  V Notch Weir
The ventilated air pocket formed under the nappe insuresthat atmospheric pressure is present to all sides of the nappe.
With atmospheric pressure on all sides the nappe is properly shaped for maximum accuracy.
The pool formed upstream of a weir plate is not self scouring, to easily flush any sediment that may accumulate upstream of the weir an optional flushing port at the bottom of the weir plate is available.

According to Nappe, before he left for Iraq he approached Lawlor when the town disputed his ability to take a leave of absence for what the town perceived to be a job in the private sector.
According to Nappe, Gallo was aware of the process the whole time, during which time Gallo signed off on paperwork and spoke on the phone on Nappe's behalf.
According to Nappe, it wasn't until he was accepted that he heard any dissent, which is prompting him to wonder whether or not the town's refusal to grant him a leave of absence and to now rehire him wasn't based on personal matters.

Nappe was denied a request for a leave of absence by from the force last September by the Police Department Commission.
At the time Nappe's departure, his ability to return to the force after his year-long freelance position was concluded was contested by the Police commission, Police Chief Leonard Gallo, and Mayor Joseph Maturo.
Among their concerns were the fact that Nappe was leaving the force to take a job for what they perceived to be in the private sector.

Nappe, with arms covered in American flag tattoos bearing the date "9/11/01" and "Born Free," wants to be one of them.
Nappe said Police Chief Leonard Gallo expressed concerns about overtime costs and manpower issues, saying he did not want to be down too many officers.
Nappe was previously denied a similar opportunity years ago when he was accepted for a civilian-policing mission in Kosovo.

 Underplating-related finite-strain patterns in the Gran Paradiso massif, Western Alps, Italy: heterogeneous ductile ...   (Site not responding. Last check: 2007-10-16)
We conclude that nappe stacking occurred early during subduction probably by brittle imbrication and that ductile strain was superimposed on and modified the nappe structure during high-pressure underplating in the Alpine subduction zone.
Common wisdom is that the bases of nappes are high-strain zones and that therefore the accumulation of large finite strains and nappe emplacement are intimately related.
It is concluded that nappe stacking during high-pressure metamorphism in the Alpine subduction zone was not by simple shear alone and involved a component of pure shear, which is responsible for the subhorizontal foliation within the nappes.

 INTRODUCTION to the PREALPES GEOLOGY
The Préalpes are formed by several allochthonous tectonic klippen resting on the N and NW central European alpine foreland, in front of the Helvetic nappes and the external crystalline basements of the Alps (Schardt 1898; Jeannet 1922; Trümpy 1960; Badoux and Mercanton 1962; Caron 1973; Plancherel 1979; fig.1).
Elsewhere the sole of the Préalpes is in contact with the underlying units (the Helvetic nappes in the S and the Subalpine Molasse and flysch to the N) by means of the "Ultrahelvetics" (Badoux 1963; Homewood 1977; Jeanbourquin 1991, 1992, Jeanbourquin and Goy-Eggenberger 1991; Jeanbourquin et al.
The Préalpes Médianes nappe was detached from its basement and underwent thin-skinned tectonics during the Alpine orogeny.

 New Haven Register - Ex-cop testifies in fight for job
Nappe requested reinstatement twice — each time after the General Assembly passed a law guaranteeing that police officers in his position would be rehired, Cofrancesco said.
Nappe responded that the U.N. was involved at one point, but left Baghdad after its headquarters was bombed.
While he retired after the board denied his request for a leave, he never drew from his retirement pension, she said — and Nappe later testified that he considered "retiring" and "resigning" to be the same thing.

The Jurassic stratigraphy of the Breccia Nappe was defined lithologically by LUGEON (1896).
The Breccia Nappe, today overlying the internal parts of the Préalpes Médianes, represents mainly syn-rift deposits from the northern margin of the Piemontais ocean whereas the Préalpes Médianes nappe originates from the Subbriançonnais and Briançonnais realms which were separated from the Pre-Piemontais domain by the inner Briançonnais scarp shoulder (Acceglio zone).
The correlation of the post-Jurassic series of the Breccia nappe between the Romandes- and Chablais regions, in addition to the sedimentologic and stratigraphic data, permits the construction of a model to explain the geodynamic evolution of the Breccia nappe since the Early Cretaceous.

