Lithospheric extension associated with slab rollback: Insights from early Cretaceous magmatism in the southern segment of Tan-Lu fault zone, central-eastern China

The eastern China region underwent an intense lithosphere thinning event during Mesozoic but the mechanism for this process remains controversial. Here we investigate the Early Cretaceous Guandian intrusive complex in southern segment of the Tancheng-Lujiang (Tan-Lu) fault zone, central-eastern China, to gain insights into lithospheric extension and thinning. We present zircon UPb ages and LuHf isotope data, together with whole rock major and...
