Geochronology and geochemistry of the Carboniferous magmatism in the northern Great Xing’an Range, NE China: Constraints on the timing of amalgamation of Xing’an and Songnen blocks

The Carboniferous period marks an important transition from accretion to collision in the Great Xing’an Range, NE China. In this study we present new data to provide a better constraint on the magmatic process in the studied area during this period and its implications for the regional tectonic evolution in the eastern Central Asia Orogenic Belt. The new age data we report consist of zircon SIMS U–Pb ages of 306–315 Ma and zircon LA-ICP-MS U–Pb...
