Proximal to distal grain‐size distribution of basin‐floor lobes: A study from the Battfjellet Formation, Central Tertiary Basin, Svalbard

open access: yesThe Depositional Record, 2022
The grain‐size distribution of sediment particles is an important aspect of the architecture of submarine fans and lobes. It governs depositional sand quality and reflects distribution of particulate organic carbon and pollutants.

The Origin and 3D Architecture of a Km-Scale Deep-Water Scour-Fill: Example From the Skoorsteenberg Fm, Karoo Basin, South Africa

open access: yesFrontiers in Earth Science, 2021
Scours, and scour fields, are common features on the modern seafloor of deep-marine systems, particularly downstream of submarine channels, and in channel-lobe-transition-zones.

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

Tectonic-sedimentary approach as a basis to study thinly bedded reservoirs with complex geological structure

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2020
The article is focused on studies of features of the formation of heterogeneous geological structures namely the "lake-type" turbidite reservoirs, with complex thin-layered structure.

Inverse modeling of turbidity currents using an artificial neural network approach: verification for field application [PDF]

open access: yesEarth Surface Dynamics, 2021
Although in situ measurements in modern frequently occurring turbidity currents have been performed, the flow characteristics of turbidity currents that occur only once every 100 years and deposit turbidites over a large area have not yet been elucidated.

Sedimentary processes and architecture of Upper Cretaceous deep-sea channel deposits : a case from the Skole Nappe, Polish Outer Carpathians [PDF]

open access: yes, 2018
Deep-sea channels are one of the architectonic elements, forming the main conduits for sand and gravel material in the turbidite depositional systems.

Supercycle in great earthquake recurrence along the Japan Trench over the last 4000 years

open access: yesGeoscience Letters, 2018
On the landward slope of the Japan Trench, the mid-slope terrace (MST) is located at a depth of 4000–6000 m. Two piston cores from the MST were analyzed to assess the applicability of the MST for turbidite paleoseismology and to find out reliable ...

Turbidites as indicators of paleotopography, Upper Miocene Lake Pannon, Western Mecsek Mountains (Hungary)

open access: yesGeologica Carpathica, 2015
The floor of Lake Pannon covering the Pannonian Basin in the Late Miocene had considerable relief, including both deep sub-basins, like the Drava Basin, and basement highs, like the Mecsek Mts, in close proximity.

The Turbidite Problem* [PDF]

open access: yesNew Zealand Journal of Geology and Geophysics, 1969
Abstract The turbidity current hypothesis has met with much support as well as severe criticism. Dogmatic statements in support of this hypothesis are not uncommon in the literature and a clear distinction between fact and inference is not always made.

Depositional architecture of marginal multiple-source ramp of the Magura Basin (Eocene Flysch formation, Outer Western Carpathians)

open access: yesGeologica Carpathica, 2018
The Zembrzyce Beds were studied to interpret the environments and facies in the western part of the Siary Subunit. New sedimentological data were obtained for the reconstruction of the depositional architecture of the Zembrzyce Beds.
