The crust in the pamir: Insights from receiver functions [PDF]

, 2019
The Cenozoic convergence between India and Asia has created Earth's thickest crust in the Pamir‐Tibet Plateau by extreme crustal shortening. Here we study the crustal structure of the Pamir and western Tian Shan, the adjacent margins of the Tajik, Tarim,

Rb-Sr and in situ 40Ar/39Ar dating of exhumation-related shearing and fluid-induced recrystallization in the Sesia zone (Western Alps, Italy) [PDF]

, 2018
The Sesia zone in the Italian Western Alps is a piece of continental crust that has been subducted to eclogite-facies conditions and records a complex metamorphic history.

Origin and evolution of the Variscan Léon eclogites: insights from zircon and garnet petrochronology [PDF]

European Journal of Mineralogy
Eclogites record the deep burial and exhumation of crustal terranes, which are key tectonic markers in the evolution of orogenic belts. Unraveling the evolution of eclogites and eclogite-bearing terranes may nevertheless be challenging, especially in old

Geochronological challenges posed by continuously developing tectonometamorphic systems: insights from Rb–Sr mica ages from the Cycladic Blueschist Belt, Syros (Greece). [PDF]

, 2016
Is metamorphism and its causative tectonics best viewed as a series of punctuated events or as a continuum? This question is addressed through examination of the timing of exhumation of the Cycladic Blueschist Belt (CBB).

Developing an inverted Barrovian sequence; insights from monazite petrochronology [PDF]

Earth and Planetary Science Letters, 2014
AbstractIn the Himalayan region of Sikkim, the well-developed inverted metamorphic sequence of the Main Central Thrust (MCT) zone is folded, thus exposing several transects through the structure that reached similar metamorphic grades at different times.

Paleoproterozoic Reworking of Archean Crust and Extreme Back‐Arc Metamorphism in the Enigmatic Southern Trans‐Hudson Orogen

Geophysical Research Letters
The crustal evolution of the southernmost ∼2000–1800 Ma Trans‐Hudson orogen (THO) is enigmatic due to burial by Phanerozoic sediments. We provide new insights through petrochronologic analysis of a paragneiss drill core sample.

Indentation of the Pamirs with respect to the northern margin of Tibet: constraints from the Tarim basin sedimentary record [PDF]

, 2016
The Pamirs represent the indented westward continuation of the northern margin of the Tibetan Plateau, dividing the Tarim and Tajik basins. Their evolution may be a key factor influencing aridification of the Asian interior, yet the tectonics of the ...

Rapid Transition From High‐Pressure Metamorphism to Exhumation Driven by Orogen‐Parallel Extensional Shearing (Adula Unit, Eastern Central Alps)

Tectonics, Volume 45, Issue 2, February 2026.
Abstract In the Central Alps, the Adula unit exposes high‐ and ultra‐high‐pressure (HP‐UHP) metamorphic rocks, providing key insights into the subduction and exhumation dynamics of the former distal European margin. We investigate the San Bernardino Shear Zone (SBSZ), a top‐to‐the‐east extensional shear zone developed within orthogneiss and paragneiss ...
