The upper nappe, which constitutes the Zone Houillere and is referred to as the middle Pennine, is the most external of the Saint Bernard nappe complex.

The succession comprises beds dated by plants as Namurian and Westphalian A unconformably overlain by the Granon conglomerates of Stephanian age. Upper Westphalian. After Eagar, in Higgs () the fresh-water bivalve assemblages in Cycle 3 are suggested to be middle to upper Namurian age.

Figure 3: Sedimentary profiles of the fining-upward sequences of the cycles 7 and 8. The first two profiles were measured SSW of Abbotsham Cliff, the third was measured at. The differences in thickness result from gradual wedging out of the deposits to the north-west, differences in advancement of erosion of the Westphalian and erosion from the the Namurian times (Fig.

Marine, fresh-water and. brackish fossils derived from 13 boreholes evidence,the Upper Visean, Lower and Upper Namurian and Westphalian A and B. There are: Cracow Sandstone Series (Westphalian B-D), Upper Silesian Sandstone Series (Namurian B-C), Siltstone Series (Westphalian A, lower Westphalian B) and Paralic Series (Namurian A).

Carboniferous aquifers represented by sandstones, partly siltstones, have a thickness ranging from to more than several dozen meters. Its age, as determined almost entirely by non-marine and restricted marine bivalves, is Late Namurian, late Rlc to Early Westphalian, early Communis Zone.

The lowest m of the succession, including the Westward HoI Formation with turbidites, is largely unfossiliferous and may be of middle to Late Namurian by: 7. This volume summarizes the results of a survey of British Upper Carboniferous sites, undertaken between and as part of the Geological Conservation Review (GCR).

The GCR was the first attempt to assess the scientific significance of all Britain's geological sites and has proved a landmark in the development of a coherent geological conservation strategy in this country.

Freshwater is a stunning novel, one that I dove into and couldn't surface out of for a while. It's like a pool of dark water that you don't really even want to get out of. And I was sad when the book finished - despite it being quite a violent and shaking experience.4/5(K). The freshwater fauna occurring in the lower and upper part of the horizon is represented mainly by the bivalves Carbonicola, Naiadites and Anthracosia.

Ostracod s, annelids (Spirorbis) and fish scales are also frequent (Musiał and Tabor,Musiał and Tabor,Musiał and Tabor,Musiał et al., ). The Upper Namurian–Westphalian successions occupy a wide geographic domain of approximately km 2 in the central part of the Cantabrian Zone composed from W to E, of relevant coalfields such as Teverga, San Emiliano, Quirós, Central Asturian and La Marea–Coballes.

All these coalfields are separated from one another by major thrust units. Late Palaeozoic glaciation of Gondwana affected ecosystems and caused provincialism in the earth’s biota. Periglacial seas favored the origin of endemic genera and species, and remarkable differences exist with faunas of the Palaeoequatorial realm.

Carboniferous glacimarine deposits are almost everywhere associated with theLevipustula levis “cold” fauna. These bio- and lithofacies are. The application of sequence stratigraphy to Upper Carboniferous fluvio-deltaic strata of the onshore UK and Ireland: implications for the southern North Sea.

An Amazon Best Book of February Freshwater is a mesmerizing and poetic novel that cracks open notions of self-control, mental illness, and love.

The Upper Carboniferous (Pennsylvanian) is distributed in 5 separate main regions. 1) The Culm Trough in SW England was a shallow marine to lacustrine basin that was progressively filled during the Namurian and Westphalian, in part coincidental with basin inversion and tectonic deformation.

2) The Kent Coalfield, known only through boreholes. Invasion of the Pennine late‐Namurian delta took place when marine bivalves pushed upward, thereby avoiding sedimentation from delta lobes moving seaward relatively swiftly.

and species of the genus were probably epifaunal or shallowly infaunal active burrowers on soft bottoms in Westphalian upper A and B a fact which again suggests.

In Europe the Lower Carboniferous sub-system is known as the Dinantian, comprising the Tournaisian and Visean Series, dated at Ma, and the Upper Carboniferous sub-system is known as the Silesian, comprising the Namurian, Westphalian, and Stephanian Series, dated at Ma.

The Silesian is roughly contemporaneous with the. = fresh water, E = euryhaline) and relative sea level curve to the right. Westphalian B and Westphalian A strata are respectively shown in the left and right litholog and are separated by the Quaregnon marine band, which is situated at a depth of meters (adapted from Paproth et al.