 Geodynamic evolution of the Carnic Alps: Plate tectonic interpretation of the southern margin of the European Variscides
The nappe contact between Fleons nappe and Cellon-Kellerwand nappe is marked by a klippen zone, where remnants of the higher-metamorphic Fleons nappe rest on top of the lower-metamorphic Cellon-Kellerwand nappe.
The nappe contact between the Cellon-Kellerwand nappe and the Hochwipfel nappe is marked by broad mylonitic thrust planes and duplex structures.
During the Silurian and Devonian, a widespread facies differentiation in the Carnic Alps is typical for extensional tectonism and horst-and-graben structures on continental crust.

 Chapter4: D2: Nyimaling - Tsarap Nappe
In the studied area, the complete transition from ductile to brittle deformation associated with the southwestward thrusting of the Tethys Himalaya can be observed from the base to the top of the nappe.
Ductile deformation is restricted to the transition zone between the HHCS and the TH and is only preserved in the upper part of this zone, where the structures related to this deformation have not been overprinted by the strong penetrative deformation related to extensional movements along the ZSZ.
Thus, although the normal stratigraphic succession between the Carboniferous Lipak and Permian Po Formations is nearly always preserved, this gypseous horizon certainly accommodated much of the compressive tectonics at the front of the Nyimaling Tsarap nappe.

 ABSTRACT   (Site not responding. Last check: 2007-10-16)
A portion of the accretion channel was thus finally emplaced, jointly with several lower Pennine units containing high pressure relics (Adula nappe, Cima Lunga complex, Monte Rosa nappe), as the uppermost unit of the Central Alpine nappe stack, the Southern Steep Belt.
P-T data obtained for garnet amphibolites related to the Simano nappe show a coherent and simple P-T path, which indicates a monometamorphic evolution of the metabasites, in contrast with the polymetamorphic basement of the Simano nappe (Chollet, 2000) and the metamorphic evolution established in the Adula nappe and Cima Lunga complex.
This indicates that after nappe stacking and during obduction those units share the same common history : on its way back to the surface the Adula nappe met the Simano nappe and accompanied its rapid exhumation to the surface.

 EXHUMATION AND PROBABLE EXTENSION IN THE HELGELAND NAPPE COMPLEX, UPPERMOST ALLOCHTHON, CENTRAL NORWAY   (Site not responding. Last check: 2007-10-16)
Within the Velfjord-Tosen area, the HNC can be divided into lower and upper nappes consisting of Proterozoic partially migmatitic gneiss, calc-silicate, and marble, and a middle nappe consisting of Ordovician ophiolite sequences and unconformably overlying medium- to low-grade metasandstones, metaconglomerates, and metacalcareous rocks.
Amalgamation of the HCN occurred prior to emplacement of the 448 Ma Andalshatten pluton that is interpreted to truncate thrust faults associated with nappe formation.
New mapping along the boundary between the lower and middle nappes in the area has recognized the presence of asymmetric folds and outcrop-scale asymmetric structures (S/C, porphyroclasts) that suggest top to the southeast sense of shear along shallowly east-dipping shear surfaces.

 New Haven Register - Rell signs bill on peacekeepers
But the legislation’s originator said he believes the town will continue to refuse to give Nappe his job back, and is gearing up for a legal battle in which he believes the town will argue that the legislation is unconstitutional.
Nappe said he believes the town is trying to string the case out in hopes that he runs out of money — which he said may well happen.
Nappe retired from his 19-year job as an East Haven cop in early 2004 after the Board of Police Commissioners refused to grant him a one-year leave of absence to take a job training Iraqi police officers for DynCorp, a private company working on contract for the U.S. State Department.

