The Grenville orogeny involved the collision of a continent to the southern and eastern margins of North America during the period 1.3 to 1.1 billion years ago. Shortly after this collision, in the southwest United States, was a widespread magmatic event that resulted intrusions and lava flows. This study produced new ages on rocks in this magmatic province, named the Southwest Laurentia large igneous province, using the U-Pb decay scheme on a mineral called baddeleyite (ZrO2). The new ages suggest that this event is much shorter in duration than previously thought, lasting less than 20 million years from 1100 to 1080 million years ago. The cause of magmatism may have been the break-off of a subducting slab or a large mantle plume that split into two parts, one forming the Southwestern Laurentia large igneous province and the other responsible for the coeval magmatism in the Mid-Continent Rift exposed in the northern Midwest of the United States.


Two-stage development of the Paparoa Metamorphic Core Complex, West Coast, South Island, New Zealand: Hot continental extension precedes sea-floor spreading by -25 m.y.

Metamorphic core complexes can be precursors of continental breakup and result from extreme extension where the lower crust is dragged to the surface below large-scale extensional faults. The Paparoa Metamorphic Core Complex (PCC) on the West Coast of the South Island in New Zealand developed in the mid-Cretaceous and conditioned the crust for the eventual breakup of the Gondwana Pacific margin and formation of the Tasman Sea. The PCC has two detachment systems with opposite senses of shear: a top-to-the-NE detachment in the north and a to
