Paleogeographic significance of Upper Triassic basinal succession of the Tamar Valley, northern Julian Alps (Slovenia)

open access: yesGeologica Carpathica, 2015
The Julian Alps (western Slovenia) structurally belong to the eastern Southern Alps. The Upper Triassic succession mostly consists of shallow water platform carbonates of the Dolomia Principale-Dachstein Limestone system and a deep water succession of ...

Probabilistic Identification of Debris‐Flow Pathways in Mountain Fans Within a Stochastic Framework

open access: yesJournal of Geophysical Research: Earth Surface, Volume 129, Issue 12, December 2024.
Abstract Debris flows are solid‐liquid mixtures originating in the upper part of mountain basins and routing downstream along incised channels. When the channel incises an open fan, the debris flow leaves the active channel and propagates downstream along a new pathway. This phenomenon is called an avulsion.

U‐Pb carbonate dating reveals long‐lived activity of proximal margin extensional faults during the Alpine Tethys rifting

open access: yesTerra Nova, Volume 36, Issue 5, Page 347-357, October 2024.
Abstract Syn‐rift extensional faults play a significant role during the early stage of rifting. Constraining the age of faulting, and how and when deformation shifts from the proximal to the distal margin areas, is crucial for the reconstruction of the rifting process. Previous assessments of the structural and temporal evolution of rift‐related faults

THE LATE TRIASSIC-HETTANGIAN BIVALVES TURNOVER IN LOMBARDY (SOUTHERN ALPS)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
One of the major mass extinctions of the Phanerozoic took place at the Rhaetian-Hettangian boundary. According to some researchers, it might have been preceded by a minor event at the end of the Carnian. The faunal association present in the Late Trixsic

Finite element analysis of early deformations of carbonate platforms driven by differential compaction of basinal unit

open access: yesBasin Research, Volume 36, Issue 5, September–October 2024.
We investigate the relation between the differential compaction of the basinal unit and the early deformation of a growing carbonate platform using a 2D finite element model (a). We compare the results with two Triassic carbonate platforms in the Italian Dolomites: Lastoni di Formin and Nuvolau Mts (b).

A Middle Triassic Cassian‐type fauna (Pelsa‐Vazzoler Lagerstätte) and the adaptive radiation of the Modern evolutionary fauna

open access: yesPapers in Palaeontology, Volume 10, Issue 4, July/August 2024.
Abstract We describe a high‐diversity silicified assemblage of marine molluscs (Pelsa‐Vazzoler Lagerstätte) from the upper Ladinian of the Agordo Dolomites (northeastern Italy). New data on the Triassic rebound, after the end‐Permian mass extinction, constrain it to an interval of relatively stable climatic conditions.

Co‐precipitation of primary dolomite and Mg‐rich clays in Deep Springs Lake, California

open access: yesSedimentology, Volume 71, Issue 4, Page 1363-1383, June 2024.
ABSTRACT In contrast to the prevalence of dolomite [CaMg(CO3)2] in the geological record, there are few instances of recent formation. This discrepancy occurs despite supersaturation with respect to dolomite in many modern marine and lacustrine environments.

BIOSTRATIGRAFIA E PALEOGEOGRAFIA DELL'AREA SUD-OCCIDENTALE DELL'ANTICLINALE M. MIA - M. MATAJUR (PREALPI GIULIE)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2020
he aim of this work is the stratigraphic revision of the sequences outcropping on the southwestern side of the M. Mia — M. Matajur anticline. This area, until now, was poorly studied from a geological point of view.

Soft‐sediment deformation structures and Neptunian dykes across a carbonate system: Evidence for an earthquake‐related origin (Norian, Dolomia Principale, Southern Alps, Italy)

open access: yesSedimentology, Volume 71, Issue 3, Page 827-849, April 2024.
Abstract Identification of the processes producing soft‐sediment deformation structures, common in siliciclastic deposits and less abundant in carbonate successions, is complex, because different processes may produce similar structures. Thus, interpreting the origin of these structures may be challenging: it requires both a detailed sedimentological ...
