“…The evolution of magmatism in the Makran Terrane has progressed by northward subduction of the Arabian Platform under the Lut Terrane (Farhoudi and Karig, 1977) with temporal variations in slab dip (Shahabpour, 2010). From the Middle Jurassic to the early Paleocene, a steep-dip slab produced a continental arc in the Sanandaj-Sirjan Terrane.…”

“…However, no porphyry systems have positively been identified to date in this otherwise permissive island-arc setting (Walther, 1960;Samani, 1998;Förster, 1978;Shahabpour, 2010;Bazin and Hübner, 1969a). As in the Sanandaj-Sirjan Terrane to the west, Late Cretaceous-late Eocene igneous rocks in this fold-and-thrust belt appear deeply exhumed.…”

“…This oceanic terrane includes offshore island arcs that during this time were converging northward toward the East-Central Iranian, Farah, and Helmand Terranes (McCall, 1997;Shahabpour, 2010;. By the late Eocene, the Makran Terrane began to accrete with the Eurasian margin on the north, as well as with the converging Sanandaj-Sirjan Terrane on the west ( fig.…”

These fore-arc rocks are represented by Late Cretaceous marine sediments and tholeiitic ocean floor basalts and associated economic chromite deposits.…”

“…From the Middle Jurassic to the early Paleocene, a steep-dip slab produced a continental arc in the Sanandaj-Sirjan Terrane. This arc continues into the Makran Terrane where it is preserved in the BajganDurkan continental sliver that is wedged between the Jaz Murian Depression to the north and the Makran accretionary prim to the south (McCall, 1997;Shahabpour, 2010;Leturmy and Robin, 2010;Kazmin and others, 1986).…”

Jurassic rifting at the Eurasian Tethys margin: Geochemical and geochronological constraints from granitoids of North Makran, southeastern Iran

et al. 2015

View full text Add to dashboard Cite

This study focuses on an east-west trending belt of granitic to intermediate intrusions and their volcanic cover in the northern Dur Kan Complex, a continental slice outcropping to the north of the exposed Makran accretionary wedge in southeastern Iran. Field observations, petrographic descriptions, trace element, and isotope analyses combined with U-Pb zircon geochronology are presented to determine the time frame of magmatism and tectonic setting during the formation of these rocks. Results document three magmatic episodes with different melt sources for (1) granites, (2) a diorite-trondhjemite-plagiogranite sequence, and (3) diabases and lavas. Granites, dated at 170-175 Ma, represent crystallized melt with a strong continental isotopic contribution. The diorite-trondhjemite-plagiogranite sequence is 165-153 Ma old and derives from a mantle magma source with minor continental contribution. East-west trending diabase dikes and bodies intruded the granitoids, which were eroded and then covered by Valanginian (140-133 Ma) alkaline lavas and sediments. Alkaline dikes and lavas have a mantle isotopic composition. Temporal correlation with plutonites of the Sanandaj-Sirjan Zone to the northwest defines a narrow, NW-SE striking and nearly 2000 km long belt of Jurassic intrusions. The increasing mantle influence in the magma sources is explained by thinning of continental lithosphere and related mantle upwelling/decompression melting. Accordingly, the formation of the studied igneous rocks is related to the extension of the Iranian continental margin, which ultimately led to the formation of the Tethys-related North Makran Ophiolites.

Tectonic implications of the geochemical data from the Makran igneous rocks in Iran

Abstract: Makran is one of the largest accretionary prisms on Earth, formed by the closure of the Neotethys ocean which is now represented by its remnant, the Gulf of Oman.
