Multi-method chronometric constraints on the evolution of the Northern Kyrgyz Tien Shan granitoids (Central Asian Orogenic Belt): From emplacement to exhumation

Multichronological data reveal the thermotectonic history of the northern Kyrgyz Tien Shan granitoids (Kyrgyzstan) from emplacement to exhumation. Zircon SHRIMP and LA-ICP-MS U/Pb concordia ages suggest a Middle to Late Ordovician crystallization age (440–470 Ma) for the most voluminous; Caledonian intrusion phase, which is associated with the evolution and closure of the Early Palaeozoic Terskey Ocean. The presence of some additional Early...
