Topic: Kimmeridgian


In the News (Sun 15 Nov 09)

  
 [No title]
The general drop in paleotemperatures observed from Early to Late Kimmeridgian corresponds to a decrease in the generic diversity of benthos.
The maximum paleotemperatures in the Early Kimmeridgian coincide with the predominance of the thermophile family of bivalves Trigoniidae.
A drastical drop in temperature in the Late Kimmeridgian was recorded above and below a bed with the least diversified benthos.Throughout the Kimmeridgian, the composition of benthic communities was steadily dominated by suspension feeders.

  Kimmeridgian
The vineyards of Menetou-Salon and Sancerre, well known for their most characteristic type of vine, the Sauvignon, prefer before all, the marly limestone grounds of the Kimmeridgian stage.
At the base of the formation, a level with green lumachellic conglomerate separates the "Marls from St Doulchard" and the "Limestones of Buzançais" ( lower Kimmeridgian, Cymodoce zone p.p.).
Than follows an alternation of gray marls, becoming fl in the depth, and fine limestone of clear gray to dark gray color, sometimes covered with a beige patina.

The individuality of the Michel REDDE wines is essentially due to the soil exposure and the composition of the two main soils that make up the vineyards that are situated at the heart of the appellation.
One half of the estate, facing south, south-west, is situated on Kimmeridgian marl in the commune of Pouilly-sur-Loire.
Kimmeridgian marl can be easily identified by the presence of numerous shells of oyster and comma-shaped fossils both of which are particularly abundant in the " Cornets " and " Griottes " plots.

 diplodocoidea
This animal was named from a diplodocid hindlimb with at least four clawed toes, unusual because diplodocids usually have only three.
It was found from a locality that was either Kimmeridgian (LJ) or late Maastrichtian (LK) in age.
Due to the primitive nature of the foot, and the fact that no diplodocids have been found anywhere else in the LK of North America, the older age is favored here.

Kimmeridgian and Lower Tithonian calcareous and siliciclastic sediments represent basinal and slope, shallow marine, and terrestrial environments.
During the latest Oxfordian-early Kimmeridgian, a sudden relative sea-level rise drowned or partially drowned the earlier buildups, and this was quickly followed by a major influx of siliciclastic sediments.
It accumulated over 2.5 km of Kimmeridgian siliciclastic sediments, and is bounded to the east by the Vila Franca de Xira fault zone.

Abstract: Three marly reefal associations from the Kimmeridgian of Portugal (Alcobaça, Serra Isabel) and southwestern Germany (Faulenhau), which share a high proportion of coralline sponges as a main unifying element, were studied in a comparative manner.
The two Portuguese associations are dominated by corals and coralline sponges (Alcobaça), and by crinoids and corals (Serra Isabel), respectively.

 Facies, Stratigraphy and Paleogeographic Analysis of Upper? Kimmeridgian to Upper Portlandian Sediments in the Environs ...
Late Upper Kimmeridgian to final Portlandian sediments in the environs of Arruda dos Vinhos, Portugal, consist of deltaic siliciclastics, the Sobral formation, and lagoonal deposits, the limestone-marl sequence of the »Pteroceriano« formation and the limestone-marl-sandstone sequence of the Freixial formation.
The superimposed, uppermost Kimmeridgian to early Lower Portlandian »Pteroceriano« formation is mainly restricted to this Arruda depo-center, only extending further north and west at its base, probably coinciding with the peak in global eustatic sea level highstand.
The formation's lower part is mainly composed of low energetic marls and limestones, among which the nodufar Arcomytilus limestones deserve special interest, since they indicate occasional very rapid deposition of lime mud followed by morphological adaptions of the bivalve Arcomytilus morrisi.

Support is given to the division of the Lower Kimmeridgian into the Pictonia involuta and Rasenia evoluta Zones adopted for West Siberia.
Specific taxonomic differentiation of the Kimmeridgian families and genera of ammonites in the Northern Hemisphere permits recognition of two zoogeographic realms, circumpolar Arctic and Boreal-Atlantic, which taken together form the Panboreal Superrealm.
In the Early Kimmeridgian, this province was part of the Arctic Realm, whereas in the Late Kimmeridgian it belonged to the Boreal-Atlantic Realm.

