[en] The tectonic evolution of Northern Switzerland is characterized by a superposition of events, with the preceding ones strongly influencing their successors. The oldest, stratigraphically documented one is the late Paleozoic trough of Constance-Frick. It was recently discovered on reflection lines and in drill holes. Seismic evidence suggests a dextrally-transpressive belt with occasional transtensive episodes and rapidly varying depths, reaching down to 7 km. This picture fits into the frame of a broad dextral transform belt between the Appalachians and the Urals which has been postulated for this time interval. Before the transgression of the Mesozoic the relief was reduced to a peneplain, and this was followed by rather quiet subsidence that lasted for almost 200 my, although probably interrupted in the Cretaceous. It was followed by renewed tectonic activity in the Paleogene. Between the late Eocene and the early Miocene there was a largely extensional period which is documented for the Alps and their northern, western and southern foreland. In this period, a number of the Paleozoic fault zones were reactivated, mainly as comparatively gentle flexures which were accentuated by minor faults. This relief was peneplained again before the Langhian. With the middle Miocene, an entirely new tectonic situation originated ('Miocene revolution'). The stress field was re-oriented. In the area of the southern Rhinegraben a large dome, rooting in the lithosphere, began to rise (Black Forest-Vosges dome). The Alps began again a part of the compressive Africa-Europe plate boundary (Neo-Alps). Their northern front progressively penetrated the foreland, and their final addition, in the late Miocene, was the decollement nappe of the Jura. The sole of this thrust sheet had been strongly disturbed by the Paleogene deformations. 46 refs., 8 figs

[en] Detailed structural and sedimentological studies have been conducted in two areas near the Val Vedello uranium mine in northern Italy. These studies indicate that both the Variscan basement (locally called the Orobic basement) and the Permian cover rocks were thrust southward during the Alpine orogeny. Variscan mylonitic zones were rejuvenated during the Alpine orogeny and became fault boundaries for the Permo-Triassic basins. Alpine faults also are related to contemporaneous east-west folds and these faults have displaced Permo-Triassic uranium deposits. Uranium mineralisation is attributed to a Late Permian to Triassic geothermal event which leached uranium from Permian ignimbrites and transported it along Permo-Triassic faults. Detailed mapping indicates that the host sediments formed in an arid, closed basin characterised by alluvial fans and perennial saline lakes. (orig.)

[en] There is evidence for elevation-dependent warming (EDW) in many mountainous regions, including the Alps, Rockies, and Tibetan Plateau, all of which are in mid latitudes. Most studies finding evidence of EDW indicate that both recent decadal and future projected warming rates are greater at higher elevations. In this study, we examine the roles of Arctic amplification and elevation on future warming rates in winter and summer in eastern Siberia (50–70° N; 80–180° E). This region includes four major river basins that flow into the Arctic Ocean (the Yenisei, Lena, Indigirka, and Kolyma) and intersects with mountain ranges in northern Mongolia and eastern Siberia. We analyze projected 21st century temperature projections using a six-member ensemble of the National Center for Atmospheric Research (NCAR) Community Climate System Model (CCSM4) with a radiative forcing of 8.5 W m⁻². Projected warming rates in winter for the 21st century are dominated by Arctic amplification, which leads to significantly larger warming rates at higher latitudes, with latitudinal gradients of about 0.16 °C degree⁻¹ latitude. In summer, the latitudinal gradient is near zero (0.02 °C degree⁻¹ of latitude). Within specific latitude bands, we also find EDW. However, unlike most mid-latitude locations where warming rates are greater at higher elevations, we find that future warming rates are smaller at higher elevations for this high-latitude region, particularly during winter, with statistically significant rates varying between −0.70 °C km⁻¹ and −2.46 °C km⁻¹ for different 5° latitude bands. The decrease in warming rates with elevation in winter at the highest latitudes is primarily attributed to strong inversions and changes in the lapse rate as free-air temperatures warm at slower rates than surface temperatures. In summer, the elevation dependence is much weaker than in winter but still statistically significant and negative in all but the most northern latitude band with values ranging between −0.10 °C km⁻¹ and −0.56 °C km⁻¹.
