Non-Volcanic Rifting of Continental Margins: A Comparison of Evidence from Land and Sea

摘要: Non-volcanic continental margins may form up to 30% all present-day passive margins, and remnants of them are preserved in mountain belts. The papers this volume demonstrate the benefits integrating offshore onshore studies, illustrate range information obtained at different scales when comparing evidence from land sea. Data sets collected across a spatial evaluated: thin sections, cores, outcrops, seismic reflection profiles, other geophysical data. outcrop scale is crucial because it enables gulf be bridged between DSDP ODP cores marine There also problem that basins on beneath sea inevitably have had post-rift histories resulting their contrasting elevation. In belts, portions oceanic crust superbly exposed, but dismembered by subsequent compressional tectonics. Off extensional features only been slightly deformed, if all, movements, buried significant thicknesses sediments so can sampled ocean drilling small number points. The first paper reviews synergies occurred investigations eastern North Atlantic non-volcanic similar Mesozoic Alps, some later return theme. However, describing parts world show premature use models based Alps as paradigm for margins. following 25 book grouped under headings: (1) Margin overviews; (2) Exhumed mantle; (3) Tectonics stratigraphy; (4)Numerical extension magmatism.
