The Jurassic Ligurian Tethys, a fossil ultraslow‐spreading ocean: the mantle perspective
Geological Society Special Publication - Tập 293 Số 1 - Trang 11-34 - 2008
Giovanni B. Piccardo
Abstract Alpine–Apennine ophiolites derive from the Jurassic Ligurian Tethys oceanic basin formed by lithosphere extension and failure in the pre-Triassic Europe–Adria system. The basin was floored by mantle peridotites and was characterized by along-axis alternation of avolcanic and volcanic segments. Lithosphere extension and thinning caused asthenosphere adiabatic upwelling and decompressional ... hiện toàn bộ
A combined chemical and Pb-Sr-Nd isotope study of the Azores and Cape Verde hot-spots: the geodynamic implications
Geological Society Special Publication - Tập 42 Số 1 - Trang 231-255 - 1989
G.R. Davies, R. A. Cliff, Michael J Norry, David C. Gerlach
Summary The mafic lavas of the Azores and Cape Verde Islands are of a highly varied composition, reflecting a complex history of magma genesis and a variety of source compositions. The lavas of the Cape Verde Islands are characteristically highly silica undersaturated, with alkali-rich ankaramites, larnite-normative melilitites and carbonatites. In contrast, the lavas of the Azores vary from stron... hiện toàn bộ
Tectonic and stratigraphic evolution of Zagros and Makran during the Mesozoic-Cenozoic: introduction
Geological Society Special Publication - Tập 330 Số 1 - Trang 1-4 - 2010
Pascale Leturmy, Cécile Robin
Overview of tectonic settings related to the rifting and opening of Mesozoic ocean basins in the Eastern Tethys: Oman, Himalayas and Eastern Mediterranean regions
Geological Society Special Publication - Tập 282 Số 1 - Trang 325-388 - 2007
Alastair H.F. Robertson
Abstract A combination of geophysical studies and deep-sea drilling have in the past suggested that orthogonally rifted margins fall into two end-members: volcanic-rifted margins (e.g. eastern Greenland) and non-volcanic rifted margins (e.g. Iberia–Newfoundland conjugate). This paper explores the rifted margins of the Eastern Tethys stretching from the Eastern Mediterranean, through Oman to the Hi... hiện toàn bộ
Interactive inverse methodology applied to stratigraphic forward modelling
Geological Society Special Publication - Tập 239 Số 1 - Trang 147-156 - 2004
Chris Wijns, Thomas Poulet, Fabio Boschetti, Chris Dyt, Cedric M. Griffiths
Abstract An effective inverse scheme that can be applied to complex 3-D hydrodynamic forward models has so far proved elusive. In this paper we investigate an interactive inverse methodology that may offer a possible way forward. The scheme builds on previous work in linking expert review of alternate output to rapid modification of input variables. This was tested using the SEDSIM 3-D stratigraph... hiện toàn bộ
Rootless cones on Mars: a consequence of lava-ground ice interaction
Geological Society Special Publication - Tập 202 Số 1 - Trang 295-317 - 2002
S. A. Fagents, P. D. Lanagan, R. Greeley
Abstract Fields of small cratered cones on Mars are interpreted to have formed by rootless eruptions due to explosive interaction of lava with ground ice contained within the regolith beneath the flow. Melting and vaporization of the ice, and subsequent explosive expansion of the vapour, act to excavate the lava and construct a rootless cone around the explosion site. Similar features are found in... hiện toàn bộ
Deformation processes in unconsolidated sands
Geological Society Special Publication - Tập 29 Số 1 - Trang 11-24 - 1987
Geraint Owen
Summary Deformation in unconsolidated sands requires the action of a deformation mechanism to reduce sediment strength and a driving force to induce deformation. Deformation mechanisms include liquefaction and fluidization and are reflected in the style of deformation and grain orientation fabrics. They are initiated by a trigger, including groundwater movements, wave action and seismic shaking. D... hiện toàn bộ
The liquification and remobilization of sandy sediments
Geological Society Special Publication - Tập 94 Số 1 - Trang 63-76 - 1995
Robert J. Nichols
Abstract A number of large, unusually shaped sandbodies have been interpreted from three-dimensional seismic data of hydrocarbon-bearing Tertiary submarine fan deposits of the North Sea. The unusual sandbody shape is considered to have resulted from post-depositional liquification of turbidite deposits. An understanding of liquification processes may therefore be important in delineating reservoir... hiện toàn bộ
The metamorphism of the Tibetan Series from the Manang area, Marsyandi Valley, Central Nepal
Geological Society Special Publication - Tập 74 Số 1 - Trang 357-374 - 1993
Christian Schneider, L. Masch
Abstract In the Manang area a distinctive metamorphic zonation with grade increasing downward to deeper structural levels of the Tibetan Series can be observed. The first appearance of prograde biotite/phlogopite introducing the metamorphic zonation can be located in the Devonian Tilicho Pass Formation. The Silurian Dark Band Formation contains prograde titanite. Tremolite is not observed to the w... hiện toàn bộ
Late Permian anoxia in central East Greenland
Geological Society Special Publication - Tập 58 Số 1 - Trang 275-290 - 1991
Stefan Piasecki, Lars Stemmerik
Abstract The Upper Permian Foldvik Creek Group of the East Greenland Basin provides excellent possibilities for studying regional anoxia, because the basinal, anoxic facies of the Ravnefjeld Formation are well exposed throughout this 400 km long and more than 80 km wide basin. The shales of the Ravnefjeld Formation are dominated by two units of laminated, organic-rich, calcareous mudshales. The ab... hiện toàn bộ
