Solid Earth Carbon Degassing and Sequestration Since 1 Billion Years Ago

open access: yesGeochemistry, Geophysics, Geosystems
Solid Earth CO2 outgassing, driven by plate tectonic processes, is a key driver of carbon cycle models. However, the magnitudes and variations in outgassing are poorly constrained in deep‐time.

EARTHQUAKE SWARMS AS EVIDENCE OF VOLCANO-TECTONIC PROCESSES OF THE SLOWEST SPREADING GAKKEL RIDGE IN THE ARCTIC

open access: yesГеодинамика и тектонофизика
Based on the data from the Arctic regional seismic stations, the article presents the results of studying the swarm seismicity of the Gakkel Mid-Ocean Ridge, located in the Arctic Ocean.

Miocene deep-water agglutinated foraminifera from the Lomonosov Ridge and the opening of the Fram Strait [PDF]

open access: yes, 2009
Deep-water agglutinated Foraminifera (DWAF) were recovered from Miocene to Pliocene sediments in 103 samples from IODP Hole M0002A on the Lomonosov Ridge.

Carbonate sedimentology: An evolved discipline

open access: yesThe 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.

MORPHOSTRUCTURE OF ATLANTIC’S BOTTOM AND MEDIUM ATLANTIC RIDGE

open access: yesГеологія і корисні копалини Світового океану, 2019
The purpose of the study is to characterize the morphostructure and geology of Atlantic's bottom and the Mid Atlantic Ridge using generalized and new data. The basis is the bathymetric map of the Atlantic 1971, according to research data of the Institute

Polygonal tepee structures of Arabia

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

The middle Pleistocene extinction of bathyal benthic foraminifera in the South Atlantic (ODP sites 1082 and 1088) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Earth Science at Massey University [PDF]

open access: yes, 2005
The youngest major turnover in deep-sea benthic foraminifera (termed the Stilostomella extinction) is documented in two ODP sites in the South Atlantic Ocean.

Hydrothermal dolomitisation of a deep‐water bioherm isolated in a non‐dolomitised intraplatform basin within the Norian Dolomia Principale (Southern Alps, northern Italy)

open access: yesThe 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
