[1] Mountain building at convergent margins requires tectonic forces that can overcome frictional resistance along large-scale thrust faults and support the gravitational potential energy stored within the thickened crust of the orogen. A general, dynamic model for this process is still lacking. Here we propose that mountain belts can be classified between two end-members. First, those of “slab...
The observation that major Himalayan rivers flow parallel to and down the axis of anticlines oriented transverse to the primary structural grain of the range has puzzled geomorphologists for decades. Although there is a general consensus that the courses of trans-Himalayan rivers predate the Himalayan orogeny, the close association of rivers and structural highs would not be expected to result ...
western and eastern populations of goitered gazelles are separated by zagors mountains as a barrier. bordering iraq, western population has suffered from drastic decline during and after iran-iraq war. presently, there are small numbers of the goitered gazelles left in the region with no clear understanding of their taxonomic status. it has been normally assumed that there should be a differenc...
8 Lophotidae, or crestfishes, is a family of rare deep-sea teleosts characterised by an enlarged 9 horn-like crest on their forehead. They are poorly represented in the fossil record, by only 10 three described taxa. One specimen attributed to Lophotidae has been described from the 11 pelagic fauna of the middle-late Eocene Zagros Basin, Iran. Originally considered as a 12 specimen of the fossi...
