摘要:Abstract(#br)We have applied the unspiked K-Ar and the 40 Ar/ 39 Ar methods to samples precisely collected and localised, on both Central Indian Ridge flanks, to test their effectiveness and reliability when applied to the dating of recent (i.e. less than 1 Ma) MORBs. Twenty...

摘要:Abstract(#br)High-resolution, near-seafloor magnetic data have been acquired over the 16°N hypermagmatic segment of the East-Pacific Rise using an Autonomous Underwater Vehicle. This survey proves to be ideal to test the relative efficiency of various inversion methods appli...

摘要:Abstract(#br)Both continental margins of Australia and Antarctica exhibit a very clear gravity anomaly on the satellite free-air gravity data. The detailed sinuosity of these first-order conjugate features matches perfectly, suggesting that they are the signature of the init...

摘要:Abstract(#br)The separation of South America from Africa during the Cretaceous is poorly understood due to the long period of stable polarity of the geomagnetic field, the Cretaceous Normal Superchron (CNS, lasted between ∼121 and 83.6 Myr ago). We present a new identificati...

摘要:Abstract(#br)This paper aggregates the main basic data acquired along the Chile Triple Junction (CTJ) area (45°–48°S), where an active spreading center is presently subducting beneath the Andean continental margin. Updated sea-floor kinematics associated with a comprehensive...

摘要:Abstract(#br)The interaction between the Foundation hotspot and the Pacific–Antarctic Ridge (South Pacific) is one of the two known cases where a ridge is approaching a hotspot. This ridge–hotspot relative movement results in a change in the morphology of the volcanoes along...

摘要:Abstract(#br)To better understand the recent motion of the Pacific plate relative to the Rivera plate and to better define the limitations of the existing Rivera–Pacific plate motion models for accurately predicting this motion, total-field magnetic data, multibeam bathymetr...

摘要:Abstract(#br)The direction of convergence between the Rivera and North American plates becomes progressively more oblique (in a counter-clockwise sense as measured relative to the trench-normal direction) northwestward along the Jalisco subduction zone. By analogy to other s...

摘要:Abstract(#br)The structural organization of a giant mafic dyke swarm, the Okavango complex, in the northern Karoo Large Igneous Province (LIP) of NE Botswana is detailed. This N110°E-oriented dyke swarm extends for 1500 km with a maximum width of 100 km through Archaean base...

摘要:Abstract(#br)High‐resolution magnetic surveys acquired near the seafloor show that active basalt‐hosted hydrothermal sites are associated with zones of lower magnetization. This observation may reflect the thermal demagnetization of a hot hydrothermal zone, the alteration of...
