Hemipelagites: processes, facies and model

Geological Society Special Publication, 1998
Abstract Detailed sedimentological studies have been carried out on Pleistocene to Recent sediments from the Makran margin and on Miocene to Recent sediments from the Oman margin of the NW Indian Ocean. In both area, hemipelagites make up c. 50% of the succession, being closely interbedded with turbidites (

Aragonite dissolution, sedimentation rates and carbon isotopes in deep-water hemipelagites (Livinallongo Formation, Middle Triassic, northern Italy)

Sedimentary Geology, 2005
Hemipelagic nodular limestones are a widespread facies in the Triassic of the Tethys, often considered as being deposited at rather constant sedimentation rates. The aim of this paper is to investigate the sedimentation rate variability in a case-study from the Middle Triassic of the Dolomites, northern Italy, and to suggest possible causes.

Deciphering hemipelagites from homogenites through anisotropy of magnetic susceptibility. Paleoseismic implications (Sea of Marmara and Gulf of Corinth)

Sedimentary Geology, 2013
Abstract In closed marine basins and large lakes, gravity re-depositional processes often result in specific turbidites with two abruptly separated layers: a coarse graded lower term and an upper homogenous fine-grained term. An additional mixed term generally occurs in between, indicating to and from particle displacements.

The Weddell Sea: contourites and hemipelagites at the northern margin of the Weddell Gyre

Geological Society Memoir, 2002
Abstract Fine-grained contourites and hemipelagites occur in the northern Weddell Sea, deposited from the Weddell Gyre. Where bottom currents are intensified over the slope, sandy and silty contourites have been deposited above 2000 m water depth. Mudwaves are generally uncommon, but are present in Powell Basin.

Aragonite dissolution, sedimentation rates and carbon isotopes in deep-water hemipelagites (Livinallongo formation, Middle Triassic, northern Italy)

Sedimentary Geology, 2007
In a recent contribution to this journal Preto et al. (2005) present stratigraphic results and correlations of sediments of the Middle Triassic Buchenstein basin (Buchenstein/Livinallongo Fm.) of the Southern Alps. The data are then used for quantifying the rates of pelagic sedimentation and for the interpretation of observed dissolution features ...
