Report ESPON ACTAREA:Thinking and planning in areas of territorial cooperation Implementation of the Swiss Spatial Strategy and Atlas of Swiss Action Areas CHILLA, Tobias, et al. & ESPON EGTC Abstract Combining diverse material gathered from the analysis of the Swiss policy context and the exploration of the 12 Swiss AAs, this separate report is aimed at providing a comprehensive view on the Swiss experience with soft territorial cooperation. Chapter 2 introduces the policy context relevant for the analysis of the Swiss AAs. Chapter 3 presents the different supra-regional collaborations taking place on Action Area level, framing them in their territorial context, and proposes an analytical grid to analysing them. Chapter 4 synthetises results obtained from the analysis of the 12 Swiss AAs, classifying them based on their maturity of cooperation and summarises policy options as expressed by field actors. Chapter 5 is set up as an Atlas, offering in-depth presentation of the 12 Swiss AAs. Reference CHILLA, Tobias, et al. & ESPON EGTC.

Transalpine Pass Routes in the Swiss Central Alps and the Strategic Use of Topographic Resources
Preistoria Alpina, 42 (2007): 109-118 ISSN 09-0157 © Museo Tridentino di Scienze Naturali, Trento 2007 Transalpine pass routes in the Swiss Central Alps and the strategic use of topographic resources Philippe DELLA CASA Department of Pre-/Protohistory, University of Zurich, Karl-Schmid-Str. ���������������������������4, 8006 Zurich, Switzerland E-mail: [email protected] SUMMARY - Transalpine pass routes in the Swiss Central Alps and the strategic use of topographic resources - Using examples from the San Bernardino and the St. Gotthard passes in the Swiss Central Alps, this paper discusses how the existence of transalpine high altitude pass routes can be inferred, even though there is a lack physical evidence, from specific Bronze and Iron Age settlement patterns in access valleys. Particular attention is given to the effect of topography within the territorial and economic organizational area on transalpine tracks and traffic routes. A set of recurring patterns, such as strategic position, natural and/or artificial protection, presence of “foreign” materials, can help identifying (settlement) sites with particular functions as regards traffic and trade within the systems of territorial organization. Moreover, the paper also addresses socio-dynamic issues of the problem of transalpine pass routes. RIASSUNTO - Passi transalpini nelle Alpi Centrali Svizzere e uso strategico di risorse topografiche -Usando esempi dal Passo di San Bernardino e dal Passo del San Gottardo nelle Alpi Centrali Svizzere, il presente contributo discute come l’esistenza di vie di transito transalpine d’alta quota possa essere dedotta, anche mancando evidenze fisiche, da specifici modelli insediativi dell’età del Bronzo e del Ferro presenti nelle valli di accesso. -

North Sea], or from E. toW. as [North Sea . w. Adriatic]. The Basic Watershed, which also answers to the title [Po ~ w. Rhine], is short arid for purposes of practical convenience scarcely requires subdivision, but the distinction between the Aar basin (actually Reuss, and Limmat) and that of the Rhine itself, is of too great significance to be overlooked, to say nothing of the magnitude and importance of the Major Branch System involved. This gives two Basic Sections of very unequal dimensions, but the ., Alps being of natural origin cannot be expected to fall into more or less equal com partments. Two rather less unbalanced sections could be obtained by differentiating Ticino.- and Adda-drainage on the Po-side, but this would exhibit both hydrographic and Alpine inferiority.

Nearly all models of orogeny build on this concept, and all mantle slab of them relate the stacking of nappes and the buildup of topography to compressional forces at work in response to the collision between two continental plates.

