Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Late Carboniferous igneous rocks are widespread in the western Tianshan, but the tectonic settings for these rocks remain controversial. We report a plagioclase 40Ar/39Ar age, and geochemical, Sr–Nd isotope and LA–ICPMS clinopyroxene trace element data ...

Neoproterozoic Gabbro and Diorites of the Tianquan County, Longmenshan Orogenic Belt, SW China: U-Pb Ages, Petrogenesis and Tectonic Settings [PDF]
Petrological and isotope-geochemical studies of magmatic rocks are a necessary part of most tectonic and metallogenic reconstructions, in particular, in orogenic belts formed at active margins of cratonic blocks that experienced long-term and ...

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...
