LIVELLI CALCAREI CLASTICI DEL MIOCENE SUPERIORE E PLIOCENE NEL SOTTOSUOLO MOLISANO-PUGLIESE

Rivista Italiana di Paleontologia e Stratigrafia, 2020
The Molise and Apulia subsurface exploration has found clastic calcareous layers at the top of the Mesozoic—Miocene carbonate sequence and within the Middle Pliocene turbidites.

Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Turbidites in the Damara Orogen

, 1983
Three pre-orogenic turbidite sequences are developed in the north-east-trending branch of the Damara Orogen. They are all related to rift structures of the early Damaran “graben stage”.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

FACIES AND ARCHITECTURE OF A SAND-RICH TURBIDITE SYSTEM IN AN EVOLVING COLLISIONAL-TRENCH BASIN: A CASE HISTORY FROM THE UPPER CRETACEOUS-PALAEOCENE GOTTERO SYSTEM (NW APENNINES)

Rivista Italiana di Paleontologia e Stratigrafia, 2019
This study documents the main depositional elements of a dynamically-controlled sand-rich deep-water turbidite system (Upper Cretaceous–Palaeocene Gottero system, north-west Italy).

Continental Growth and Recycling in Convergent Orogens with Large Turbidite Fans on Oceanic Crust

Geosciences, 2013
Convergent plate margins where large turbidite fans with slivers of oceanic basement are accreted to continents represent important sites of continental crustal growth and recycling.

Overview and Reinstatement of Some Geophysical Interpretations in the Eastern Sava Depression

Rudarsko-geološko-naftni Zbornik, 2015
The eastern part of Sava Depression is bounded on the south with the Sava River and on the north with Psunj Mountain, Požeška and Dilj Hills. In this part thicker Neogene-Quaternary sediments than in the western part were found, and there is almost never

The origin of planar lamination in fine‐grained sediment deposited by subaqueous sediment gravity flows

The Depositional Record
Planar lamination is a ubiquitous component of modern and ancient fine‐grained sediments deposited by subaqueous sediment gravity flows. These sediments commonly exhibit alternating sub‐millimetre‐thick, sharply bounded silt‐rich and clay‐rich layers ...
