Transformaciones edaficas y diageneticas de los depositos aluviales distales del mioceno de la cuenca de Madrid, area de Paracuellos de Jarama

Estudios Geologicos, 2003
Los depósitos distales de los abanicos aluviales arcósicos y también los carbonatos palustres del área de Paracuellos de Jarama presentan rasgos muy específicos debidos a los procesos edáficos y diagenéticos que han sufrido. Los procesos que han afectado

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

BIRD-LIKE HEAD ON A CHAMELEON BODY: NEW SPECIMENS OF THE ENIGMATIC DIAPSID REPTILE MEGALANCOSAURUS FROM THE LATE TRIASSIC OF NORTHERN ITALY

Rivista Italiana di Paleontologia e Stratigrafia, 2000
Two new Megalancosaurus specimens collected from the Norian (Late Triassic) Calcare di Zorzino (Zorzino Limestone) Formation (Bergamo, Lombardy, Northern Italy), and from the coeval Dolomia di Forni (Forni Dolostone) Formation (Udine, Friuli, North ...

Rainfall‐Runoff Modeling in Rocky Headwater Catchments for the Prediction of Debris Flow Occurrence

Water Resources Research, Volume 61, Issue 1, January 2025.
Abstract In the Dolomites, steep rocky cliffs are marked by numerous narrow gullies. When high‐intensity short‐duration precipitation occurs, these gullies concentrate and direct surface runoff to the screes at the foot of rock cliffs. Surface runoff mixes with loose sediments, creating a solid‐liquid surge that, as it moves downhill, increases its ...

Contact Metamorphism of Pelitic Rocks Constrains the Depth of Emplacement of the Re di Castello Intrusion (Adamello Batholith, Italy)

Journal of Metamorphic Geology, Volume 43, Issue 1, Page 47-69, January 2025.
ABSTRACT Re di Castello is the southernmost unit of the composite Adamello batholith (central Alps, Italy). It was emplaced between 43 and 40 Ma, yet its depth of emplacement is not well constrained. We have studied the contact metamorphism of pelitic country rocks in two localities: the upper Caffaro Valley and the Borzago Valley in the southern and ...

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

Geologica 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

Journal 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

Terra 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

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

Basin 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).

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

Rivista 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.
