文摘
Cenozoic alkaline volcanoes, PNG, sit atop submarine ridges due to plate flexure.
Alignment of the narrow 250 km long volcanic arc is orthogonal to ridges.
Linear volcanic arc suggests ascent of alkaline magmas in arc-parallel fractures.
Volcanism was localized at intersection of arc- and ridge-parallel structures.
Unique volcano-tectonic history is key to origin of Earth's largest gold deposit.
