Crustal influx, indentation, ductile thinning and gravity redistribution in a continental wedge: Building a Moldanubian mantled gneiss dome with underthrust Saxothuringian material (European Variscan belt) [PDF]

open access: yesTectonics, 2012
27 p.International audience[1] The contribution of lateral forces, vertical load, gravity redistribution and erosion to the origin of mantled gneiss domes in internal zones of orogens remains debated.

The giant Shakhdara migmatitic gneiss dome, Pamir, India‐Asia collision zone: 2. Timing of dome formation

open access: yesTectonics, 2013
Cenozoic gneiss domes—exposing middle‐lower crustal rocks—cover ~30% of the surface exposure of the Pamir, western India‐Asia collision zone; they allow an unparalleled view into the deep crust of the Asian plate. We use titanite, monazite, and zircon U/Th‐Pb, mica Rb‐Sr and 40Ar/39Ar, zircon and apatite fission track, and zircon (U‐Th)/He ages to ...

Evolution of North Himalayan gneiss domes: structural and metamorphic studies in Mabja Dome, southern Tibet [PDF]

open access: yesJournal of Structural Geology, 2004
Field, structural, and metamorphic petrology investigations of Mabja gneiss dome, southern Tibet, suggest that contractional, extensional, and diapiric processes contributed to the structural evolution and formation of the domal geometry. The dome is cored by migmatites overlain by sillimanite-zone metasedimentary rocks and orthogneiss; metamorphic ...

Time-space distribution of silicic plutonism in a gneiss dome of the Iberian Variscan Belt: The Évora Massif (Ossa-Morena Zone, Portugal) [PDF]

open access: yesTectonophysics, 2018
In the Iberian Variscan Belt, polyphasic deformation has been recognized as comprising an early phase of crustal thickening, followed by an intermediate phase of crustal extension and doming, and a later phase of shortening.

Late Cenozoic cooling and evolution history of the Kangmar dome in southern Tibet: Insights from inverse thermal modeling

open access: yesFrontiers in Earth Science, 2023
The North Himalayan Gneiss Domes, which are essential parts of the Cenozoic extensional structures in Southern Tibet, record the thermal and tectonic processes that occurred after the India-Asian collision and are thought to be effective structures ...

S-wave velocity characteristics and mineralization of the southern tibet detachment system-yalaxiangbo dome

open access: yesFrontiers in Earth Science, 2023
A series of extensional structures, including the southern Tibet detachment system (STDS), the north-south trending rifts (NSTR), and the northern Himalayan gneiss dome (NHGD), developed from the collision and compression between the Indian and Eurasian ...

Exhumation history of eastern Ladakh revealed by Ar-40/Ar-39 and fission-track ages: the Indus River-Tso Morari transect, NW Himalaya [PDF]

open access: yes, 2003
Fission-track and Ar-40/Ar-39 ages place time constraints on the exhumation of the North Himalayan nappe stack, the Indus Suture Zone and Molasse, and the Transhimalayan Batholith in eastern Ladakh (NW India).

Kinematics, deformation partitioning and late Variscan magmatism in the Agly massif, Eastern Pyrenees, France

open access: yesBSGF - Earth Sciences Bulletin, 2020
In order to constrain the finite deformation pattern of the Variscan basement of the Agly massif, a detailed structural analysis over the whole Agly massif was performed.

Continental breakup and UHP rock exhumation in action: GPS results from the Woodlark Rift, Papua New Guinea [PDF]

open access: yes, 2015
We show results from a network of campaign Global Positioning System (GPS) sites in the Woodlark Rift, southeastern Papua New Guinea, in a transition from seafloor spreading to continental rifting. GPS velocities indicate anticlockwise rotation (at 2–2.7°

Structural Evolution of Extended Continental Crust Deciphered From the Cretaceous Batholith in SE China, a Kinmen Island Perspective

open access: yesFrontiers in Earth Science, 2020
The continental crust of southeast Asia underwent from thickening, thinning to almost rifting during the Mesozoic era as the active continental margin transformed into a passive one.
