Abstract

A forward sequence of folding is interpreted in the northwest Zagros fold belt using two new magnetostratigraphic studies to date non-marine foreland successions in the Afrineh and Chaman Goli growth synclines and integrating previous studies in the Lurestan and Fars arcs. The onset of growth is younger from the hinterland to the foreland and established at 13.5, 11.8, and 7.6 million years ago (Ma), spanning from Middle to Late Miocene, although the end of folding is in the Middle Pleistocene at about 1.5 Ma in the foreland front. In-sequence folding propagation toward the foreland occurred at a mean rate of 30 km/Myr with shortening rates of ≤1.9 mm/yr, using the onset of growth for Chaman Goli, Afrineh, and Changuleh well-dated synclines. The greater shortening of the Zagros continental collision occurred in its hinterland with continental overrriding of the Iranian block above the Arabian plate partially predating Neogene folding in the Zagros fold belt.
