U–Pb Isotope and REE Composition of Zircon from the Pyroxene Crystalline Schists of the Irkut Terrane, Sharyzhalgai Uplift: Evidence for the Neoarchean Magmatic and Metamorphic Events

Turkina O.M.; Berezhnaya N.G.; Urmantseva L.N.; Paderin I.P.; Skublov S.G. (2009)

The Early Precambrian granulite-gneissic complexes are typically characterized by a long evolutionary history, which involves formation of their protoliths and repeated metamorphism related mainly with collisional events. ...
ZIRCON TRACE ELEMENT GEOCHEMISTRY: PARTITIONING WITH GARNET AND THE LINK BETWEEN U-PB AGES AND METAMORPHISM

Rubatto D. (2002)

With the aim to link zircon composition with paragenesis and thus metamorphic conditions, zircons from eclogite- and granulite-facies rocks were analysed for trace elements using LA-ICP-MS and SHRIMP ion microprobe. ...
Zircon U–Pb and Hf isotopic study of gneissic rocks from the Chinese Altai: Progressive accretionary history in the early to middle Palaeozoic

Sun M.; Yuan C.; Xiao W.; Long X.; Xia X.; Zhao G.; Lin S.; Wu F.; Kröner A. (2008)

Gneissic rocks in the Chinese Altai Mountains have been interpreted as either Paleozoic metasedimentary rocks or Precambrian basement. This study reports geochemical and geochronological data for banded paragneisses and ...
