Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane [PDF]
, 2015 The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand collision process is a Middle?

A Paleotectonic Atlas of the African Plate: Permian to Recent
Journal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Wilson study cycles: Research relative to ocean geodynamic cycles [PDF]
The effects of conversion of Atlantic (rifted) margins to convergent plate boundaries; oceanic plateaus at subduction zones; continental collision and tectonic escape; southern Africa rifts; and global hot spot distribution on long term development of ...

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

Size and Exhumation Rate of Ultrahigh-Pressure Terranes Linked to Orogenic Stage [PDF]
, 2012 A growing set of data indicates a stark contrast between the evolution of two types of ultrahigh-pressure (UHP) terranes: large terranes that evolved slowly (over 10–30 Myr), and small terranes that formed and were exhumed on timescales of \u3c 10 Myr ...

Fluid-induced high-temperature metasomatism at Rundvågshetta in the Lützow-Holm Complex, East Antarctica: Implications for the role of brine during granulite formation [PDF]
, 2018 We report new petrological, phase equilibria modeling, and fluid inclusion data for pelitic and mafic granulites from Rundvågshetta in the highest-grade region of the Neoproterozoic Lützow-Holm Complex (LHC), East Antarctica, and provide unequivocal ...
