Petrological and structural analysis of the Haukivesi area between Varkaus and Savonlinna, Finland [PDF]

Bulletin of the Geological Society of Finland, 1971
The Haukivesi area is part of a Precambrian orogenic belt. Its supracrustal rocks can be regarded as having been deposited in a geosynclinal system consisting of an eugeosynclinal basin in the northern and central Haukivesi area and a miogeosynclinal ...

Metamorphic core complexes vs. synkinematic plutons in continental extension setting: insights from key structures (Shandong Province, eastern China) [PDF]

, 2011
International audienceContinental extension is an important geodynamical process mostly diagnostic of a peculiar behaviour of the crust accommodated by geological structures that highlight these specific conditions in the crust. Though a Metamorphic Core

Fluid or Melt? Distinguishing Syn‐Deformational Interaction Pathways

Journal of Metamorphic Geology, Volume 43, Issue 8, Page 810-838, October 2025.
ABSTRACT Understanding whether deformation occurred in the presence of aqueous fluid or silicate melt is crucial for interpreting ductile shear zones, impacting their thermal and geochemical evolution, and having rheological consequences. To identify the syn‐deformational fluid type, we investigate contrasting shear zones active during the Alice ...

Deformation partitioning in the mid- to deep sheared crust of the Variscan Fautea-Favone metamorphic complex (southern Corsica, France)

Journal of Maps
The Variscan basement in Corsica (France) is exposed as scattered metamorphic complexes preserved in the late Permian batholith in the south-western sector of the island.

Polyorogenic evolution of the Paleoproterozoic Trans-North China Belt, new insights from the in Lüliangshan-Hengshan-Wutaishan and Fuping massifs

, 2007
http://www.episodes.org/backissues/302/abstract2.htmInternational audienceThe Trans-North China Belt (TNCB) is a Paleoproterozoic collisional orogen (ca. 1.9-1.8 Ga) responsible for the amalgamation of the North China Craton.

Long‐Lasting Plutonism During Orogenic Cycles: Incremental Emplacement of the Variscan Bassiès Pluton (Central Pyrenees, France)

Terra Nova, Volume 37, Issue 5, Page 316-323, October 2025.
ABSTRACT Laser ablation U–Pb single zircon geochronology was applied to four peraluminous granite and granodiorite samples from the Bassiès pluton in the Central Pyrenees (France) yielding a wide range of concordant ages from early Carboniferous (Tournaisian, 351 Ma) to early Permian (Artinskian, 285 Ma).

Subduction‐Driven Reworking of Craton and Accretionary Orogen: Evidence From Integrated Geophysical Imaging in Western North China Craton

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Observations and interpreted mechanisms for the reworking of Precambrian cratons and accretionary orogens have significant relevance in understanding the history and evolution of continental lithosphere. Here we investigate the Precambrian basement and lithospheric architecture of the western North China craton (NCC) through the integration of

Prograde zircon growth in migmatites

Journal of Metamorphic Geology, 2023
AbstractEmpirical studies of zircon in migmatites document features compatible with growth during heating at suprasolidus conditions. However, numerical modelling of zircon behaviour suggests that suprasolidus zircon is expected to grow only during cooling and melt crystallization.
