Facies-succession and architecture of the third-order sequences and their stratigraphic framework of the Devonian in Yunnan-Guizhou-Guangxi area, South China

open access: yesJournal of Palaeogeography, 2013
The Caledonian orogeny at the end of the Silurian resulted in great changes in the palaeogeography in the Yunnan-Guizhou-Guangxi area of South China; the continental area of the Early Paleozoic evolved into the extensive Dian-Qian-Gui Sea in the Late ...

Phylogenetic revision of Leptodesma (Leiopteria) (Devonian: Bivalvia) [PDF]

open access: yes, 2004
The phylogenetic relationships of Middle and Late Devonian species of the subgenus Leptodesma (Leiopteria) Hall 1883 are examined cladistically and a taxonomic revision of the subgenus is proposed.

Constraints for post-orogenic extension of the northern margin of the Qaidam Basin from the Late Silurian–Late Devonian igneous rocks in the Gahai–Nanshan area

open access: yesDizhi lixue xuebao
Objective  The northern margin tectonic zone of the Qaidam Basin underwent a transition from oceanic subduction to continental subduction during the Early Paleozoic, resulting in the formation of the ultrahigh-pressure metamorphic zone known as the ...

Stratigraphic distribution and systematic composition of the Middle-Upper Devonian placoderms (anti-archs) from Central Kazakhstan

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2016
The stratigraphie distribution and systematic composition of the Middle-Upper Devonian remains of antiarchs from the sediments of Central Kazakhstan are analyzed. Central Kazakhstan ichthyofauna contains mainly endemic taxons of antiarchs.

Late Devonian and Carboniferous acritarch stratigraphy and paleogeography [PDF]

open access: yes, 1986
Detailed analysis of literature on late Devonian and Carboniferous acritarchs learns that, up to now, late Devonian acritarch zonation has been proposed only for Algeria, U.S.A. and Belgium.

Transitional changes in arborescent lignophytes at the Devonian–Carboniferous boundary

open access: yes, 2016
It is usually considered that after the extinction of the Devonian tree Archaeopteris, no new arborescent lignophytes were established before the late Tournaisian.

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

open access: yesNew 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 ...
