Giant hummocks in deep-water marine sediments: Evidence for large-scale differential compaction and density inversion during early burial

Abstract: This paper describes large-scale hummock structures from an Oligocene-Miocene succession in the Faeroe-Shetland Trough, off the northern coast of the United Kingdom. These hummocks have a wavelength of 1–2 km, and an amplitude of about 50 m; they are characterized by a polygonal planform geometry. Two successive depositional packages in this probably pelagic-dominated interval have this form of structural expression, but troughs of the younger set are directly superposed on crests of the older set. They occur at a present-day subsea-bottom depth of about 1000 m, and cover an area of ∼6000 km 2 . This extraordinary structural configuration is attributed to a protracted depositional and deformational history in which a density inversion was established, hummock formation was initiated in response to differential loading above an irregular polygonal fault system, and then subsequent collapse produced syndepositional troughs in the overlying units. These structures are similar in geometry to hummocks described from near-surface sediments in the Norway Basin by P. R. Vogt and are the largest type of density inversion deformation structure yet described from a clastic sedimentary succession.

Multi-layer heat-sealable polypropylene films

Abstract: A heat-sealable multi-layer film structure charactised by consisting essentially of: (i) an outer heat sealable layer (A), a core layer (B), and an outer layer (C), the outer heat sealable layer (A) being coextensively adherent to the upper surface of the core layer (B), and the outer layer (C) being coextensively adherent to the lower surface of the core layer (B) said outer layer (A) being formed from a polymer composition (a) consisting essentially of heat sealable resin compounded with one or more slip additives which are incompatible with polypropylene. (ii) said core layer (B) being derived from a polymer composition (b) consisting essentially of an isotactic polypropylene homopolymer compounded with one or more slip additives which are incompatible with polypropylene, and (iii) said outer layer (c) being formed from a polymer composition consisting essentially of isotactic polypropylene homopolymer in the substantial absence of slip additives; wherein the total amount of slip additive in said film structure is effective to provide the outer surface of outer layer (A) with a coefficient of friction sufficient for high speed heat sealing packaging operations but insufficient to cause substantial hazing of said structure.

Stratigraphy and genesis of a modern shoreface-attached sand ridge, Peahala Ridge, New Jersey

Abstract: We investigated the genesis and evolution of Peahala Ridge, a modern shoreface-attached sand ridge 1 km 6 km in size and 4-7 m in bathymetric relief, through an integrated sedimentologic and stratigraphic study involving vibracoring, box coring, grab samples, high-resolution seismic, paleontology, radiocarbon dating, and oceanographic measurements Near-surface strata of Peahala Ridge include six important stratigraphic units: modern shoreface, upper ridge sand, lower ridge sand, swale/inlet-fill, Middle Holocene back-barrier, and Late Pleistocene strandplain Radiocarbon dating and determination of the stratigraphic relationships indicates that Peahala Ridge formed initially from an ebb-tidal delta associated with a tidal inlet So thwestward migration of the inlet channel, a vector resultant of landward coastal retreat and southerly longshore drift, cut and then filled the swale separating Peahala Ridge from Long Beach Island Following inlet closure, Peahala Ridge developed its present form as a shoreface-attached, shoreline-oblique bathymetric feature Hydrodynamic processes have played a major role in evolution of the ridge, including considerable growth and accretion This combination of long-term (eustatic) and short term (hydrodynamic) factors is the best explanation for the present morphology and internal stratigraphy of Peahala ridge
