotope compositions preserved in the intermedia[...]texto impreso
