Growth , structure , instability and collapse of Canarian volcanoes and comparisons with Hawaiian volcanoes
Recent onshore and offshore investigations in the Canarian archipelago, especially in the western islands of La Palma and El Hieno, have greatly improved the understanding of the genesis and evolution of these islands and allow interesting comparisons with other hotspot-induced oceanic island volcanoes, especially the Hawaiian archipelago. Genesis induced by hotspot activity and, consequently, ...

15 صفحه اولAn Intrusive Dike Origin for Iapetus’ Enigmatic Ridge?
Introduction: The striking equatorial ridge of Iapetus was discovered by the Cassini mission [1]. 18 km high, 100-200 km wide and 1600 km long, this ridge accurately encircles almost 1/3 of the satellite’s equator. Iapetus is also unusual in that its shape is out of equilibrium with its current slow rotation rate: Best fits to its second order harmonic shape indicate that its equatorial bulge i...
متن کاملLayering in the wall rock of Valles Marineris: intrusive and extrusive magmatism
[1] High-resolution images of the walls exposed in Valles Marineris reveal variations in appearance and degree of layering indicating various lithologies comprise the Tharsis plateau. The layered wall rock has been proposed to result from effusive flood basalt volcanism or interbedded sediments and volcanics. We present observations of unlayered rock that indicate layering extends to a greater ...
