How life affects mineral formation: A reappraisal of concepts and terminology
The Depositional Record, Volume 12, Issue 4, September 2026.We present a moderately revised terminology of concepts how life may influence mineral formation. This framework would be more consistent and universally applicable. Abstract Numerous biological factors have been proposed to influence the formation of minerals under Earth‐surface conditions, but the underlying concepts are often confused due to ...

Taxonomy and biostratigraphy of new and emended species of Cenozoic deep-water agglutinated foraminifera from the Labrador and North Seas [PDF]
, 1989 Deep marine, fine grained sedimentary strata of Maastrichtian through Miocene age in the Labrador and North Sea sedimentary basins are rich in agglutinated benthic foraminifera.

AMS 14C dating of Holocene estuarine deposits: consequences of high energy and reworked foraminifera
, 2000 Benthic foraminiferal species were used to AMS date Holocene sediments adjacent to trangressive overlap boundaries (TOB) in two high-energy estuaries in northern Spain.

Geologica Acta, 2009 The Galala Mountains in Egypt provide an excellent platform-basin transect with deposits spanning the Paleocene/ Eocene (P/E) boundary. These interfingering deposits enable a recalibration between platform and open marine biostratigraphic schemes.

The Depositional Record, Volume 12, Issue 4, September 2026.This study compares primary dolomite precipitation in modern and ancient environments, varying from coastal to transitional to continental saline environments. The microbially mediated dolomites are characterised by high Sr concentrations. Here, various geochemical proxies are studied and compared to previous findings.

Miocene deep-water agglutinated Foraminifera from ODP Hole 909c: Implications for the paleoceanography of the Fram Strait Area, Greenland Sea [PDF]
, 2005 Deep-water agglutinated Foraminifera (DWAF) are investigated from Miocene sediments recovered from ODP Hole 909C in the Fram Strait, Norwegian-Green land Sea. We studied 125 samples from Cores 909C-50R to -103R. and recovered over 60 species of DWAF. The

Pyrosome fecal pellet production: Implications for grazing and carbon export
Limnology and Oceanography, Volume 71, Issue 9, September 2026.Abstract This study quantifies the fecal pellet production and pellet sinking rates of the pyrosome Pyrosoma atlanticum in the Southern California Current across a range of conditions, from the productive nearshore to the oligotrophic offshore. Fecal pellet production rates averaged 1310 ± 76 pellets h−1, resulting in the production of up to 390,380 ...
