A summary of the geology of the Iranian Makran

Abstract

The Iranian Makran has been entirely mapped geologically on a scale of 1:250 000

Geochemistry and geochronology of thevolcano-plutonic rocks associated with the Glojehepithermal gold mineralization, NW Iran

“…The Tethyan orogen formed following the collision of Eurasia with dispersed fragments of Gondwanaland [13,14], and rifting from the Late Palaeozoic to Early Mesozoic formed ribbon fragments of continental crust that broke away from the northern margin of Gondwanaland to form the Tethys Ocean. There were two successive Tethyan oceans [15][16][17][18][19][20][21][22][23][24][25][26][27][28], the northern, older Paleo-Tethys ocean separated the Iranian plate from Eurasia during Late Paleozoic to Early Mesozoic times. The southern, younger Neo-Tethys ocean was located between the Iranian and Arabian plates during Late Mesozoic times [29].…”

Review of the tectonic setting of Cretaceous to Quaternary volcanism in northwestern Iran

“…Iran, Alborz, Kopeh Dagh, and eastern Iran (for more information see Falcon, 1967;Stocklin, 1968;Dewey et al, 1973;Sengor, 1984;Jackson and McKenzie, 1984;Byrne et al, 1992;McCall, 2002;Allen et al, 2003;Blanc et al, 2003;Walker and Jackson, 2004;Alavi, 2004).…”

Effects of mass waste events on thrust wedges: Analogue experiments and application to the Makran accretionary wedge

“…The Paleogene units of the northern Makran are characterized by large thrusts and strong internal deformation of thrust units expressed by tight folds and associated axial plane cleavage [McCall, 2002;Burg et al, 2008]. Thrust activity in northern Makran started in the early Miocene and continued into the Quaternary, both in the Pakistani [Ellouz-Zimmermann et al, 2007a] and Iranian (our personal observations, 2005-2009) parts.…”

“…The olistostrome locally shows a weak cleavage but is much less intensely deformed than the older units it has unconformably covered. The dominantly Miocene and younger units of the Coastal Makran are deformed into large-wavelength-smallamplitude folds [McCall, 2002;Burg et al, 2008]. Axial plane cleavage is generally absent as are large displacements along thrusts [Burg et al, 2008].…”
