COMPARISON OF DEEP CRUSTAL COMPOSITIONS BETWEEN THE QINLING-DABIE OROGEN (CHINA) AND CENTRAL ASIAN OROGENIC BELT AND IMPLICATIONS FOR UNDERSTANDING ACCRETIONARY AND COLLISIONAL OROGENIC PROCESSES [PDF]

Геодинамика и тектонофизика, 2017
It is generally considered that there are different continental compositions between a subductional– collisional and an accretionary orogen, however, what are the differences and how to identify them has not been well understood.

A non‐collisional, accretionary Sveconorwegian orogen – Comment

Terra Nova, 2013
In a stimulating contribution, Slagstad et al. (2013) propose to interpret the 500-km-wide Sveconorwegian orogen in Scandinavia as a non-collisional, accretionary orogen. They challenge the more widely held view that it is the product of a late Mesoproterozoic to early Neoproterozoic continent–continent collision, formed during welding of ...

BRYANSK-KURSK-VORONEZH INTRA-CONTINENTAL COLLISIONAL OROGEN (EAST EUROPEAN CRATON) [PDF]

Геодинамика и тектонофизика, 2015
The article presents new data on the deep crustal structure, origin and evolution of the Bryansk-Kursk-Voronezh orogen in the south-eastern segment of the East European craton; it is composed of the Paleoproterozoic formations and areas of reworked ...

PALEOZOIC GRANITOID MAGMATISM OF THE URALS: THE REFLECTION OF THE STAGES OF THE GEODYNAMIC AND GEOCHEMICAL EVOLUTION OF A COLLISIONAL OROGEN [PDF]

Геодинамика и тектонофизика, 2021
The Ural mobile belt is an intracontinental epioceanic orogen that has already gone through all stages of the geodynamic development. Igneous rocks formed during each stage are important indicators for understanding the evolution of this belt and ...

The Alps in the Cretaceous: a doubly vergent pre‐collisional orogen

Terra Nova, 2012
Terra Nova, 24, 351–356, 2012AbstractCurrent palaeotectonic models see the Alps chiefly as a collisional orogen, with the Southalpine retrobelt developed only as a post‐collisional feature. New structural and geochronological data show, instead, that the continental margin of Africa‐Adria was being structured as a doubly vergent orogen during ...

A Paradigm Shift: North China Craton's North Margin Orogen Is the Collisional Suture With the Columbia Supercontinent

Geochemistry, Geophysics, Geosystems, 2023
In a new study, Wu, Wang, Zhou, Zhao, Haproff, et al. (2022, https://doi.org/10.1029/2022GC010662) present a comprehensive study of the North Margin Orogen of the North China Craton (NCC), showing that older accreted rocks in this belt preserve a record ...

The seismic attenuation signature of collisional orogens and sedimentary basins within the Carpathian Orogen

Global and Planetary Change, 2023
Sedimentary basins in collisional settings result from interactions within and between lithospheric plates and sublithospheric mantle. Imaging their structure brings fundamental constraints to both the extraction of hy-drocarbon or geothermal resources and seismic hazard analyses, especially in seismogenic areas affected by fluid percolation.

Spatiotemporal Characteristics of Tectonic Tremors in the Collisional Orogen of Taiwan

Geophysical Research Letters
Taiwan offers a distinctive tectonic setting as a collisional orogen, ideal for studying tectonic tremors and the slow deformation process in the mountain‐building process.

Heterogeneous Mantle Metasomatism Controlled by Continental Subduction: Evidence From Post‐Collisional Mafic Rocks in the North Qaidam Orogen

Geochemistry, Geophysics, Geosystems
Post‐collisional mafic rocks not only record geodynamic processes at the end of the orogenic cycle but also retain various clues regarding preceding interactions between subducted slabs and mantle wedges.

The fate of calcareous pelites in collisional orogens [PDF]

Journal of Metamorphic Geology, 2020
AbstractAlthough calcareous pelites are important constituents of sediments involved in orogenic processes, their prograde metamorphism is significantly less studied than that of pure pelites with negligible amounts of modal calcite. This paper presents mineral equilibria modelling in the system MnO–Na2O–K2O–CaO–FeO–MgO–Al2O3–SiO2–TiO2–H2O–CO2, with ...
