p.109: The WSW–ENE trending Arbostora Anticline occupies the southern part of the Varesotto Imbricates and is separated to the north, by the Marzio Fault, from a complex syncline of imbricated Mesozoic sediments. West of a complex transfer zone, thrusts are N-vergent, east of it S-vergent. With the Early Jurassic syn-rift sediments increasing towards the Monte Nudo Basin, the Arbostora Anticline plunges axially to the WSW and the Early Jurassic basinal sediments appear to form a N-vergent drape over the Marzio Fault (Schumacher 1997). The southern flank of the Arbostora Anticline disappears below the Monte Olimpino Backthrust, along which the Gonfolite Lombarda Group of the Milan Belt overthrusts the Varesotto Imbricates, forming a subsurface triangle zone (Bernoulli et al. 1989). The small imbricates of Mesozoic sediments to the south of the Arbostora Anticline, near Stabio, are interpreted as splays at the base of the Milan Belt in this triangle zone (Bernoulli et al. 2017, 2018).
