In the frame of the Antarctic Research Program of Italy (PNRA), the studies on the Early Paleozoic Ross Orogeny are coordinated in a mainframe project named "Chronologic-dynamic zoning of the Ross Orogen", including seven research units. The research work is focused on two main geographical-conceptual themes: (A) the reconstruction of the igneous-metamorphic history of the margin active in Victoria Land, carrying evidence for long-lasting igneous activity of variable chemical affinity and emplacement style, and (B) the role of the transition between fault-bounded lithotectonic units, which have been the reference frame for the interpretation of the Ross Orogeny in northern Victoria Land for two decades. At ISAES X, several preliminary and mature products of this research program are presented.
