The surface mechanical boundary conditions for most of our models are shear stress free (free slip), such that plate velocities are driven self-consistently by density contrasts within the mantle (Ricard and Vigny, 1989). The lithosphere in our models is defined rheologically as a relatively stiff layer from the surface to 100 km depth that is “broken” by weak zones of reduced viscosity, as in ...

Four new species are assigned to the genus Teretia Norman, 1888 in the family Raphitomidae Bellardi, 1875 and herein described: Teretia neocaledonica sp. nov., T. sysoevi sp. nov., T. tongaensis sp. nov. from the southeastern Pacific and Teretia tavianii sp. nov. from the Gulf of Aden. The new species represent the first Indo-Pacific record of a genus previously known in the recent molluscan fa...

The collision of India with Asia, one of the most profound tectonic events to have occurred in past 100 m.y., is thought to have had geological, geochemical, and climatological consequences of global extent. Surprisingly the age of initiation of this collision remains poorly constrained. Estimates range from the Late Cretaceous (.65 Ma) to latest Eocene (,40 Ma), with little consensus in betwee...

Microproblematica are microfossils whose suprageneric taxonomic status is unknown. Many microproblematica display an encrusting way of life and can therefore be included in the group of “micro-encrusters” that during the Upper Jurassic were conspicuous components of microbial carbonate crusts (e.g. LEINFELDER et al., 1993; SCHMID, 1996; DUPRAZ & STRASSER, 1999, 2002). These forms are widespread...

Sequence data derived from four markers (the nuclear RP1 and Aldolase and the mitochondrial 16S rRNA and cytochrome b genes) were used to determine the phylogenetic relationships among 32 species belonging to the genus Hippocampus. There were marked differences in the rate of evolution among these gene fragments, with Aldolase evolving the slowest and the mtDNA cytochrome b gene the fastest. Th...

The Proto-Tethys Ocean played an important role in the formation and evolution of East Asian continental blocks, final closure may have led to first assembly nearly all blocks at northern margin Gondwana. However, controversy remains about reconstruction Tibetan Plateau is located Gondwana recorded entire tectonic from rift drift subduction collision during early Paleozoic. Therefore, it region...
