Facies Change

Abstract The rocks of the Santa Croce lake region belong to the calcareous southern Alps formed from a lower Triassic sequence. The sediments show a facies change between the reefal series of the Friuli zone to the east and the deep water Belluno zone to the west. The entirely marine series may be divided into two groups: the Liassic to Oligocene beds characterized by the absence of terrigenous sediments with thick limestones; and Eocene to Oligocene terrigenous flysch deposits. The area is part of the Venetian Prealps with east to west structural orientation.

Abstract The stratigraphic sequence of the Garda lake region contains varied facies of marine Triassic to Lutetian rocks. The zone borders the Tridentine zone to the east and the Lombardian depression on the west. The lower Liassic is a thick shallow water facies decreasing in thickness and displaying deep water characteristics in the upper Liassic. The Cretaceous is a white limestone series that progressively becomes more terrigenous as it grades upward to the Eocene.

Marly Limestone

Abstract The Neocomian (lower Cretaceous) of the lower Verdon region (Basses-Alpes, southern France) represents a transition facies between deep-water marine deposits to the northwest and continental deposits to the southeast. The facies change between the marly limestone series of the flexure zone to the west and the white limestone series of the platform to the southeast can be traced. Fluctuations of the ancient shoreline resulted in alternations of bioclastic marine limestones and lacustrine sediments.

Abstract The stratigraphic sequence of the Trescore-Balneario region in the southern Alps is entirely marine consisting of thick concordant deposits from the Triassic to the upper Cretaceous. They are discordantly overlain by Pliocene beds. Liassic rocks in the sequence represent a shallow water facies whereas the Dogger, Malm, and Neocomian reflect deposition in deep water. The remainder of the Cretaceous is a flysch sequence derived from a source to the west. The Pliocene represents a transgressive marine sequence of red sandstones and argillites containing fragments of pelecypods and gastropods.

Inflowing Water

The renewal of east Atlantic deep water and its large-scale circulation and mixing have been studied in observed distributions of temperature, silicate, ΣCO2, and 14C. 14C variations in northeast Atlantic deep water below 3500m depth are small. Δ14C values range from − 100‰ to −125‰. 14C bottom water concentrations decrease from Δ14C =−117‰ in the Sierra Leone Basin to Δ14C = − 123‰ in the Iberian Basin and are consistent with a mean northward bottom water flow. The characteristic of the water that flows from the west Atlantic through the Romanche Trench into the east Atlantic was determined by inspection of θ/Δ14C and θ/SiO2 diagrams. A mean potential temperature of θ = 1.50 ± .05°C was found for the inflowing water. A multi-box model including circulation, mixing, and chemical source terms in the deep water has been formulated. Linear programing and least-squares techniques have been used to obtain the transport and source parameters of the model from the observed tracer fields. Model calculations reveal an inflow through the Romanche Trench from the west Atlantic, which predominates over any other inflow, of (5 ± 2) Sv (potential temperature 1.50°C), a convective turnover of (150 ± 50) years and a vertical apparent diffusivity of (4 ± 1) cm2/s. Chemical source terms are in the expected ranges.

Summary The first record of Andrena florivaga Eversmann, 1852 is reported from Poland on the basis of specimens collected in the Kampinos National Park (Mazovian Lowland). Diagnosis, data on localities, biology, and general distribution of the species are provided. One female and five males were caught on a mowed fresh meadow and fallow fields with the use of water pan-traps (Moericke traps), during the 2003 - 2004 time period. The main morphological characteristics distinguishing Andrena florivaga from the very similar Andrena dorsalis Brullé, 1832 species and from the other species of the subgenus Lepidandrena are: in the case of females - the width of facial foveae and colouration of legs, and in the case of males - the length of the first flagellar segment, colouration of clypeus, and pubescence of gonostyles. Andrena florivaga can be found from France in the west, to Central Siberia (Baikal lake region) in the east, and Turkey in the south. Poland is the northernmost locality of the species.

Contourite Drifts

The middle Ordovician of Pingliang area on the west margin of North-China platform is represented by a succession of deep-water sediments in which contourites are well-developed. Contour current deposits are well-developed. The contourites can be classified into:calcarenitic contourite, calcisiltitic contourite and calcilutitic contourite. Three typical contourite successions are recognized: complete contourite succession, incomplete contourite succession and contourite successions consisting only of calcarenitic contourites. According to the palaeocorrent and the palaeogeographic format analyse,carbonate contourite drift in the study area is unfolded crossing northwest-southeast, forwarding from southeast to northwest along the slope, and compared with other contourite drifts, it has some characteristics of coarser-grained sediment, thicker individual layers, and highly developed calcarenitic contourites and so on.
