文摘

The Caosiyao Mo deposit formed approximately 148 Ma ago. The Caosiyao complex consists of syenogranite porphyry and monzogranite porphyry. The formation age of the Caosiyao complex is between 140.1 and 148.5 Ma. The complex was formed by partial melting of a Paleoproterozoic lower crust. The Caosiyao complex was most likely formed in a post-orogenic setting.
