Postcollisional transition from subduction- to intraplatetype magmatism in the eastern Sakarya zone, Turkey: Indicators of northern Neotethyan slab breakoff
(Geological Soc Amer, Inc, 2019)Postcollisional magmatism in the eastern Sakarya zone was recorded by voluminous basic volcanism and repeated plutonism during the early Cenozoic. the temporal and geochemical evolution of these magmatic rocks is important ... -
Tracking the birth and growth of Cimmeria: Geochronology and origins of intrusive rocks from NW Iran
(Elsevier, 2020)New geochronological and geochemical data for Late Neoproterozoic to Mesozoic intrusive rocks from NW Iran define major regional magmatic episodes and track the birth and growth of one of the Cimmerian microcontinents: the ... -
The Paleogene ophiolite conundrum of the Iran-Iraq border region
(Geological Soc Publ House, 2020)New and compiled geochemical, isotopic and geochronological data allow us to propose a new explanation for Paleogene oceanic magmatic rocks along the Iran-Iraq border. These rocks are represented by a thick pile (>1000 m) ... -
Reply to the discussion by Granier of Vincent et al., (2018) (Marine and Petroleum Geology, 91, 639-657)
