Sedimentary basins formed and carried piggyback on active thrust sheets

Heavy minerals from sedimentary rocks of the Malcov Formation and their palaeogeographic implications for evolution of the Magura Basin (Western Carpathians, Slovakia) during the Late Eocene – Late Oligocene

“…For ma tion and iso la tion of these sub-bas ins are as soci ated with Al pine tec ton ics and trans for ma tion of the rem nant Outer West ern Carpathians ba sin into a flexed fore land ba sin (e.g., Oszczypko, 2006). The sub-bas ins have char ac ter is tics of piggy-back bas ins (sensu Ori and Friend, 1984) de vel oped on the top of the fron tal part of the West ern Carpathians orogenic wedge, which con sti tutes a wedge-top depozone (sensu DeCelles and Giles, 1996) of the fore land ba sin. The na ture of the pro cesses and sed i ments in the sub-bas ins was also af fected by cli mate change at the bound ary be tween the Eocene and Oligocene (Ter mi nal Eocene Event) when sig nif icant cool ing of the cli mate and glacio-eustatic re gres sion started (e.g., Leszczyñski, 1997;Soták, 2010;OszczypkoClowes and Zydek, 2012).…”

Polyphase tectonic subsidence evolution of the Vienna Basin inferred from quantitative subsidence analysis of the northern and central parts

“…This basin stage was active from the Eggenburgian to the early Karpatian (Decker 1996;Fodor 1995;Jiříček and Seifert 1990;Seifert 1992Seifert , 1996. It is described as piggyback basin (wedge-top basin, Ori and Friend 1984), formed on top of active thrust sheets. Although the Eggenburgian sediments were restricted to the northern part of the Vienna Basin, during the Ottnangian and the early Karpatian the sedimentation spread to the central part (Decker 1996;Jiříček and Seifert 1990;Strauss et al 2006).…”

Updated picture of the Ligurian and Sub-Ligurian units in the Mt. Amiata area (Tuscany, Italy): elements for their correlation in the framework of the Northern Apennines

“…COSTA et alii, 1998;BARCHI et alii, 2001). From the Oligocene to the present day this deformation was accompanied by the development of foreland basins (foredeep and piggy-back basins of ORI & FRIEND, 1984) that were successively incorporated into the collisional belt (RICCI LUCCHI, 1986;ARUTA et alii, 1998;BARCHI et alii, 2001). During the middle Miocene the uppermost structural levels of the Apennines were affected by lowangle extensional faults formed due to the overthickening of the collisional belt (CARMIGNANI & KLIGFIELD, 1990;DECANDIA et alii, 1993).…”
