An integrated study including magnetostratigraphy, larger benthic foraminifera and calcareous nannofossil biostratigraphy is presented herein. This work was performed in shallow marine siliciclastics rich foraminifera, around the Ypresian/Lutetian boundary Ésera valley (South-Central Pyrenees). Although content studied interval low, not allowing a precise Y/L to be recognised, taxa found are en...

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...
