Record of Tethyan ocean closure and Indosinian collision along the Ailaoshan suture zone (SW China) [PDF]

, 2015
Zircon U–Pb and Lu–Hf isotopic data along with whole-rock elemental and Sr–Nd isotopic analytical results for the Xin'anzhai and Tongtiange granitic plutons in the Ailaoshan suture zone record the transition from subduction to collision associated with ...

Two Cycles of Devonian–Triassic Extension and Compression in the Altai Accretionary Wedge: Insights From Tsogt Core Complex

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...

A Dual‐Geochronologic and Thermochronologic Detrital Approach to Identify the Focus of Erosion in the Kosi Basin, Nepal

Tectonics, Volume 44, Issue 12, December 2025.
Abstract The Kosi River watershed captures the major lithotectonic units, structures, and characteristic climatic conditions found along the Himalaya. Therefore, this setting provides a useful location to investigate the respective influences of tectonics and climate in eroding bedrock and driving landscape evolution.

A newly identified cryogenian (ca. 806 ma) basement tonalite gneiss from the Eastern Karakoram, NW India: Constraints from geochemistry and zircon U-Pb geochronology

Frontiers in Earth Science, 2022
The Karakoram Terrane (KT) represents the southern margin of the Eurasian Plate, mainly consisting of Late Jurassic-Early Cretaceous subduction-related granites and post-collisional Miocene leucogranites, which intrude the Late Neo-Proterozoic basement ...

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Late Svecofennian leucogranites of southern Finland : Chronicles of an orogenic collapse [PDF]

, 2011
Leucogranite magmatism occurred in southern Finland during the later stages of the Paleoproterozoic Svecofennian orogeny. The leucogranites are considered to have formed from pre-existing crustal rocks that have undergone anatexis in the extensional ...

Petrogenesis of synorogenic high-temperature leucogranites (Damara orogen, Namibia): Constraints from U–Pb monazite ages and Nd, Sr and Pb isotopes [PDF]

, 2014
Highlights: • Geochemical data from high-T leucogranites imply pure crustal melting. • New U–Pb monazite ages constrain intrusion time close to peak metamorphism. • Updated Sr–Nd–Pb isotope data imply metasedimentary sources.

Radiogenic Heating as the Thermal Driver of Himalayan Crustal Heating During Prolonged Thickening

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The thermal evolution of the crust during continental collision evolves from cold to hot with time, which impacts crustal reworking and differentiation. However, it remains elusive as to the mechanism driving the crust to be hot during the protracted collision.

Himalayan Leucogranites: An Experimental Petrology Perspective

Elements
The High Himalayan leucogranites (HHL) are produced by muscovite breakdown of a metapelitic source, at temperatures below 800 °C, with initial melt water contents of ~5–7 wt.%. The tourmaline-rich HHL variety is colder, possibly a fractionation product of the hotter two-mica HHL.

Transpressional tectonics and Carboniferous magmatism in the Limousin, Massif Central, France: Structural and ⁴⁰Ar/³⁹Ar investigations [PDF]

, 2007
New structural, microstructural, and 40Ar/39 Ar data from the NW Massif Central (France) provide additional constraints on the timing and tectonic setting of late Variscan granite magmatism.
