Late Devonian mineralisation, north Queensland: volcanic sources in sediments of the Palaeopacific Rim

open access: yes, 1987
A Devonian metallogenic province is extended northwards from central Queensland to the Burdekin Basin in the Charters Towers Gold and Mineral Field. Devonian sediments of the Burdekin Basin are intruded by mineralised quartz felspar porphyry which occurs

Structural interpretation of the Yunyakha area based on the sedimentation model of the Bolshaya nadota isolated carbonate platform [PDF]

open access: yesНефтегазовая геология: Теория и практика
The 1-Yunyakha borehole is located in the Polar Urals, where the Elets and Lemva structural zones are in contact. Sedimentological analysis can be performed on paragenetic associations by examining core samples from the Late Devonian - Early ...

Late Palaeozoic Corals from the Himalayas [PDF]

open access: yes, 1989
Permian corals, representing 3 typical Tethyan genera (Protomichelinia, Iranophyllum and Ipciphyllum) are described from the Shyok Melange, near Shigar, Baltislan.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, Volume 55, Issue 4, Page 1208-1227, October 2026.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

open access: yesNew Phytologist, Volume 252, Issue 1, Page 54-68, October 2026.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Recognition of fossil keratose sponges in carbonates using petrographic and machine‐learning classification

open access: yesSedimentology, Volume 73, Issue 6, Page 2246-2280, October 2026.
ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

open access: yesSedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the
