Tectonics, Volume 45, Issue 1, January 2026.Abstract Recent observations and drilling campaigns have challenged the typical models for rifted margins by providing evidence for the existence of intermediate cases between the magmatic and amagmatic end‐members. In this contribution, we document the evolution of the Central Campos rifted margin, located in southeast Brazil, based on a combined ...

Groundwater, Volume 64, Issue 1, Page 9-20, January/February 2026.Abstract We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.

Discriminating cool-water from warm-water carbonates and their diagenetic environments using element geochemistry: the Oligocene Tikorangi Formation (Taranaki Basin) and the dolomite effect [PDF]
, 2004 Fields portrayed within bivariate element plots have been used to distinguish between carbonates formed in warm- (tropical) water and cool- (temperate) water depositional settings.

Resource Geology, Volume 76, Issue 1, January‐December 2026.Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western

Conellae, enigmatic structures on cephalopod shells—shapes, distribution, and formation [PDF]
, 2019 Conellae, enigmatic cone-shaped structures which can be found on the surface of internal moulds of cephalopod shells (predominantly of ammonoids), are regarded herein as the product of remote (biologically induced) biomineralization formed in closed-off ...

Some record it hot: Clumped isotope temperatures from Middle Jurassic molluscan aragonite
Sedimentology, Volume 73, Issue 1, Page 248-266, January 2026.ABSTRACT Clumped isotope (Δ47) data from the shell aragonite of Praemytilus strathairdensis, a non‐marine Middle Jurassic mytilid from the Inner Hebrides of Scotland, presents a rare geological context for better understanding the effects of diagenesis on Δ47 in skeletal aragonite. Nineteen P. strathairdensis shells gave Δ47 temperatures between 23 ± 5°
