the permian deposits in the stratigraphic section of sangsar (located in the eastern alborz), are the best expose in the semnan area. this sequence consists of the doroud (asselian-sakmarian), ruteh (artinskian-murgabian) and nessen (early djulfian) formations. the dorud formation in the studied section with 56 m thickness consists of conglomerate, sandstone and quartzite, which is disconformit...

Biostratigraphic analysis was carried out on KA-1 well, onshore Niger Delta Basin of Nigeria. A total forty (40) ditch cutting samples were collected from the studied section at 30 feet depth intervals with ranging 7590-4800feet. The objectives this study are to determine age and biozonation section. Using simple smear slide method, processed analyzed for nannofossils using a reflected binocula...

a sequence of permian rocks crops out in northwest of khur in central alborz, north of iran. this sequence consists of the dorud (asselian-sakmarian), ruteh (artinskian-murgabian) and nesen (early djulfian) formations. the ruteh and nesen formations in alborz range were deposited in a shallow marine environment of the continental margin in the paleo-tethys. the ruteh formation with a thickness ...

The biostratigraphic distribution of orbitolinids for the Barremian SE France proposed hereafter is calibrated on ammonite biozonation. This work based study eleven sections with associated to macrofossils (ammonites and/or echinids) significant in terms biostratigraphy or overlain levels bearing above macrofossils.

This study's subject is the Padanglampe traverse in Tanete Riaja, Barru Regency, at coordinates 040 30' 25.26" South Latitude and 1190 41' 43.43" East Longitude. sedimentary deposits of The Malawa Formation were this study. study aims to establish formation's age based on presence palynomorph fossils. Vertical measurement with a track thickness approximately 10.5 meters was used for field inves...

A diverse Eocene charophyte flora from a section at Gánt (Vértes Hills), Transdanubian Central Range, north-western Hungary, provides significant new information building on previous studies based only sub-surface data published the mid-twentieth century. This newly acquired material facilitates taxonomic revision and emendation of species Raskyella peckii thereby defines anagenetic lineage thr...
