The Petrogenesis of Early Paleozoic high-Ba-Sr Intrusions in The North Qinling Terrane, China, and Tectonic Implications by renee is a document available to read on EtoBox.
This study investigates the petrogenesis of early Paleozoic high-Ba–Sr intrusions in the North Qinling terrane, China, focusing on three dioritic intrusions with new geochronological and geochemical data. The K-rich intrusions formed in a slab subduction setting around 439-438 Ma, while the Na-rich intrusion was influenced by slab break-off around 429-425 Ma, indicating complex tectonic processes during the Paleozoic era. The findings suggest that the closure of the Shangdan Ocean and the collision between
