Geochronological, geochemical, whole-rock Sr–Nd and zircon Hf isotopic analyses have been carried out on two suites of Late Mesozoic mafic to felsic magmatic rocks in the Sulu orogenic belt (east-central China) with the aim of characterizing their petrogenesis and tectonic implications. The Shijiusuo monzogranite has a SHRIMP zircon 206 Pb/ 238 U age of 127±2 Ma and an 40 Ar/...
The Jiazishan alkaline complex in the eastern Sulu ultrahigh pressure (UHP) metamorphic orogenic belt of eastern China is composed of potassic to ultrapotassic pyroxene syenite, quartz syenite and associated mafic dikes. A SHRIMP zircon 206 Pb/ 238 U age of 215±5 Ma was obtained for the quartz syenite and mineral 40 Ar/ 39 Ar dating gave emplacement ages of 214.4±0...
