Role of Froude supercritical flow in active margin basin-floor fans, The
This dissertation focuses on the active margin basin floor fan and tests the hypothesis that whether Froude supercritical flow and a high degree of channelization are common features in basin floor fans, even in a distal part. The Froude supercritical flow may control the architecture and …

Late Pleistocene-Holocene sedimentary processes at the active margin of South-Central Chile : marine and lacustrine sediment records as archives of tectonics and climate variability
Active continental margins are affected by complex feedbacks between tectonic, climate and surface processes, the intricate relations of which are still a matter of discussion. The Chilean convergent margin, forming the outstanding Andean subduction orogen, constitutes an ideal natural laboratory …

Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
… by orogenic pulses derived from the Samfrau active margin throughout the Mesozoic. The associated intracratonic E-W extension caused the formation of grabens and conjugated oblique-slip zones. The generation of voluminous flood basalts marks the climax of intracratonic extension that was …

The Skiddaw Group of Cumbria : early Ordovician Turbidite sedimentation and provenance on an evolving microcontinental margin.
… Scar borehole is supported, but a continental margin volcanic arc provenance and deposition as a coarse grained lobe of a submarine fan suggests the dispersal system was separate from that of the Skiddaw Group. Lithological comparison is made with contemporaneous strata of southeast Ireland. …

EVOLUTION OF THE EASTERN ALPS FROM THE PALEOZOIC ONWARD: CONSTRAINTS AND INSIGHTS FROM THE (ULTRA)BASIC ECLOGITIC COMPLEX OF MILCHENKAR ÖTZTAL-STUBAI COMPLEX (EASTERN ALPS, TYROL, AUSTRIA)
… located further east along the peri-Gondwana margin. The subsequent metamorphic evolution of the NEZ is characterized by a pervasive, although partially retrogressed, high pressure event resulting in the eclogitization of the (ultra)basic complex completely affecting the more evolved gabbroic …

Geochemical and Geochronological Constraints on the Origin and Evolution of Rocks in the Active Woodlark Rift of Papua New Guinea
<p>Tectonically active regions provide important natural laboratories to glean information that is applicable to developing a better understanding of the geologic record. One such area of the World is Papua New Guinea, much of which is situated in an active and transient plate boundary zone. The …
