Episodicity within a mid-Cretaceous magmatic flare-up in West Antarctica: U-Pb ages of the Lassiter Coast intrusive suite, Antarctic Peninsula, and correlations along the Gondwana margin
Long-lived continental margin arcs are characterized by episodes of large-volume magmatism (or flare-ups) that can persist for ∼30 m.y. before steady-state arc conditions resume. Flare-up events ar ...
