“…). Only three Jurassic or Cretaceous ages were identified (155.2, 92.1 and 83.3 Ma), and the two Cretaceous ages display very low Th/U ratios (0.004 to 0.008), suggesting that these grains likely originated in a metamorphic environment (Rubatto, ; Anfinson et al ., ).…”

Sediment routing evolution in the North Alpine Foreland Basin, Austria: interplay of transverse and longitudinal sediment dispersal

Integration of detrital zircon geochronology and three-dimensional (3D) seismic-reflection data from the Molasse basin of Austria yields new insight into Oligocene-early Miocene palaeogeography and patterns of sediment routing within the Alpine foreland of central Europe. Three-dimensional seismic-reflection data show a network of deep-water tributaries and a long-lived (>8 Ma) foredeepaxial channel belt that transported Alpine detritus greater than 100 km from west to east. We present 793 new detrital zircon ages from 10 sandstone samples collected from subsurface cores located within the seismically mapped network of deep-water tributaries and the axial channel belt. Grain age populations correspond with major pre-Alpine orogenic cycles: the Cadomian (750-530 Ma), the Caledonian (490-380 Ma) and the Variscan (350-250 Ma). Additional age populations correspond with Eocene-Oligocene Periadriatic magmatism (40-30 Ma) and pre-Alpine, Precambrian sources (>750 Ma). Although many samples share the same age populations, the abundances of these populations vary significantly. Sediment that entered the deep-water axial channel belt from the west (Freshwater Molasse) and southwest (Inntal fault zone) is characterized by statistically indistinguishable age distributions that include populations of Variscan, Caledonian and Cadomian zircon at modest abundances (15-32% each). Sandstone from a shallow marine unit proximal to the northern basin margin consists of >75% Variscan (350-300 Ma) zircon, which originated from the adjacent Bohemian Massif. Mixing calculations based on the Kolmogorov-Smirnoff statistic suggest that the Alpine fold-thrust belt south of the foreland was also an important source of detritus to the deepwater Molasse basin. We interpret evolving detrital zircon age distributions within the axial foredeep to reflect a progressive increase in longitudinal sediment input from the west (Freshwater Molasse) and/or southwest (Inntal fault zone) relative to transverse sediment input from the fold-thrust belt to the south. We infer that these changes reflect a major reorganization of catchment boundaries and denudation rates in the Alpine Orogen that resulted in the Alpine foreland evolving to dominantly longitudinal sediment dispersal. This change was most notably marked by the development of a submarine canyon during deposition of the Upper Puchkirchen Formation that promoted sediment bypass eastward from Freshwater Molasse depozones to the Molasse basin deep-water axial channel belt. The integration of 3D seismic-reflection data with detrital zircon geochronology illustrates sediment dispersal patterns within a continental-scale orogen, with implications for the relative role of longitudinal vs. transverse sediment delivery in peripheral foreland basins.

“…Thus, an integration of the different analytical datasets applied to detrital zircons in sedimentary basins offers the possibility to assess the tectonic evolution history of the orogen from which the sediments were derived in terms of ages, rock types and source materials (Wysoczanski et al, 1997;Carter and Moss, 1999;Bruguier et al, 1997;Cawood et al, 2012). Detrital zircon age patterns and Lu-Hf isotopic analysis were recently used to unravel the origin of terrigenous sediments and the growth of the crusts in the Western Alps in a situation close to Alpine Corsica environment (Bütler et al, 2011;Beltrán-Triviño et al, 2013;Malusà et al, 2013Malusà et al, , 2016aManzotti et al, 2015Manzotti et al, , 2016Chu et al, 2016 and references therein; Anfinson et al, 2016).…”

“…The potential source regions for the young Eocene-Oligocene zircons (Supplementary File 4 ) include the European plate, on the northern/western side of the Alps-Apennine system and/or the Adria Plate on the eastern/southern side 18 . Potential source regions of the European plate that were exposed by 30 Ma include magmatic active zones in Corsica-Sardinia and Provence-Esterel or rocks from the Alpine foreland basins, such as the Taveyanne Sandstones.…”

“…Potential sources on the Adria Plate include the Periadriatic igneous complexes associated with, from west to east, the Biella, Bergell and Adamello plutons in the Alps 18 , 21 . The plutons themselves are no potential sources, since they were not exhumed before 10 Ma 22 – 24 , nevertheless their ages are important in suggesting ages of potential volcanic activities and/or antecrystic zircons that volcanoes can erupt.…”

We have traced the particle path of high-pressure metasedimentary rocks on Elba Island, Northern Apennines, with the help of a U-Pb-Hf detrital zircon study. One quarter of the analysed zircons are surprisingly young, 41-30 Ma, with a main age peak at ca. 32 Ma, indicating an unexpected early Oligocene maximum deposition age. These Oligocene ages with negative εHf indicate a volcanic source region in the central-southern Alps. Though young by geological means, these zircons record an extraordinary geodynamic history. They originated in a volcanic arc, during the convergence/collision of the the Adria microplate with Europe from ca. 65 to 30 Ma. Thereafter, the Oligocene zircons travelled ca. 400 km southward along the Adria margin and the accretionary prism to present-day Tuscany, where they were subducted to depths of at least 40 km. Shortly thereafter, they were brought to the surface again in the wake of hinge roll back of the Apennine subduction zone and the resulting rapid extensional exhumation. Such a zircon roller coaster requires a microplate that has back-to-back subduction zones with opposing polarities on two sides.
