Ichnocoenoses of a turbidite sole
Ichnos, 1991Specimens of 13 ichnospecies and their spatial distributions were analyzed on a spectacular cast of a turbidite sole surface (2.9 m2), from Eocene flysch of Spain. The distribution tends to be patchy. Except for postturbidite Granularia, no intraspecies overcrossing was observed.

Abstract Deep-water sedimentation is currently a major focus of both academic research and industrial interest. Recent studies have emphasized the fundamental influence of seafloor topography on the growth and morphology of submarine ‘fans’: in many turbidite systems and turbidite hydrocarbon reservoirs, depositional system development has ...

Turbidite Giants - Lessons from the World's 40 Largest Turbidite Discoveries
Proceedings, 1998What are the ingredients that make a giant turbidite field? This question is important as industry focuses on global deep water plays, because, although turbidites are not the only reservoir type of deep water plays, they are the primary reservoir type in deep water. This has been recently reinforced by deep water drilling in Brazil, the Gulf of Mexico,

Scaling in Turbidite Deposition
SEPM Journal of Sedimentary Research, 1994ABSTRACT We propose that the distribution of layer thicknesses of turbidite deposits that show minimal erosional truncation and amalgamation should obey the power law N(h) h-B, where N(h) is the number of layers of thickness greater than h and B 1. We support this proposal with two sets of observations, one from formation-microscanner images obtained ...

Vacillatory turbidites, Barbados
Sedimentary Geology, 1988Abstract A vacillatory turbidite is one containing Bouma sequence divisions that repeat within a bed; it presumably results from a single flow event or several closely-related events (for example, retrogressive slope failure). The most common vacillations or repetitions in such turbidites on Barbados are between T b and T c intervals (T bcbc , for ...

The position of graptolites in turbidites
Sedimentary Geology, 1969Abstract This paper shows with two examples, from localities of unquestionable turbidite emplacement, that all of the pelitic zone (zone ρ of Bouma, 1962) is deposited by turbidity processes. This zone is richly fossiliferous in the Ordovician strata of Victoria, Australia, and the graptolites can be shown to be oriented, to the highest horizon, in a

Orleansville Turbidite: ABSTRACT
AAPG Bulletin, 1982The Orleansville earthquake in 1954 produced a turbidity current on the Algerian Mediterranean margin and adjacent South Balearic basin sea floor which broke five telephone cables. The report of this event represented a cornerstone in the evolution of turbidity current theory.

Canadian Journal of Earth Sciences, 1973
It is becoming increasingly clear that this paper by Walker (1970)l is deservedly going to serve as an important reference for turbidite workers. I feel, therefore, that it is worth commenting, at this rather late stage, on the following paragraph (p. 233 ) : "A list of lateral changes related to the ABC index has been published by Lovell (1969a), but ...

Areal and lateral changes in a major trailing margin turbidite—The Black Shell Turbidite
Geo-Marine Letters, 1987The Black Shell Turbidite on the Hatteras Abyssal Plain covers at least 50,000 km2, with a volume over 100 km3. It was initiated by failure on the upper continental slope and was channeled southeast through Hatteras Canyon to the plain. Provenance related shape studies indicate that on the plain the current separated into a sandy Phase which flowed S ...

Unconformities in Turbidite Sequences
The Journal of Geology, 1959Unconformities usually imply subaerial erosion. It is suggested, from submarine geological data, that turbidite sequences may contain unconformities which do not indicate subaerial erosion but are due to turbidity-current scour. Included rock fragments and derived fossils in such sequences may not indicate that the source rocks were being subaerially ...
