Abstract

Ages of late Mesozoic-early Cainozoic igneous rocks in south-western North America indicate a magmatic arc initiated near the continental margin, swept over 1,000 km northeastward, then swept back, all in 110 Myr. The sweep in and return are interpreted as due to flattening of a Benioff zone to < 15°followed by rapid collapse.
