Middle Miocene depositional evolution of the central Roer Valley Rift system

Correlations between bio- and/or lithostratigraphically analysed boreholes provide new insights on the late-early to early-late Miocene depositional evolution of the central Roer Valley Rift System (RVRS) as part of the southern North Sea Basin. This evolution started with a major regression that occurred in two steps, one during the late...

A large Late Miocene cetotheriid (Cetacea, Mysticeti) from the Netherlands clarifies the status of Tranatocetidae

Cetotheriidae are a group of small baleen whales (Mysticeti) that evolved alongside modern rorquals. They once enjoyed a nearly global distribution, but then largely went extinct during the Plio-Pleistocene. After languishing as a wastebasket taxon for more than a century, the concept of Cetotheriidae is now well established. Nevertheless, the...

Dinoflagellate cyst biostratigraphy of Miocene strata in the Adana Basin, Eastern Mediterreanean, Turkey

The Adana Basin is one of the major Neogene basins situated in SW Turkey with sedimentary successions providing good records of the paleoenvironmental changes that affected the Mediterranean area. Since a detailed biochronostratigraphic framework has not been properly established in the Adana Basin yet, this study will be the first...

Workflow for analysis of compositional data in sedimentary petrology: Provenance changes in sedimentary basins from spatio-temporal variation in heavy-mineral assemblages

The field of provenance analysis has seen a revival in the last decade as quantitative dataacquisition techniques continue to develop. In the 20th century, many heavy-mineral data were collected. These data were mostly used as qualitative indications for stratigraphy and provenance, and not incorporated in a quantitative provenance methodology....

Re-interpreting the biochronology of the La Celia and Los Gargantones mammal sites (Late Miocene, Murcia, Spain)

The biochronological age of the small-mammal populations of Los Gargantones 1, 2 and La Celia (upper Miocene, La Celia sub-basin, Murcia, Spain) is re-interpreted. The presence in Los Gargantones of Occitanomys adroveri, Parapodemus barbarae, Parapodemus cf. gaudryi, Huerzelerimys turoliensis, Atlantoxerus cf. adroveri, and Alilepus evidences a...

Reassessing the biostratigraphy and the paleobathymetry of the gonfolite lombarda group in the como area (Northern Italy)

Calcareous nannofossil and foraminiferal analyses have been carried out on outcrops from the type-area of the Gonfolite Lombarda Group (Como, northern Italy). In these marine fine- to coarse-grained elastics, rapidly accumulating at the southern front of the uprising Alpine range during the Oligo-Miocene, a scarce, but reliable, sequence of...

Shallow lacustrine carbonate microfacies document orbitally paced lake-level history in the Miocene Teruel Basin (North-East Spain)

Results are presented of a detailed carbonate petrographic study of an Upper Miocene lacustrine mixed carbonate-siliciclastic succession in the Teruel Basin (Spain) with the aim of constraining lake-level variability at different stratigraphic scales. Regular alternations of red to green mudstone and lacustrine limestone, termed the 'basic cycle...

Strong climate coupling of terrestrial and marine environments in the Miocene of northwest Europe

A palynological and organic geochemical record from a shallow marine paleoenvironmental setting in SE Netherlands documents the coupled marine and terrestrial climate evolution from the late Burdigalian (∼ 17 Ma) through the early Zanclean (∼ 4.5 Ma). Proxy climate records show several coeval variations in both relative sea surface (deduced from...

Oblique strain partitioning and transpression on an inverted rift: The Castilian Branch of the Iberian Chain

The Iberian Chain is a wide intraplate deformation zone formed by the tectonic inversion during the Pyrenean orogeny of a Permian-Mesozoic basin developed in the eastern part of the Iberian Massif. The N-S convergence between Iberia and Eurasia from the Late Cretaceous to the Lower Miocene times produced significant intraplate deformation. The...

Neogene stratigraphy of the Langenboom locality (Noord-Brabant, the Netherlands)

The locality of Langenboom (eastern Noord-Brabant, the Netherlands), also known as Mill, is famous for its Neogene molluscs, shark teeth, teleost remains, birds and marine mammals. The stratigraphic context of the fossils, which have been collected from sand suppletions, was hitherto poorly understood. Here we report on a section which has been...

Calcareous plankton high resolution bio-magnetostratigraphy for the Langhian of the mediterranean area

High-resolution quantitative and qualitative analyses of the planktonic foraminifer and calcareous nannofossil content have been carried out on three Middle Miocene sections, from the Mediterranean area. Such sections (Cretaccio section, Tremiti Islands, Southern Italy; Moria section, Marche Region, Central Italy; DSDP Site, 372 succession,...

Building stones from a muddy delta: Native natural stone from The Netherlands

Most of the Netherlands a Quaternary delta, local supplies of natural stone suitable for building are rare. These include: Quaternary bog iron ores used in early medieval times (until c. 1200); erratics, deposited in boulder clay during the Saalian ice age in the northern Netherlands and gravel from the river Meuse; Miocene lithified siliceous...

Chronostratigraphy of Late Neogene sediments in the southern North Sea Basin and paleoenvironmental interpretations

A chronostratigraphic framework has been established for Upper Neogene sediments from the northern Netherlands offshore sector, southern North Sea. Data of dinoflagellate cysts, pollen and foraminifers from eight boreholes are integrated and the resulting biostratigraphic events are connected to an additionally retrieved paleomagnetic record....

A southern North Sea Miocene dinoflagellate cyst zonation

An integrated stratigraphical analysis emphasizing organic-walled dinoflagellate cyst (dinocyst) distribution has been carried out on multiple boreholes penetrating the Miocene in the subsurface of the Netherlands (southern North Sea Basin). The bulk of the investigated successions is attributed to the Breda Formation, a regional...
