Type I is composed of rhyolitic rocks, which are characterized by higher Si and alkali contents and lower Al and Ti contents, Na2O/K2O1 and a weak negative Eu anomaly (δEu=0.65–0.95), enriched in Sr and Ba and poor in Rb. Types I and II probably formed in an extensional to postorogenic extensional environment, accompanied by compressional uplift.
