Geochronology and thermochronology on detrital material provides unique constraints on sedimentary provenance, depositional ages, and orogenic evolution of source terrains. In this paper we describe a method and case-studies of measurement of both U/Pb and (U-Th)/He ages on single crystals of zircon that improves the robustness of constraints in each of these areas by establishing both formatio...

Detailed sedimentological analysis of a prodeltaic turbidite unit within the Pennsylvanian Minturn Formation provides insight into the nature of fan-delta deposition, and allows reconstruction of paleogeographic and paleoclimatic conditions within a tectonically active cratonic basin. The formation, a thick succession of fan-delta deposits, exhibits a complex stratigraphic architecture of alluv...

The mineralogy of S-bearing phases, S-contents, and S-isotopic compositions of sediments and interstitial waters were determined for three cores drilled during Leg 129 in the western Pacific. Pelagic clays, chalks, and radiolarites generally contain 350-1200 ppm S, with essentially all S present as sulfate. Volcanogenic turbidite units contain about 400 ppm S, with about 10%-20% of total sulfur...

The use of hybrid techniques aims at constructing new models which enable us to overcome the existing limitations in the reproduction of curvilinear structures. Improvements on a deepwater turbidite reservoir model combining several primary modeling methods are presented. In this approach, multiple points geostatistics (MPS) plays an important role in simulating and conditioning the realization...

The fill of trench-slope basins is complex, varying temporally, laterally, and longitudinally. New data from the Neogene stratigraphy Akitio Sub-basin, Wairarapa, are presented to investigate such variation. preserved basin spans an area 70 km long by 10 wide, representing deposits a basin. Integration sedimentological, micropalaeoentological, geological mapping charts evolution. Over 15 strata...
