3D palaeogeographic reconstructions of the Phanerozoic versus sea-level and Sr-ratio variations: Discussion

open access: yesJournal of Palaeogeography, 2015
Veacute;rard et al. (2015, Journal of Palaeogeography, 4(1): 64-84) claim that their global geodynamic model allows one to reconstruct the surface features of topography on land and in adjacent oceans (i.e., paleobathymetry) anywhere on the globe and at ...

Controlling stress state of a hoisting shaft frame in the context of specific freezing process [PDF]

open access: yes, 2018
Purpose is to obtain regularities of a stress state of such multilayer system as neighbourhood rock mass – frozen soil – hoisting shaft frame in the process of numerical analysis to control a frame state with the selection of efficient parameters ...

Behaviour pattern of rock mass haulage energy intensity in deep pits

open access: yesГорные науки и технологии, 2023
A significant portion of mineral deposits developed by open-pit mining is opened to the full depth by road transport ramps without the use of combined transport.

Composition depth profile analysis of electrodeposited alloys and metal multilayers: the reverse approach [PDF]

open access: yes, 2011
The reverse depth profile analysis is a recently developed method for the study of a deposit composition profile in the near-substrate zone. The sample preparation technique enables one to separate the deposit and a thin cover layer from its substrate ...

Flow dynamics of Nankai Trough submarine landslide inferred from internal deformation using magnetic fabric

open access: yesGeochemistry, Geophysics, Geosystems, 2014
Submarine landslide deposits in an active subduction zone were investigated by Integrated Ocean Drilling Program Expedition 333 as the “Nankai Trough Submarine Landslides History.” The expedition recovered a Pleistocene to Holocene sequence of stacked ...

Extremes in dune preservation: controls on the completeness of fluvial deposits [PDF]

open access: yes, 2015
Understanding sedimentary preservation underpins our ability to interpret the ancient sedimentary record and reconstruct palaeoenvironments and palaeoclimates.

Bed-parallel slip: Identifying missing displacement in mass transport deposits [PDF]

open access: yesJournal of Structural Geology, 2020
Abstract Bed-parallel slip (BPS), where neighbouring beds slide past one another along bedding planes, is notoriously difficult to identify without reference to pre-existing features such as steep faults or dykes that act as markers to record BPS offset.

Giant slope scars and mass transport deposits across the Rhodes Basin, eastern Mediterranean: Depositional and tectonic processes [PDF]

open access: yesSedimentary Geology, 2021
Abstract High-resolution multichannel seismic reflection profiles and multibeam mosaic maps of the seafloor are used to document the presence of two prominent regions representing major sediment failure(s) and the subsequent gravity-driven mass transport across the southwestern continental margin of Anatolia.

Exotic clasts, debris flow deposits and their significance for reconstruction of the Istebna Formation (Late Cretaceous – Paleocene, Silesian Basin, Outer Carpathians)

open access: yesGeologica Carpathica, 2017
The different types of calcareous exotic clasts (fragments of pre-existing rocks), embedded in the Paleocene siliciclastic deposits of the Istebna Formation from the Beskid Mały Mountains (Silesian Unit, Western Outer Carpathians), were studied and ...

Intensification of technological processes in drilling and blasting operations during open-cut mining in Kyzylkum region [PDF]

open access: yes, 2018
Purpose. It is found that for long term standing, the pit bench profile is close to the boundary of the disturbed zone. Therefore, long stability of the bench can be estimated in respect to the size of the disturbed area and the boundary of residual ...
