Cretaceous intracontinental rifting at the southern Chatham Rise margin and initialisation of seafloor spreading between Zealandia and Antarctica
Passive continental margins are commonly classified as magma-poor and magma-rich
types. Related breakup processes are often associated with far-field tectonic stresses or …
