Age of the amur group of the Bureya-Jiamusi Superterrane in the Central Asian fold belt: Sm-Nd isotope evidence

The rocks of the Amur Group are metamorphosed to epidoteamphibolite and amphibolite facies.The group is traditionally considered to be the Late Archean in age, although no data for or against this viewpoint are available so far.

Zusammenfassung:The rocks of the Amur Group are metamorphosed to epidoteamphibolite and amphibolite facies.The group is traditionally considered to be the Late Archean in age, although no data for or against this viewpoint are available so far. For solving this prob lem, we performed SmNd isotopic geochemical studies of clastic metasedimentary rocks constituting this unit.
