Occurrence and distribution of barite in the permo-triassic siksikpuk formation along the Brooks Range haul road [PDF]
, 1980 Barite commonly occurs in Permian to Triassic age rocks along the north flank of the Brooks Range. The Siksikpuk Formation (Wolfcampian to lowest Guadalupian age) is noted for its barite and is well exposed in the vicinity of Galbraith Lake along the ...

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.

Carbonate sedimentology: An evolved discipline
The Depositional Record, Volume 12, Issue 1, February 2026.Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

The Depositional Record, Volume 12, Issue 1, February 2026.This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

The Depositional Record, Volume 12, Issue 1, February 2026.We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation

Frontiers in Earth Science, 2015 The Cingoli arcuate anticline is part of the Apennines fold-thrust belt in Italy. The anticline involves sedimentary carbonate strata generally affected by syn-thrusting contractional structures such as bed-normal pressure solution seams, folds, and ...

Hydrological Processes, Volume 40, Issue 2, February 2026.Spatial variability in surface water activation and persistence decreased with ongoing drought. The importance of landscape attributes in explaining surface water presence decreased throughout the drought. Flow activation events after several years of drought were more closely associated with precipitation event characteristics than antecedent storage ...