The North Qinling nappe system was formed by decoupling, thrusting and stacking of upper crustal sheets of the North Qinling along a brittle-ductile transition zone.
It is composed of the Luanchuan nappe, Waxuezi nappe, Erlangping nappe and Zhuxia nappe.
The subduction of the Yangtze block towards the North China block during the Palaeozoic had not caused the land in Qinling to be uplifted and become mountains.

Neotectonic Activity in the Chamba Nappe of the Himachal Himalaya
A study of the possible correlation between kink-band, jointing and drainage patterns in the Chamba nappe (Himachal Himalaya) shows a correspondence between the valley trends and the joints, indicating a neotectonic control of both features.
However, no correlation exists between the Precambrian to Upper Paleozoic conjugate kink-bands and the present joint/valley orientations, showing that there was a fundamental change in the tectonic pattern between the Upper Palaeozoic and the recent ongoing crustal adjustment in the Himachal Himalaya.

Consequently, the uppermost Chaudière Nappe comprises the oldest and farthest-travelled rocks, whereas the lowest and most northwestward structural unit, the Québec Promontory Nappe, is made up of the most proximal and least-transported strata.
Fracture sets and veins were studied within the Québec Promontory Nappe in order to characterize the nature of fluids and timing of their migration within the nappe.
We interpret the stratigraphic and structural relationships in the Québec Promontory Nappe as reflecting the development of an extensional basin on the outer shelf in the immediate foreland of advancing nappes.

 VERY LOW-GRADE METAMORPHISM in the PREALPES
The uppermost Nappe Supérieure and the upper part of the Breccia nappe are diagenetic, and metamorphic grade increases towards the lower part of the Breccia Nappe.
Thus metamorphism in the Préalpes Médianes, Breccia Nappe and Nappe Supérieure is transported.
The burial metamorphism of the Préalpes Médianes by the superposition of the Nappe Supérieure and the Breccia nappe is corroborated by syn-metamorphic internal deformation mechanisms associated with the arrival of the latter nappes (Mosar 1989, 1991).

The nappe pile in the Monte Rosa region represents the Eo- to Oligocene high-grade accretionary wedge of the Western Alpine arc.
The restoration of the remaining D3 thrusts and folds results in a triangle structure, in which the pile of continental nappes is wedged between the ophiolitic units.
Since the Monte Rosa nappe and the Stockhorn-Portjengrat unit share a similar high-grade metamorphic evolution, and since the Portjengrat unit and the Furgg zone were intruded by basalts derived from the same magma source, the Monte Rosa nappe and the Stockhorn-Portjengrat unit were considered as a previously continuous tectonic unit.

In the mapping area, the Tsaté Nappe can be divided in two units with different dominant lithologies, a different pre-greenschist-facies history, different conditions during greenschist-facies metamorphism, and a different structural inventary.
A division of the Tsaté Nappe in two units dominated by greenschists or calcschists, respectively, is reported by Vannay and Alleman (1990) from the E' side of the Valtournanche valley.
The Tsaté Nappe (Combin Zone) rocks were mostly considered to have undergone only greenschist-facies to greenschist-blueschist-transitional-facies metamorphism with scarce glauc as the only indicator of elevated pressures (Ballevre et al., 1986).

The Suretta nappe has been chosen for two main reasons: the occurrence of late Variscan granites deformed only during Alpine tectonics and the occurrence of continuous outcrops from the top to the bottom of the nappe.
The study of shear zone distribution and strain partitioning at the nappe scale is a tool to understand the geometry and the kinematics of deformations in polymetamorphic basement.
To focus on strain partitioning at the nappe scale, the shear zone patterns have been analysed in the Permian Roffna metagranite which occurs from the bottom to the top of the nappe.

The Naukluft Nappe Complex (NNC) forms a far-traveled fold and thrust belt klippe of the Panafrican Damara Belt in central Namibia.
Field observations suggest that several pulses of fluid-induced brittle deformation overprinted, in a cyclic fashion, ductile structures formed during the emplacement of the nappe edifice.
A “fault valve” behavior is suggested for the basal detachment of the NNC, with bulk shortening being accommodated by incremental slip during a history of combined viscous and frictional flow.
