Post-collisional lithosphere delamination of the Dabie-Sulu orogen

Chinese Science Bulletin, 2002
The consistence between the first rapid cooling time (226–219 Ma) of the untrahigh pressure metamorphic (UHPM) rocks in the Dabie Mountains and the formation time (205–220 Ma) of the syncollisional granites in the Qinling and Sulu areas suggests that the first rapid cooling and uplift of the UHPM rocks may be related to breakoff of subducted plate ...

Disclosing the Paleoarchean to Ediacaran history of the Sao Francisco craton basement: The Porteirinha domain (northern Aracuai orogen, Brazil)

, 2016
This geochronological and isotopic study focuses on one of the Archean-Paleoproterozoic basement domains of the Sao Francisco craton reworked in the Araçuaí orogen, the Porteirinha domain, Brazil.

Zircon U-Pb Dating of the Irizar Granite in the Central Victoria Land, Antarctica: Insights into the Tectonic Evolution along the Ross Orogen

It has been accepted that granitoids of the Irizar unit in the Central Victoria Land (Antarctica), as an important part of the Granite Harbour Intrusives, were formed in a post-collisional setting during the Ross orogeny along the margin of east Gondwana.

Metamorphic record of collision and collapse in the Ediacaran-Cambrian Araçuaí orogen, SE-Brazil: Insights fromP-Tpseudosections and monazite dating

, 2017
he Araçuaí orogen is the Brazilian counterpart of the Araçuaí‐West Congo orogenic system (AWCO), a component of the Ediacaran‐Cambrian orogenic network formed during the amalgamation of West Gondwana.

The Miocene Gangdese porphyry copper belt generated during post-collisional extension in the Tibetan Orogen

, 2009
The mid-Miocene Gangdese orogenic belt in southern Tibet contains porphyry Cu deposits that developed after the Indian-Asian continental collision in the early Cenozoic.

Thermobarometry and electron-microprobe Th-U-Pb monazite dating in garnet metapelites from the Capelinha Formation, Araçuaí Orogen, Brazil.

, 2016
The Capelinha Formation (Macaúbas Group) consists of a lower quartzitic unit with metamafic intercalations and an upper metapelitic sequence. It occurs in a complex tectono-metamorphic sector of the Araçuaí orogen, where post-collisional collapse-related

Massive crustal carbon mobilization and emission driven by India underthrusting Asia

Communications Earth & Environment
The active Himalayan-Tibetan orogen, where India underthrusts into Asia, is an important geological source of carbon dioxide (CO2) emission into Earth’s atmosphere.

Crust‐Mantle Interaction During Continental Deep Subduction: Evidence From Light Mo Isotopes in Post‐Collisional Mafic Igneous Rocks From the East Kunlun Orogen

Geochemistry, Geophysics, Geosystems
It is intriguing whether and how crust‐mantle interaction would proceed in continental subduction zones. Here, we report zircon U‐Pb ages and Hf isotopes, major and trace elements, and Sr‐Nd‐Mo isotopes for Late Paleozoic mafic igneous rocks from the ...

Lithospheric structure and geologic development of a collisional orogen: Insights from the central Alaska Range

, 2012
The long-term distribution, mode, and progression of deformation along a collisional boundary are all fundamental, though poorly understood, processes of convergent margins.
