Pre‐eruption magma staging at the long‐lived intraplate Dunedin Volcano, New Zealand

The oldest-known rocks of the eroded Dunedin Volcano (DV), New Zealand, active 16.0–11.0 Ma, were emplaced by penecontemporaneous explosive eruptions and intrusions magmas with a remarkable range compositions, including basanite, alkali basalt, trachyte phonolite. compositional diversity in rapid succession during earliest development volcano signify existence complex magmatic system highly evolved magmas, typical those attributed to mature systems; here it developed concert volcano's surface eruptions. We infer that multiple deep shallow reservoirs suddenly tapped as volcanism commenced. DV repeatedly erupted same over 5 Myr, suggests these distributed failed significantly integrate through millions years slow growth.