Botschaft Für Die Schamser Bevölkerung Zu Grundsatzent
Botschaft zur Gründung eines Schulverbandes Schams Der Kreisrat Schams hat im Herbst 2004 beschlossen, eine Arbeitsgruppe zur Überprüfung der Schulstrukturen im Schams einzusetzen. Vertreter aus dem Kreisrat, der Schulbehörden und des Lehrkörpers haben mit Unterstützung von auswärtigen Fachpersonen in mehreren Workshops und Sitzungen eine Projektskizze für einen Schulzusammenschluss im Schams erarbeitet. Die Schulstandortsgemeinden Andeer, Zillis und Donat haben die erarbeitete Projektskizze im Mai 2007 leicht überarbeitet. An der Kreisratsitzung vom 19. Juni 2007 haben alle Gemeindepräsidenten und Ratsmitglieder des Kreises Schams in Anlehnung an die Projektskizze eine Abstimmung über einen Schulzusammen- schluss in unserem Tal befürwortet. Der damals verabschiedete Text zu einem Zusammenschluss lautete wie folgt: Schulverband Schams: Für die Primar- und Oberstufe Schams wird ein Schulverband gegründet. Dieser löst die bestehenden Schulstrukturen ab. Die Oberstufe soll zusammengeführt und nach Möglichkeit mit dem Modell C in Zillis geführt werden. Die deutschsprachige Abteilung der Primarschule wird in Andeer geführt, die romanischsprachige Abteilung in Donat. Schülerinnen und Schüler, welche die romanische Schule besuchen wollen, werden in Donat aufgenommen. Schülerinnen und Schüler, welche keinen romanischen Kindergarten besucht haben, können die deutschsprachige Primarschule in Andeer besuchen. Die Primarschule Avers wird wie bis anhin (selbständig) weitergeführt! Die Oberstufenschüler von Avers können – aufgrund einer Vereinbarung – die Oberstufe in Zillis besuchen. Die Kindergärten bleiben soweit möglich in den jeweiligen Orten bestehen und sind nicht im Schulverband integriert. Zwischen Donat und Zillis werden bereits Möglichkeiten der Zusammenarbeit diskutiert. Schulführungsstruktur: Die vorgeschlagene Variante bringt mit sich, dass nur mehr eine Schulbehörde für das Schams notwendig ist. Um die operativ-administrativen Arbeiten effizient zu lösen, ist die Einsetzung einer teilzeitlich professionellen Schulleitung für die Schule Schams zu prüfen. -

Connecting Quartz Fluid Inclusion, Fissure Monazite Age, and Fissure
Gnos et al. Swiss J Geosci (2021) 114:14 https://doi.org/10.1186/s00015-021-00391-9 Swiss Journal of Geosciences ORIGINAL PAPER Open Access Episodes of fssure formation in the Alps: connecting quartz fuid inclusion, fssure monazite age, and fssure orientation data Edwin Gnos1* , Josef Mullis2, Emmanuelle Ricchi3, Christian A. Bergemann4, Emilie Janots5 and Alfons Berger6 Abstract Fluid assisted Alpine fssure-vein and cleft formation starts at prograde, peak or retrograde metamorphic conditions of 450–550 °C and 0.3–0.6 GPa and below, commonly at conditions of ductile to brittle rock deformation. Early-formed fssures become overprinted by subsequent deformation, locally leading to a reorientation. Deformation that follows fssure formation initiates a cycle of dissolution, dissolution/reprecipitation or new growth of fssure minerals enclos- ing fuid inclusions. Although fssures in upper greenschist and amphibolite facies rocks predominantly form under retrograde metamorphic conditions, this work confrms that the carbon dioxide fuid zone correlates with regions of highest grade Alpine metamorphism, suggesting carbon dioxide production by prograde devolatilization reac- tions and rock-bufering of the fssure-flling fuid. For this reason, fuid composition zones systematically change in metamorphosed and exhumed nappe stacks from diagenetic to amphibolite facies metamorphic rocks from saline fuids dominated by higher hydrocarbons, methane, water and carbon dioxide. Open fssures are in most cases oriented roughly perpendicular to the foliation and lineation of the host rock. The type of fuid constrains the habit of the very frequently crystallizing quartz crystals. Open fssures also form in association with more localized strike-slip faults and are oriented perpendicular to the faults. -

SCHMID1 & ALFONS BERGER3 Key words: Lepontine dome, meta-sediments, Fe-Mg carpholite, Barrovian metamorphism, high-pressure metamorphism, Alpine tectonics ABSTRACT The Cenozoic-age metamorphic structure of the Alps consists of a through- phase) HP/LT metamorphism under blueschist facies conditions (350–400 °C going pressure-dominated belt (blueschists and eclogites) that strikes parallel and 1.2–1.4 GPa) was immediately followed by “cold” isothermal (or cool- to the orogen and was later truncated by two thermal domes characterised ing) decompression during D2 nappe-stacking (Ferrera phase).

This related Barrovian overprint (500–570 °C and 0.5–0.8 GPa) postdates the D3 study documents for the first time that relics of Fe-Mg carpholite occur also nappe-refolding event (Domleschg phase) and represents a late heating pulse, within meta-sedimentary units that are part of the north-eastern Lepontine separated by D2 and D3 from the D1 high-pressure event.
