[1] In the Shiquanhe area of far-western Tibet, midCretaceous strata lie unconformable on ophiolitic melange and Jurassic flysch associated with the Bangong-Nujiang suture zone. On the basis of our mapping and geochronologic studies, we suggest that these Cretaceous strata were shortened by >57% over a north south distance of 50 km during Late Cretaceousearly Tertiary time. The Late Cretaceous ...

The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...

The northern Oman margin is a key area for understanding the emplacement of Semail Ophiolite and obduction processes in general. This study uses grid 2D-multichannel seismic lines tied to well data characterize offshore domain reappraises post-obduction history margin. West Muscat, Sohar basin, late Cretaceous Paleogene tectonic mega-sequence records syn- late-obduction stages deposition erosio...

[1] Uppermost Cretaceous to Eocene marine sedimentary sequences occur both to the south and north of the Yarlung Zangbo suture in south central Tibet. They consist of Indian-margin strata of the northern Tethyan Himalaya and Asian-margin strata of the Gangdese forearc. Both assemblages are characterized by major changes in depositional environment and sedimentary provenance at 65 Ma and an appe...

A moderate (M ~5) earthquake struck the northeastern United Arab Emirates (UAE) and northern Oman on March 11, 2002. The event was felt over a wide area of the northern Emirates and was accompanied by smaller (felt) events before and after the March 11 main shock. The event was large enough to be detected and located by global networks at teleseismic distances. We estimated focal mechanism and ...

The Zhob ophiolite is divided into Ali Khanzai, Omzha, and Naweoba blocks. geology comprises various lithological units including basalt–chert hyaloclastite mudstone units. consist of thick lava pelagic sediments. On the basis petrology geochemistry, lavas unit can be tholeiitic basalt, trachybasalt, basaltic andesite dacite, that more alkaline foidite, picrobasalt, tephrite-basanite. rocks hav...
