[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 ...

Assemblages of agglutinated foraminifers ranging from the Aptian to the lower Eocene were studied in the Bile Karpaty unit. One hundred ninety species (43 of them undetermined) were studied taxonomically. The *species Glomospira s traniki and ~ u r r i t e l l e l l a reversa are 'new. Several species of the abyssal "Krashenimikov" fauna (Buzasina inflata, Haplophragmoides decussatus, H . perex...

Extreme coastal inundation associated with the 2004 Indian Ocean and 1945 Makran tsunamigenic-earthquakes highlight the risk of tsunamis to coastlines of the northern Oman Sea. Foraminifera have been used as indicators of paleotsunamis in the past where allochthonous tests, found in low-energy environments such as in coastal lagoons, ponds, and marshes, indicate marine overwash. In this study, ...

SUMMARY Makran subduction zone is very active with ∼38 mm yr−1 convergence rate and has experienced great earthquakes in the past. The latest earthquake of 1945 Mw 8.1 event also triggered a large tsunami led to ∼4000 casualties. However, due incomplete historical seismicity records poor modern instrumentation, mechanism, co-seismic slip characteristics remain unclear. On 2017 February 17, an 6...

In order to assess the potential impact of the geological environment on the health of the population of the Slovak Republic, the geological environment was divided into eight major units: Paleozoic, Crystalline, Carbonatic Mesozoic and basal Paleogene, Carbonatic-silicate Mesozoic and Paleogene, Paleogene Flysch, Neovolcanics, Neogene and Quaternary sediments. Based on these geological units, ...

Turbiditic sandstones from the mid–Late Cretaceous Tianba Flysch sequence are well exposed near Tianba in the north Nieru Valley, southern Tibet, and contain significant amounts of chrome-rich spinels. Microprobe results show that the spinels have a well-developed Fe-Ti trend and have Cr/( ) 0.4–0.65, Mg/( ) 0.3–0.9, and TiO2 2 Cr Al Mg Fe 11%. The occurrence of melt inclusions, and well above ...

Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD...

The Makran subduction zone in northeast and the Sumatra subduction zone (Sunda) in the west have been known as tsunamigenic zones of the Indian Ocean. The 990 km long Makran subduction zone is located offshore of Iran, Pakistan and Oman. Similar to many subduction zones all over the world, the Makran accretionary prism is associated with an imbricate of thrust faults across the zone, which may ...
