Iron-manganese mineralization in Eocene deposits of Parashka skyba (Skybov nappe, Ukrainian Carpathians)

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2022
Formulation of the problem. Modern advances in oceanographic studies of sedimentogenesis and orogenesis open up opportunities for in-depth study of rocks by fold-nappe systems, including the Carpathian region. Review of previous research.

Identification of deep subaqueous co-seismic scarps through specific coeval sedimentation in Lesser Antilles: implication for seismic hazard [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2012
During the GWADASEIS cruise (Lesser Antilles volcanic arc, February–March 2009) a very high resolution (VHR) seismic-reflection survey was performed in order to constrain Late Quaternary to Present faulting.

Palaeobiology and taphonomy of the rangeomorph Culmofrons plumosa

open access: yesPalaeontology, Volume 66, Issue 4, July/August 2023., 2023
Abstract The deep marine Ediacaran fossil record of Avalonia is dominated by the Rangeomorpha, a clade characterized by up to four orders of fractal‐like branching. Despite their abundance, morphological diversity and the recent increase in Ediacaran studies, aspects of their palaeobiology, palaeoecology and phylogenetic position in the tree of life ...

Tectonic Evolution of a Sedimented Oceanic Transform Fault: The Owen Transform Fault, Indian Ocean

open access: yesTectonics, Volume 42, Issue 5, May 2023., 2023
Abstract The Owen transform fault (OTF) connecting the Sheba and the Carlsberg spreading ridges in the Indian Ocean currently forms the active plate boundary between India and Somalia plates. This 330‐km‐long transform fault is by far the longest transform fault along the India‐Somalia plate boundary and its valley is buried under the thick distal ...

The Bottom Current Sediments (Contourites) in the Upper Cretaceus Deep-Water Deposits in the Northeeastern Part of Žumberak (Croatia)

open access: yesGeologia Croatica, 2010
The Upper Cretaceous deep marine deposits in NE parts of Žumberakcontain sediments deposited by bottom currents - muddy, sandy andsandy-gravelly contourites. The complete (negative-positive) sequencesand incomplete (negative-positive) sequences have been

Contourite on the Limpopo Corridor, Mozambique margin: Long‐term evolution, facies distribution and Plio‐Quaternary processes

open access: yesSedimentology, Volume 70, Issue 3, Page 728-758, April 2023., 2023
Abstract Bottom currents are key processes that contribute to the shaping of submarine slopes, with the redistribution of sediments in contourite systems. Despite numerous recent studies on contourite systems, the complexity and diversity of these sedimentary systems are still not fully understood and often underestimated.

The influence of creeping slope failure on turbidity current behaviour

open access: yesSedimentology, Volume 70, Issue 2, Page 335-361, February 2023., 2023
ABSTRACT Erosional scars, slumps, slides and debrites (mass‐transport deposits) on submarine slopes form relief that influences turbidity current behaviour. However, the interaction of mass‐transport deposit emplacement kinematics (i.e. rapid emplacement versus creep), the morphology of the evolving seafloor topography and subsequent flow types is ...

Contractional kink bands formed by stress deflection along pre-existing anisotropies? Examples from the Anglo-Brabant Deformation Belt (Belgium) and the North Dobrogea Orogen (Romania) [PDF]

open access: yes, 2008
Kink bands within two slate belts, the Anglo-Brabant Deformation Belt (Belgium) and the North Dobrogea Orogen (Romania), reveal similar problems with respect to linking kink band geometries to expected palaeostress directions.

Environmental Conditions in a Carpathian Deep Sea Basin During the Period Preceding Oceanic Anoxic Event 2 - A Case Study from the Skole Nappe

open access: yesGeologica Carpathica, 2015
Hemipelagic green clayey shales and thin muddy turbidites accumulated in a deep sea environment below the CCD in the Skole Basin, a part of the Outer Carpathian realm, during the Middle Cenomanian.
