Oxygen and carbon isotope ratios of benthic foraminifers were measured on the continuous middle to lower bathyal sedimentary sequence dated from the upper Maestrichtian to lower Eocene which was recovered at Site 752 in the eastern Indian Ocean. The changes in the carbon isotope values can be correlated with the faunal changes of the benthic foraminifers.

Upper abyssal to lower bathyal benthic foraminifers from ODP Sites 689 (present water depth 2080 m) and 690 (present water depth 2941 m) on Maud Rise (eastern Weddell Sea, Antarctica) are reliable indicators of Maestrichtian through Neogene changes in the deep-water characteristics at high southern latitudes. Benthic foraminiferal faunas were divided into eight assemblages, with periods of faun...

It is the first time that biostratigraphic zonations of calcareous nannoplankton from Maestrichtian to Lower Tertiary deposits of Iran are reported. The required samples from the north-eastem and western parts of the country were selected from the stocks of the National Iranian Oil Company. Taxonomic descriptions were not the main objectives, although a new species and genus are apparently ...

bibi maryam granitoid body with about 5 km2 has intruded into ophiolite mélange complex in sistan suture zone, in east of iran. thermal effects of this body on the host rocks show that this activity occurred after emplacement of ophiolite mélange. this intrusive body with general northwest – southeast trend is mainly tonalite-quartz diorite but there is a minor unit as dykes of granodiorite in ...

The Almopia Speleopark caves are located at the basin in northern Greece, foothill of Voras Mountain, and formed Maestrichtian limestones Pelagonian zone. They studied on basis their meso- micro-scale morphology as well horizontal pattern, order to investigate character forming aquifer. Emphasis is given morphological description Loutra Almopias Cave. Cave dominated by presence cupolas, rock br...

between the lower and upper cretaceous there were some diastrophic movements, belonging to the austrain phase. these movements, which can be traced in many parts of north and central iran, caused extensive precenomanian erosion. even in southwest iran a wide spread discontinuity is reported at the base of the kazhdumi formation, which is possibly related to these movements. in the kopet - dagh ...

-THE Sierra Leone Rise, located in the east equatorial Atlantic. forms a discontinuous chain of seamounts as shallow as 2 km extending with a general NE-SW trend from near the Sierra Leone Coast of Africa, to the St Paul fracture zone near the Mid-Atlantic Ridge (Fig. 1). The origin of this feature has remained a topic of discussion. Sheridan et al.' have hypothesised that the Sierra Leone Rise...
