Process of ophiolite emplacement in Oman and Newfoundland

Abstract

The Semail Ophiolite in the Sultanate of Oman, and the Bay of Islands and St. Anthony Ophiolite Complexes in western Newfoundland show a similar multistage history of ophiolite obduction. This involved both intra-oceanic detachment of the ophiolite slabs and their emplacement onto the continental margin. Structural relations within these examples clearly indicate a complex scenario of assembly which involved initial delamination between the drift and rift facies segments of the continental margin sequence followed by major break-back (out-of-sequence) thrusting. -from Authors
