"Hot and sticky" and "cold and damp" pyroclastic eruptions, and their relationship with topography: valley- and lake-filling ignimbrites, Ardnamurchan, NW Scotland

Volcanica
Pyroclastic density currents are complex mixtures of rock, ash and gas and represent significant hazards at many active volcanoes worldwide. Ignimbrites are the deposits of pyroclastic density currents and can be used to record the eruption dynamics and ...

Note “Paleocene” or “Palaeocene”

Bulletin of the Geological Society of Denmark, 1999
There seems to be some doubt as to which of the spellings “Paleocene” or “Palaeocene” should be used in manuscripts submitted for publication in Europe, while in North America the spelling “Paleocene” is standard. The latter is not surprising, as in North America the prefix paleo- is also used in terms such as Paleozoic, paleomagnetism, etc. In Europe,

First Clarkforkian equivalent Land Mammal Age in the latest Paleocene basal Sparnacian facies of Europe: fauna, flora, paleoenvironment and (bio)stratigraphy.

PLoS ONE, 2014
The Paleocene-Eocene Thermal Maximum (PETM) is correlated with the first occurrences of earliest modern mammals in the Northern Hemisphere. The latest Paleocene Clarkforkian North American Land Mammal Age, that has yielded rodents and carnivorans, is the

Chronostratigraphic terminology at the Paleocene/Eocene boundary

, 2003
Integrated research over the past decade has led to the recognition of a short (150-200 k.y.) interval of Paleogene time within Chron C24r at ~55.5 Ma, formerly termed the late Paleocene Thermal Maximum (LPTM) but more recently the Paleocene-Eocene Thermal Maximum (PETM), that was crucial in the climatic, paleoceanographic, and biotic evolution of our ...

Lower Paleogene Tectonostratigraphy of Balochistan: Evidence for Time-Transgressive Late Paleocene-Early Eocene Uplift

Geosciences, 2013
Analysis of lithofacies, paleoflow directions, and sandstone petrography of upper Paleocene-lower Eocene paralic and continental sediments exposed along the transpressional suture zone of the western margin of the Indian plate indicate that the process ...

Assessing the Duration of the Paleocene‐Eocene Thermal Maximum [PDF]

Geophysical Research Letters
Abstract The Paleocene‐Eocene Thermal Maximum (PETM) was a climate/carbon cycle perturbation recognized in stable carbon isotope (δ 13 C) records with a negative carbon isotope excursion (CIE). The PETM CIE termination has been associated with a δ 13

The first finding of rodingites with a gold-palladium-platinum mineralization within the Sikhote-Alin

Литосфера, 2017
The subject of investigations were rodingites, whose outcrops were recently found inTaukha terrane of the Sikhote-Alin. The contents of the rock-forming oxides in rodingites were determined using the methods of chemical analysis as well as the gravimetry

Assessments of Liquefaction Triggering and Manifestation at Three Case History Sites in Napier Based on 1931 Hawke's Bay, New Zealand, Earthquake

Earthquake Spectra, Volume 42, Issue 3, August 2026.
The 1931 Hawke's Bay earthquake (∼MS 7.8) stands as one of New Zealand's most devastating, causing widespread liquefaction and damage across the city of Napier. However, Napier remains underrepresented in liquefaction hazard studies as compared to other regions in the country.

TAXONOMY AND EVOLUTIONARY RELATIONSHIPS WITHIN THE CALCAREOUS NANNOFOSSIL GENUS ERICSONIA IN THE UPPER PALEOCENE

Rivista Italiana di Paleontologia e Stratigrafia, 2018
Detailed distribution ranges of the genus Ericsonia were obtained in the upper Paleocene interval from two deep-sea sections, ODP Site 1262 (South Eastern Atlantic Ocean) and Site 1215 (Eastern Equatorial Pacific Ocean), and were complemented with ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.
