This paper describes the foraminiferal associations along with presentation of three new agglutinated conical species to construction biozonation framework in Mahallat region central Iran. The stratigraphic distribution benthic foraminifers is used characterize assemblage zones that are ascending order: rotaliids-valvulinids Assemblage Zone, alveolinids-coskinolinids and nummulitids-discocyclin...

The ongoing interest in the complex geology of Dinaric orogen, particular, its immediate, post-orogenic evolution (post-Lutetian), has produced a number tectonic solutions, proposing either extensional stage followed by subsidence, with immense lithospheric thinning resulting regional uplift, or even pure uplift episode(s). unclear Late Oligocene?Miocene forces are often interpreted as intercha...

We present a novel multiproxy data set (bulk and clumped isotopes on gastropod shells variations in ostracod assemblages) of the Hampshire Basin (Southern-England) that sheds light connection between North Sea Atlantic Ocean through English Channel during deposition Barton clay formation (latest Lutetian—Bartonian, middle Eocene; ∼41–40 Ma). During this time period, operated as gateway warmer c...
