Basaltic rocks exposed in the Shiting to Yinko area in northern Taiwan are considered to represent a member of the products of the Neogene intraplate volcanism in the Fujian-Taiwan region of the SE China continental margin. This paper presents new age dating, petrographic (including mineral chemistry) and geochemical data which suggest the existence of two groups of the basaltic rocks: the earl...

Abstract Several of Earth's intraplate volcanic provinces are hard to reconcile with the mantle plume hypothesis. Instead, they exhibit characteristics that more compatible shallower processes involve interplay between uppermost flow and base heterogeneous lithosphere. The mechanisms most commonly invoked edge‐driven convection (EDC) shear‐driven upwelling (SDU), both which act focus associated...

Abstract The upper mantle is heterogeneous in Fe isotope compositions, but the origin of heterogeneity needs understanding. Recent studies on oceanic basalts demonstrate that results from low‐degree melt metasomatism. However, whether this hypothesis global significance testing continental settings. Here we present an isotopic study intraplate alkali China, which are shown to have derived conta...
