The “Cretaceous oceanic red beds (CORBs)” associated with “oceanic oxic events” have become a hot topic for geologists from around the world. In southern Tibet, the CORBs are widely distributed in the Upper Cretaceous of the northern Tethys Himalayas, but they have never been reported from the southern Tethyan Himalaya (Tibet, China).

The plagiogranites in ophiolites are minor in volume but can provide crucial information for the origin and tectonic evolution of ancient oceanic lithosphere. This paper presents the geochronology and geochemistry of a newly discovered plagiogranite in the Shiquanhe ophiolite, from the west end of the Shiquanhe‐Jiali ophiolite sub‐belt, Bangong Suture, central Tibet. Zircon U–Pb dating of two samples...
