Thermokinematic evolution of the Annapurna-Dhaulagiri Himalaya, central Nepal: The composite orogenic system [PDF]
, 2016 The Himalayan orogen represents a ‘‘Composite Orogenic System’’ in which channel flow, wedge extrusion, and thrust stacking operate in separate ‘‘Orogenic Domains’’ with distinct rheologies and crustal positions.

Interpreting Europium Anomalies in Zircon: The Importance of Source Redox
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract The sources of granitoids are variably oxidized due to the diversity of environments in which they form. This environmental and consequent chemical variability leads to differences in mineral assemblages, proportions, and compositions of ferric and ferrous iron‐bearing phases in these sources and in the resultant granitoids. Accessory minerals

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.Abstract Whereas the ability to acquire petrochronological data from detrital minerals has exploded, development of tools to analyze and interpret the multivariate data sets has not kept pace. Herein, we present a case study, which applies the recently developed non‐negative Tucker‐1 decomposition (NNT1) method to a multivariate detrital zircon data ...

Recent advances in petrochronology: from dates to ages and rates of deep orogenic processes
Comptes Rendus. GéoscienceIn order to decipher the prevalent processes active at depth in orogenic systems, their time sequence and their rates have to be assessed. This is essentially done via absolute dating of accessory and rock-forming metamorphic minerals. The interpretation

Journal of Metamorphic Geology, Volume 43, Issue 5, Page 467-495, June 2025.ABSTRACT The pressure–temperature–time (P–T–t) evolution of a metapelitic ultrahigh‐temperature (UHT) granulite from Rundvågshetta (Lützow–Holm Complex, East Antarctica) and chemical evolution of partial melt during the prograde metamorphism up to UHT metamorphism are studied in detail.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract High heat fluxes occurring in rift settings are expected to generate partially melted low‐pressure–high‐temperature granulites (LP–HTG). Therefore, studying these rocks can offer valuable insights into crustal reworking during extension. However, our interpretations are limited by the rarity of LP–HTG in the metamorphic record.
