1. Cenozoic and Mesozoic Sediments from the Pigafetta Basin, Leg

CENOZOIC AND MESOZOIC SEDIMENTS FROM THE PIGAFETTA BASIN, LEG 129, SITES 800 AND 801: MINERALOGICAL AND GEOCHEMICAL TRENDS OF THE DEPOSITS OVERLYING THE OLDEST OCEANIC CRUST1 Anne Marie Karpoff2 ABSTRACT Sites 800 and 801 in the Pigafetta Basin allow the sedimentary history over the oldest remaining Pacific oceanic crust to be established. Six major deposition stages and events are defined by the main lithologic units from both sites. Mineralogical and chemical investigations were run on a large set of samples from these units. The data enable the evolution of the sediments and their depositional environments to be characterized in relation to the paleolatitudinal motion of the sites. The upper part of the basaltic crust at Site 801 displays a complex hydrothermal and alteration evolution expressed particularly by an ochre siliceous deposit comparable to that found in the Cyprus ophiolite. The oldest sedimentary cover at Site 801 was formed during the Callovian-Bathonian (stage 1) with red basal siliceous and metalliferous sediments similar to those found in supraophiolite sequences, and formed near an active ridge axis in an open ocean. Biosiliceous sedimentation prevailed throughout the Oxfordian to Campanian, with rare incursions of calcareous input during the middle Cretaceous (stages 2, 4, and 5). The biosiliceous sedimentation was drastically interrupted during the Aptian-Albian by thick volcaniclastic turbidite deposits (stage 3). The volcanogenic phases are pervasively altered and the successive secondary mineral parageneses (with smectites, celadonite, clinoptilolite, phillipsite, analcime, calcite, and quartz) define a "mineral stratigraphy" within these deposits. -

Correspondence: Jens K. Ehn ([email protected]) Abstract. The particulate beam attenuation coefficient at 660 nm, cp(660), was measured in conjunction with properties of suspended particle assemblages in August 2009 within the Canadian Beaufort Sea continental margin, a region heavily influenced by sediment discharge from the Mackenzie River. The suspended particulate matter mass concentration (SPM) 3 ranged from 0.04 to 140 g m− , its composition varied from mineral to organic-dominated, and the median particle diameter 5 ranged determined over the range 0.7–120 µm varied from 0.78 to 9.45 µm, with the fraction of particles < 1 µm highest in surface layers influenced by river water or ice melt. A relationship between SPM and cp(660) was developed and used to determine SPM distributions based on measurements of cp(660) taken during summer seasons of 2004, 2008 and 2009, as well as fall 2007. -

Seasonal variations in the magnitude and nature of the vertical particulate organic carbon (POC) fluxes were related to sea-ice thermodynamics on the shelf and local circulation. From October to April, distinct increases in the POC flux coincided with the resuspension and advection of shelf bottom particles by thermohaline convection, windstorms, and/or current surges and inversions. Once resuspended and incorporated into the Benthic Nepheloid Layer (BNL), particles of shelf origin were transported over the slope by the isopycnal intrusion of the BNL into the Polar-Mixed Layer off-shelf. -

Keywords: The ecosystem collapse on the east side of the bay and the prevailing westward longshore current have urbanization resulted in the collapse of the coral and coralline algae population on the west side of the bay. In turn this river plume fine sediment has lead to a decrease in carbonate sediment production through bio-erosion as well as a disintegration nepheloid layer of the dead coral and coralline algae, leading to sediment starvation and increased wave breaking on the herbivorous fish coast and thus increased coastal erosion. -

As a result, we identify the follow- surface parameters.

11. Depositional Facies of Leg 30, Deep Sea Drilling Project Sediment
11. DEPOSITIONAL FACIES OF LEG 30 DEEP SEA DRILLING PROJECT SEDIMENT CORES George deVries Klein, Department of Geology, University of Illinois, Urbana, Illinois ABSTRACT Sediment cores from Leg 30 are subdivided into eight sedimentary facies. The vertical sequence of these facies is controlled by dif- ferences in tectonic setting from which the cores were obtained. Three sites (285, 286, 287) sampled marginal basins, whereas two sites (288, 289) were obtained from an equatorial plateau. The marginal basin facies at Sites 285 and 286 consist of basal sandy turbidites (facies 1) interbedded with mass flow and debris flow conglomerates (facies 2). Within the turbidite intervals, particu- larly at Site 286, an upward increase in flow intensity is suggested from the vertically upward increase in coarse-tail graded bedding which in turn is overlain by an interval of facies 2 conglomerates. Such coarsening-upward facies successions mimic the prograda- tional model of submarine fan evolution documented elsewhere. These clastic facies are overlain by biogenic ooze (some reworked by turbidity currents) of facies 3 and they in turn are capped by abyssal red clays (facies 4). At Site 287 in the Coral Sea Basin, the vertical facies succession consists of basal biogenic oozes (facies 3) overlain by olive clays (facies 6) and capped by silty and clayey turbidites (facies 5) organized into graded cycles. The two sites on the Ontong-Java Plateau show a different facies evolution from a basal facies consisting of reworked and mixed volcanic ash and biogenic sediments and chert (facies 8) to an upper facies consisting of biogenic ooze only (facies 7).
