The Onshore Tunisia Numidian Flysch

4th EAGE North African/Mediterranean Petroleum and Geosciences Conference and Exhibition Tunis 2009, 2009
The study concerns the Oligo-Miocene aged Numidian Flysch which forms the highest structural unit in northern Tunisia and consists of an interbedded unit of highly quartzose sand and shale, which are of turbiditic affinities. An integrated petrographic and geochemical study of this formation was carried out to infer the sandstones provenance, and ...

Flysch: a historical perspective and the Himalayas

Earth-Science Reviews, 1994
Abstract A common question asked by researchers working on orogenic belts is: what is flysch? Varied views have been presented over the years. Any thick succession of sandstone, calcarenite or conglomerate alternating with shale or mudstone, and interpreted as deposited mainly by turbidity currents or mass-flow in a deep water environment within a ...

Palaeogeography of alpine flysch

Palaeogeography, Palaeoclimatology, Palaeoecology, 1983
Abstract Palaoegeography of alpine basins during times of flysch sedimentation is reconstructed from an approach based upon global tectonic constraints, on palinspastic reconstruction from regional geology, and on the sedimentalogy of individual flysch sequences. The opening of the central Atlantic ocean, coincident with the formation of the Western

Geosynclines, Flysch, and Melanges

1974
Abstract My first field work was at Baraboo, Wisconsin, sixty miles north of Madison. And my first stratigraphic research, if one may call it that, was in correlation of sections of Black Earth, St. Lawrence, and Mendota dolomites (Cambrian) in the vicinity of Madison at a time when E. O.

Flysch facies and turbidite sedimentology

Sedimentary Geology, 1970
Abstract The main facies of flysch in the Northern Apennines are listed, the importance of calcareous turbidites being noted. A summary is presented of Italian studies on selected sedimentologic features of the Apennines turbidites: 1. (1) Data on the occurrence of internal sedimentary structures in the turbidite rhythms, in function of thickness

Devonian-Carboniferous pre-flysch and flysch environments in the Circum Pannonian Region

2010
The following Devonian—Carboniferous paleogeographic and Variscan orogenic domains were recognized in the Circum Pannonian Region: Oceanic and arc related environments – Noric Bosnian/Carnic-Dinaric Zone (carbonate dominated passive continental margins) – Inovo Zone (Devonian siliciclastic dominated stable continental margins) – Quartzphyllite ...

Giant Paleodictyon in Eocene flysch

Palaeogeography, Palaeoclimatology, Palaeoecology, 2000
Abstract A giant Paleodictyon gomezi with a maximum mesh diameter of 13 cm and covering more than 0.5 m2 occurs in the lower Eocene flysch near Zumaya. The giant Paleodictyon occurs with flute casts and, therefore, must have been produced deeply in the sediment.

Mechanism of Active Landslides in Flysch

2012
Triggering mechanisms and active landslide dynamics are to a large extent a function of rock and soil types involved. Among different types of active landslides in Slovenia, in the last few years, those in flysch have been of specific research interest.

Attempt at classification of flysch and molasse

International Geology Review, 1966
The author proposes a classification of the types of flysch and molasse based both on descriptive criteria (lithologic and stratigraphic characteristics) and on geological criteria (time and place of deposition). Three categories of flysch and molasse, are distinguished: orthoflysch, paraflysch and pseudoflysch, and correspondingly orthomolasse ...

THE PRE - FLYSCH AND BASAL SHALY FLYSCH DEPOSITION IN THE PARNASSUS - GHIONA ZONE, CENTRAL GREECE

2014
The interruption in deposition during the K/T transition in the Parnassus-Ghiona Zone caused the formation of hardgrounds and intraformational conglomerates in the central parts. During the later part of the early Paleocene to the middle or early part of the late Paleocene a shallow sea covered central Parnassus; stromatolites formed in broad valleys ...
