Discussion

New Guinea, which is actually the northern tip of the Australian Plate, is the pre-eminent example in the world of terrane accretion. The "tail" of New Guinea is actually a recently-accreted terrane, and the Solomon and New Hebrides Islands are impending terrane accretions.

The jammed-up terranes are clogging the subduction zone, and seismic evidence suggests the corner of the Pacific Plate is beginning to break along the dotted blue line.
