The Chuquibamba Landslide Western Cordillera, Peru revisited: New Evidence of a Dry Debris Avalanche

open access: yesGeofísica Internacional
Landslides represent a serious mountain hazard to lives and infrastructure, especially when geological factors such as highly fractured rocks, faulting, steep topography, and weathering combine with seismic triggering factors.

New data on depositional environment of Jurua Formation terminal sediments, Solimoes Basin, Brazil

open access: yesGeoresursy, 2019
It has been for the first time established on the core taken from two wells that JR10 reservoir sediments (Upper Jurua, Formation Carboniferous) were deposited in the conditions of deltaic and alluvial coast with semiarid climate and in marine ...

A man with leonine facies [PDF]

open access: yesBMJ Case Reports, 2012
A 42-year-old man presented with gradually progressive thickening of his scalp, face and extremities. He also complained of hyperhidrosis of palms and sole. On examination, he had coarse ‘leonine like’ facies, with thickened folded skin of face, eyelids and scalp with mechanical partial ptosis (figure 1).

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Deposition, diagenesis, and reservoir development of the Cretaceous Lidam formation, SE Sirt Basin, Libya. [PDF]

open access: yes, 2007
This study concentrates on the deposition, diagenesis and reservoir characteristics of the Upper Cretaceous (Cenomanian) Lidam Formation. Core, petrography and geochemical data were studied from five wells (P3-97, N6-97, R1-97, 3V1-59E, and 3V3-59E) in ...

Automated facies classification in borehole log data [PDF]

open access: yes, 2021
Seismic facies inversion relies on accurate facies-specific elastic parameter models determined from borehole data. We introduce a modified Expectation Maximisation algorithm for simultaneous facies classification and fitting of rock physics models.Open ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
