Abstract During the Tertiary evolution of Western Mediterranean subduction system, a migrating foreland basin system developed between Maghrebian orogenic belt and adjacent African Craton. However, comprehensive reconstruction systems Rif Chain is still missing. By integrating field observations with quantitative biostratigraphic data from calcareous nannofossil assemblages, sandstone compositi...
Hesaruiyeh granitoid is located about 85 Km east of Zahedan city, in the Sistan suture zone. This granitoid occurs as small stocks in Cretaceous ophiolite melange and Eocene Flysch. This granitoid is composed of granite, granodiorite and diorite. Granite and granodiorite consist mainly of quartz, plagioclase, orthoclase, biotite and hornblende and diorite is composed of plagioclase and hornblen...
New geochronological data and published structural and stratigraphic data show that two distinctly different ophiolitic assemblages formed in general proximity to one another at nearly the same time and were subsequently imbricated along a regional thrust zone. The Josephine ophiolite constitutes a complete oceanic crust and upper mantle sequence which lies within the western Jurassic belt of t...
The Slano Blato landslide is more than 1290 m long, 60 to 200 m wide and 3 to 11 m deep with a volume of about 700 000 m3. It is located in the Eocene flysch region of western Slovenia with a limestone overthrust in the direct vicinity, above the landslide. The landslide moves mainly as a viscous earth flow with occurrences of rapid mud flows. In dry periods or in freezing conditions it behaves...
[1] Paleomagnetic data from the Internal Sierras unravel the kinematic relationship between basement (Guarga, Gavarnie, Bielsa) and cover thrusts (LarraMonte Perdido). The new data come from an area of 100 km along strike and 5–15 km across strike of the southwestern Pyrenees. The area covers a variety of structural positions that range from cover to basement thrusts. From 84 sites located in U...
