The Aegean–Hellenic arc is a deformed sector of long heterogeneous orogenic system (Tethyan belt), constituted by an inner old metamorphic crystalline core flanked younger chains European and African affinity, running from the Anatolian to Pelagonian zones. Due convergence between Arabian promontory Eurasian continental domain, that belt has undergone westward extrusion, accommodated oroclinal ...
the kahnuj ophiolitic complex, a part of the jazmurian ophiolitic belt, is located on the western boundary of the jazmurian depression and is bounded by two major fault systems. there is a well-preserved, ophiolite pseudostratigraphy of early cretaceous to early palaeocene age and has a bearing on the mesozoic development of southeastern part of iran and adjacent region. the kahnuj ophiolitic c...
Field mapping and geochronologic and thermobarometric analyses of the Gurla Mandhata area, in southwest Tibet, reveal major middle to late Miocene, east-west extension along a normal-fault system, termed the Gurla Mandhata detachment system. The maximum fault slip occurs along a pair of low-angle normal faults that have caused significant tectonic denudation of the Tethyan Sedimentary Sequence,...
A new species of the macrourine genus Nezumia is described from specimens collected from the crest of Fieberling Guyot in the eastern North Pacific Ocean. The new species is distinguishable from all other Nezumia species chiefly on the basis of a high number of pelvic fin rays, a relatively high number of first dorsal fin soft rays, a steep blunt snout lacking scales ventrally, a relatively wea...
Stylophora pistillata is a widely used coral "lab-rat" species with highly variable morphology and a broad biogeographic range (Red Sea to western central Pacific). Here we show, by analysing Cytochorme Oxidase I sequences, from 241 samples across this range, that this taxon in fact comprises four deeply divergent clades corresponding to the Pacific-Western Australia, Chagos-Madagascar-South Af...
Thomas M. Iliffe Bermuda Biological Station for Research Ferry Reach GE 01, Bermuda Significant biological and geological discoveries have resulted from the use of specialized cave diving techniques for the exploration and study of anchialine caves. Many new and higher taxa of troglobitic organisms have been found, some of which are relic "living fossils". Marine troglobites have at least three...
The Early Cretaceous Greater Ontong Java Event in the Pacific Ocean may have covered ca. 1% of the Earth's surface with volcanism. It has puzzled scientists trying to explain its origin by several mechanisms possible on Earth, leading others to propose an extraterrestrial trigger to explain this event. A large oceanic extraterrestrial impact causing such voluminous volcanism may have traces of ...
The Paleocene-Eocene Thermal Maximum (PETM) is associated with major extinctions in the deep ocean, and significant paleogeographic ecological changes surface ocean terrestrial environments. However, impact of environmental change on shelf biota less well understood. Here, we present a new PETM record low paleolatitude shallow-marine carbonate platform from Meghalaya, NE India (eastern Tethys)....
Nuclear and mtDNA sequences from selected short-looped terebratuloid (terebratulacean) articulate brachiopods yield congruent and genetically independent phylogenetic reconstructions by parsimony, neighbour-joining and maximum likelihood methods, suggesting that both sources of data are reliable guides to brachiopod species phylogeny. The present-day genealogical relationships and geographical ...
