Abstract The Gosau Group (Turonian to Ypresian) of the Eastern Alps is a synorogenic wedge-top succession that accumulated in active depocenters an oblique-convergent plate tectonic setting. Due high morphological differentiation by tectonism, displays wide range facies as well marked heteropy and thickness variations over short lateral distances. In area locations Russbach, Hochmoos Formation ...

Cretaceous planktonic foraminifers from Ocean Drilling Program (ODP) Leg 130 consist of two age groups: one dominantly Aptian in age and the other dominantly Maastrichtian. The oldest dated sediments from Ontong Java Plateau occur at ODP Site 807 and are assigned to the early Aptian Globigerinelloides blowi Zone. The assemblage correlates closely with Aptian foraminifers from Deep Sea Drilling ...

granitoid rocks of kaje area, northwest ferdows, with the composition of diorite, monzodiorite, monzonite, monzogranite, syenogranite and granite, with calk-alkaline and high potassium affinities, have trace and rare earth element geochemical characteristics similar to those from subduction zones, belonging to i-type granitoid rocks. most of these rocks are oxidized (magnetite series), while on...

the dehdasht bauxite deposits are located 40 km northeast of dehdasht in kohgilouye and boyer-ahmad province. it is a part of the irano-hymalayan karstic bauxite belt located in the upper part of karstic depressions of santonian-turonian sarvak carbonate formation. the aim of this study is to determine various geneses of pisoliths and prevalent processes in bauxitization. for this purpose, labo...

This study integrates field structural data, petrographic and geochemical (? 18 O, ? 13 C, ? 47 , 87 Sr/ 86 Sr, elemental composition) analyses U–Pb dating of calcite veins cutting the Bóixols-Sant Corneli anticline (Southern Pyrenees) in order to date investigate spatio-temporal relationships between fluid flow fold evolution. E-W trending grew from Late Cretaceous Paleocene at front Bóixols t...

New simplified tectonic models and depositional history of Late Cretaceous rocks are established in a part of Zagros Orogenic Belt that is located in the Northeastern Iraq. These rocks constutes the most important Cretaceous oil reservoir in the Middle East. The dependent tools are petrography, field study and the concept of drowning phases. This concept is relatively new and accurate in explan...

There were three negative seawater strontium-isotope excursions (shifts to lower Sr/Sr values) during the Jurassic and Cretaceous that were of relatively short duration (5-13 my) and showed a relatively quick recovery to pre-excursion Sr/Sr ratios. These excursions occurred in the Pliensbachian-Toarcian (Early Jurassic), Aptian-Albian, and Cenomanian-Santonian (Early and Late Cretaceous respect...
