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

Вісник 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]

Natural 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

Palaeontology, 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 ...

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

Geologia 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

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

Tectonics, 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 ...

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

Sedimentology, 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 role of compaction contrasts in sediments in décollement initiation in an accretionary prism [PDF]

, 2011
International audienceTo understand how décollements develop into the pristine sedimentary succession entering subduction zones, we have performed mechanical tests on samples from the sediment column entering the Nankai accretionary prism, Japan (ODP ...

Fluid flow through carbonate platforms as evidence for deep-seated reservoirs in Northwest Australia [PDF]

, 2016
Fluid flow features in carbonate platforms of the outer Browse Basin, Northwest Australia, are investigated using 3D seismic and borehole data. During the Cenozoic, the study area evolved from a carbonate ramp to a rimmed platform with isolated carbonate
