A number of hydrocarbon discoveries have been made recently in the Flemish Pass Basin and Central Ridge, offshore Newfoundland, Canada, but there is only limited geological information available. The primary goal this study was to determine sedimentary provenance paleodrainage patterns mudstones sandstones from Upper Jurassic Rankin Formation, including Lower Kimmeridgian Source Rock (organic-r...

19 Detrital-zircon analysis of sandstones interbedded with ca 464 Ma ignimbrites in 20 the lower Mweelrea Formation of the South Mayo Trough, western Ireland, 21 suggests Ordovician source-rock provenance that corresponds to two distinct 22 volcanic-arc phases on the Laurentian margin. East-derived sandstones contain a 23 suite of zircons with a mean age of ca 487 Ma that suggests derivation fr...

An approximately 3500 m thick stratigraphic section was detailed surveyed in order to study the tectono-sedimentary evolution of Ñirihuau Formation along Arroyo Las Bayas, northern sector basin, North Patagonian Andes. A total amount 29 lithofacies were recognized and used define facies, grouped into six facies associations (FA) that reflect different paleoenvironments: FA1 (Gray brownish congl...

in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...

Abstract Detrital zircon U-Pb studies of mudstone provenance are rare but may preferentially fingerprint distal sources. To examine this issue, Pierre Shale and Trinidad Sandstone deposited in a Late Cretaceous deltaic environment the Raton Basin, Colorado (USA), were measured for detrital age by laser ablation–inductively coupled plasma–mass spectrometry. Two major peaks at ca. 70 1690 Ma foun...

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...

Introduction: The 23 km diameter and ~39 Ma Haughton impact structure, located on Devon Island, Canada, was formed in Cambrian to Silurian sedimentary rocks and Precambrian crystalline basement gneissic rocks [1]. Previous studies show that Haughton sandstones (" Hs ") have undergone melting at low pressures (<20 GPa; [2]). However, even though the presence of planar deformation features (PDFs)...
