Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Evidence for Limited Atmospheric CO2 Rise at the Miocene Climatic Optimum

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a relatively warm period with atmospheric CO2 averaging ∼500 μatm but CO2 change across its onset is poorly documented. We present a record of algal 13C‐fractionation covering the Early to Middle Miocene (∼18.5–15 Ma), with a gap at the MCO onset, from Ocean Drilling Program Site 959 in the ...

AGES OF THE ONSET OF MARLY SEDIMENTATION AND OF THE BLACK SHALES IN THE TUSCAN BASIN (NORTHERN APENNINES, ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2008
In this paper is for the first time dated the inception of the Lower Jurassic marly sedimentation and the lower Toarcian black shales in the Tuscan Nappe, based on semiquantitative analysis of the calcareous nannofossils recovered from the Calcare ...

Late Pliocene calcareous nannofossil paleobiogeography of the Pacific Ocean: evidence for glaciation at 2.75 Ma

Revista Mexicana de Ciencias Geológicas, 2018
Calcareous nannofossil assemblages from land sections of the Japanese Islands and DSDP Holes in the equatorial to high latitude regions of the Pacific Ocean were analyzed in an effort to reconstruct their late Pliocene paleobiogeography.

Calcareous nannofossil bioevents at the Paleocene/Eocene boundary in Kharga Oasis, Western Desert of Egypt

Geologia Croatica, 2017
Two upper Palaeocene – lower Eocene stratigraphic sequences at the Kharga Oasis (Umm El Ghanayim and Naqb Assiut sections) were studied biostratigraphically on the basis of their calcareous nannofossil content.

HIGH RESOLUTION CALCAREOUS PLANKTON BIOSTRATIGRAPHY OF THE SERRAVALLIAN SUCCESSION OF THE TREMITI ISLANDS (ADRIATIC SEA, ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2002
The planktonic foraminifer and calcareous nannofossil content of two Middle Miocene sections of the Tremiti Islands (Southern Adriatic Sea) have been studied. The two sections are composed of marly limestones rich in calcareous plankton which show cyclic
