Iberian Ordovician and its International Correlation

, 2015
Theregionalchronostratigraphy of the British Ordovician, established mainly for shelly facies, is hard to correlate in the Iberian Peninsula, especially after the separation and drift of Avalonia from Gondwana by the early Middle Ordovician.

Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

Arabian Archaeology and Epigraphy, Volume 37, Issue 1, Page 182-206, November 2026.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.