For growers here, Kimmeridgian applies to the marl facies which suits Chardonnay so well: layers sometimes almost 80m deep, of marl interspersed with small benches of limestone, which help to create the gentle rolling hills of Chablis.
Much expert study has finally produced the 1978 Decree modifying the specification for this AOC and redefining the appellation areas, except those of the grands crus.
The Kimmeridgian specification is being replaced by a group of criteria applying to high-quality wine, which cover soil, subsoil, relief, aspect and suitability for cultivation.

The requieniid rudist species ‘Matheronia’ salevensis FAVRE, first described from the Tithonian of Mont Saleve, eastern France, is transferred to the genus Hypelasma PAQUIER, which is distinguished from Matheronia by possession of a posterior myophoral ledge in the left (attached) valve.

The Kimmeridgian strata succeed Oxfordian Age rocks (see OXF) and is succeeded itself, in the GCR, by the Portlandian to Berriasian strata (see PTL-BER).
After the Kimmeridgian there was a major fall in global sea level in Portlandian times, which led to re-emergence of certain land areas.
In addition, in Kimmeridgian times there were pterosaurs, ichthyosoars and turtles in the Kimmeridgian Age (trhe British Kimmeridge Cklay producing some of the best-preserved Late Jurassic marine reptiles ever found).

Growth geometry and porosity of early Kimmeridgian reefs formed in the north-western Iberian Basin record a complex interaction between tectonic and eustatic effects during sedimentation followed by a history of prolonged diagenetic modification.
In the northern region, local tectonism resulted in an off-lapping complex of reefs whereas the morphology of reefs of the southern region was dominated by vertical accretion and seaward progradation.
In the southernmost sector, where reef framework facies dominated, the majority of porosity was generated by the dissolution of aragonitic corals during subaerial exposure and alteration with meteoric waters.

In this paper the parastratigraphic subdivision of the NW-German Kimmeridge and especially the delimitation between the German Ober-Oxford* (Korallenoolith) and Unter-Kimmeridge* is revised on the basis of ostracode faunas.
Consequently, the upper parts of the German Korallenoolith have either to be assigned to the Kimmeridgian, or a stratigraphical break has to be acknowledged at the top of the Korallenoolith comprising at least two ammonite zones.
In this context it should be mentioned that "Kimmeridgian" in this paper comprises the zone sequence between Baylei zone and Autissiodorensis zone and is in this sense equivalent only to the "Lower Kimmeridgian" of English stratigraphers.

The knowledge of the exact vertical extension of the Ataxioceratinae faunas on these sections allows to work out a detailed zonation of the uppermost Oxfordian and lower Kimmeridgian, which is also true for the whole submediterranean region (beyond the usual limits of the only zone).
The problem concerning the limit between Oxfordian and Kimmeridgian and its possible synchronism in the submediterranean and subboreal region is here raised.
The Crussolian is again considered as the submediterranean equivalent to the Kimmeridgian.

The facies of the deposited calcareous shallow water platform sediments of the Reuchenette Formation (Kimmeridgian sensu gallico) in Northwestern Switzerland is mainly controlled by relative sea level fluctuations.
Sedimentological investigations and analysis of lithology of several sections from the northern (Ajoie) and the southern Jura mountains (region of Biel) reveal, that the Kimmeridgian deposits can be subdivided into sedimentary cycles of different scales.
Deposits of the Lower Kimmeridgian indicate depositional environments shifting from subtidal conditions in semi-restricted lagoons to low energy conditions in tidal flats.

Revisiting amorphous organic matter in Kimmeridgian laminites: what is the role of the vulcanization process in the amorphization of organic matter?
Kimmeridgian bituminous laminites from Orbagnoux (France) contain abundant amorphous organic matter (AOM).
Previous studies have shown that the vulcanization pathway was the dominant preservation mechanism of AOM in these laminites, and led to its structureless aspect (a process called amorphization) at the nanoscale.
