“…The link between detrital modes and plate tectonics has been widely used within modern and ancient systems alike (e.g. Dickinson and Suczek, 1979;DeCelles and Hertel, 1989;Graham et al, 1993;Hendrix, 2000;James et al, 2007;Stefani et al, 2007). However, other factors can influence sediment detrital modes, including climate (Suttner et al, 1981;Johnsson et al, 1991;Savage and Potter, 1991), depositional environment (Mack, 1978;Garzanti, 1986;Marenssi et al, 2002), and diagenesis (McBride, 1987;Giles, 1997).…”

“…Unstable climate conditions occurred at the Eocene–Oligocene boundary, and continued through the Oligocene period (Haq et al ., ; Miller et al ., , , , , ; Zachos et al ., ; Wade and Pälike, ; Pälike et al ., ; Kominz et al ., ; Cramer et al ., ; Francis et al ., ), also affecting the Alpine area (Di Giulio et al ., ; Kuhlemann et al ., ; Kuhlemann, ; Di Capua et al ., ). The diachronous influx of Southalpine clastic sedimentation of the Southalpine Foredeep (Mellere et al ., ; Stefani et al ., ; Sciunnach et al ., ), seems to corroborate a primary tectonic control on sediment production, rather than a climatic one. The relatively small extension of the basin and the emergence of an embryonic relief‐drainage system (Mancin et al ., ; Castellarin et al ., ; Garzanti and Malusà, ; Zanchetta et al ., ), might reflect a synchronous sedimentary response to a globally recognized sea‐level drop.…”

Clastic sedimentation in the Late Oligocene Southalpine Foredeep: from tectonically controlled melting to tectonically driven erosion

The Villa Olmo Conglomerate (lower member of the Como Conglomerate Formation, Gonfolite Lombarda Group, Southern Alps, Italy) represents the first coarse clastic inputs into the Oligocene Southalpine Foredeep. A number of techniques including sedimentary lithofacies analyses, clast counts on turbidite conglomerate bodies, sandstone petrography through Gazzi–Dickinson point‐count method and XRF analyses, and optical and minero‐chemical analyses on single clasts have been performed, in order to better define the sediment source area and geodynamic conditions which promoted sedimentation in the Southalpine Foredeep at the end of the Oligocene. The Villa Olmo Conglomerate interdigitates with the upper part of the Chiasso Formation, and gradually passes upward into the overlying Como Conglomerate Formation. Provenance analyses (conglomerate clast counts and sandstone petrography) reveal a strong metamorphic provenance signal, likely sourced from eroded Southalpine basement. An increase in igneous plutonic clasts reflects sediment supply from the Southern Steep Belt and a decrease of volcano‐sedimentary Mesozoic cover sequences. Optical and minero‐chemical analyses on volcanic detritus detect the presence of sub‐intrusive to effusive, andesite to rhyolite products, ascribable to the Varese‐Lugano Permian volcanoclastic suite, as well as Oligocene andesite products. Plutonic clasts document the presence of tonalites, granites, and brittle deformed granodiorites (with two micas), being likely sourced from the tonalite tail of the Bergell Pluton and the plutonic units of the Bellinzona‐Dascio Zone. The identification of this provenance suite implies palaeo‐drainage from the region between Varese (Southern Alps) and the Bellinzona‐Dascio Zone (Central Alps). The Villa Olmo Conglomerate is the first depositional record of the onset of tectonically driven erosion in the Alpine belt. We infer that the previous low sediment budget regime (Eocene–Middle Oligocene) was a consequence of a tectonically controlled melting phase, during which tectonic events promoted magmatic production in the middle crust of the Central Alps at rates higher than those of crustal deformation, so inhibiting sediment production. We conclude that changes in the deep structures of the Alpine Orogenic chain have controlled the main geodynamic processes during Oligocene–Neogene times, and have controlled sediment composition and supply into the Southalpine Foredeep.

“…In multisourced foreland basin systems, flat, elongate foredeeps commonly promote unidirectional, bipolar patterns of turbidite sedimentation, fed by both longitudinal and transversal sources, resulting in vertically stacked turbidites of significantly different composition, which reflect a pure autogenic control (Gandolfi et al, 1983;Ricci Lucchi, 1986;Stefani et al, 2007).…”
