Introduction: Although Enceladus has garnered the greatest attention, Saturn’s other icy moons also betray a diverse range of phenomenon (e.g., Rhea‘s ring, Iapetus‘ ridge, Tethys’ fracture). Even in Voyager’s limited global mapping, some cryptic evidence of resurfacing was evident [e.g., 1, 2]. Global mapping by Cassini reveals that a large resurfaced terrain covers much of the leading hemisph...

The end-Permian mass extinction, ∼252 million years ago, is notable for a complex recovery period of ∼5 Myr. Widespread euxinic (anoxic and sulfidic) oceanic conditions have been proposed as both extinction mechanism and explanation for the protracted recovery period, yet the vertical distribution of anoxia in the water column and its temporal dynamics through this time period are poorly constr...

[1] Large impact basins are present on many of the icy satellites of the outer solar system. Assuming that their present-day topography is uncompensated, such basins can cause significant poleward reorientations for slow-rotating satellites. This reorientation may have been accompanied by transient large-amplitude wobble. The largest basins on Tethys, Rhea and Titania are predicted to have caus...

Phylogenetic relationships between the known genera of the order Misophrioida permit the identi® cation of two lineages: one consisting of the family Misophriidae Brady, 1878 which comprises seven genera, and a new, monotypic family, the Palpophriidae Boxshall & Jaume, 1999; the other consisting of another new family, the SpeleophriidaeBoxshall & Jaume, 1999, comprising eight genera. Habitat ex...

Trace elements including mercury, cadmium, selenium, and stable nitrogen isotope ratios (sigma15N) were measured in tissues of Pacific seabirds. Two species of albatross (Diomedea immutabilis, Diomedea nigripes), four species of shearwaters (Puffinus bulleri, Puffinus carneipes, Puffinus griseus, Puffinus tenuirostris), northern fulmar (Fulmarus glacialis), and horned puffin (Fratercula cornicu...

The tectono-stratigraphic evolution of rift systems is at present poorly understood, especially the one preceding onset oceanic seafloor spreading. Improving our understanding complex, polyphase tectonic fossil Alpine Tethys, best calibrated magma-poor worldwide, offers great potential for interpretation distal part global rifted margins, which notoriously lack data. In this paper, we propose a...

marine sequences within several orogenic belts in YunWe report petrological and geochemical data on ultramafic pillow nan, SW China (Figs 1 and 2; Fang et al., 1996). These lavas from Late Palaeozoic marine sequences in Yunnan, SW lavas have been interpreted to be oceanic plateaux or China. These lavas have >26 wt % MgO, euhedral to subhedral seamount eruptive rocks associated with mantle plume...
