The taxonomy, paleo-ecology and biogeography of the highly diverse "Cabarruyan" fauna are explored further. Eight species of three vetigastropod families are discussed here, one of which is described as new: Zeidora geigeri nov. spec. The other seven species were previously described from Recent material and three of these are also known from other fossil deposits. Most of the species still occ...

A number of Paleo-Indian artifacts found in Western Wisconsin lithic assemblages were observed to be made of an unidentified olive green colored chert. A macroscopic examination of these artifacts, and comparison with known possible sources suggested that the material might be Silurian Chert Type II from the Door Pennisula in eastern Wisconsin. Attributed analysis and comparison with lithic deb...

o N-2 o S equatorial strip, for observations (GISST3) and for the CGCMs with no tropical flux adjustment(page 21). More results of the CLIVAR Study of Tropical Oceans Intercomparisons Project (STOIC) can be found in the article by M. Davey et al. on page 21. Note, that there are also results from the Coupled Model Intercomparison Project (CMIP) and the Paleo Climate Modelling Intercomparison Pr...

In this paper we apply spatial database and structure to render the paleo-relief of the Borod Basin. The boreholes data are stored in a spatial database. For the effective surface rendering we use local-Shepard interpolation with variable radius, based on a spatial grid and Delaunay triangulation. The generated pictures are more realistic compared to picture generated by mean of other methods. ...

The South China Block is situated in the Eastern Asian margin. Since Neoproterozoic, its tectonic evolution was constrained by successive consumption-closure processes of Paleo-South China, Proto-Tethys, Paleo-Tethys, and Paleo-Pacific oceans. Studies suggest that this block initially formed Neoproterozoic assembly Yangtze Cathaysia blocks following subduction-accretion Ocean. Then after, it ex...

introduction the occurrence of blueschist metamorphic facies is believed to mark the existence of former subduction zones. this facies is represented in the main constituents of subduction-accretion complexes, where it occurs in separate tectonic sheets, imbricated slices, lenses, or exotic blocks within a serpentinite mélange (volkova et al., 2011). the evidence of the presence and maturity of...

The Ontong Java, Manihiki, and Shatsky oceanic plateaus are among the Earth’s largest igneous provinces and are commonly believed to have erupted rapidly during the surfacing of giant heads of initiating mantle plumes. We investigate this hypothesis by using sediment descriptions of Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) drill cores to constrain plateau subsidence his...
