In addition, all more important results from published works are considered (BI-ONDI} et al, 1997;BLA{KOVI}, 1999;COLIZZA et al, 1989;CUCCHI et al, 1989a,b;^AR & GOSPODARI~, 1983/84;JURKOV{EK et al, 1996;POLJAK & RI`NAR, 1996;MARIN~I} & MATI~EC, 1991;MATI~EC, 1994;MLAKAR, 1969;MLAKAR & PLACER, 2000;PERUZZA et al, 2002;PLACER & ^AR, 1997;PLACER, 1981PLACER, ,1982PLACER, , 1996PLACER, , 2005PLACER, , 2007PLACER, , 2008aPLACER, , 2008bPONTON, 2002). This paper is also based on published data from structural mapping of the motorway section Diva~a -Koper across the Istria-Friuli Underthrust Zone in years 1999 -2005, and Razdrto -Vipava, as well as the data from additional mapping of Razdrto -Senože~e road section, and of the seashore from Lazaret to Piran, and field inspections of key structural localities in the region between the Southern Alps and Velebit Mts.…”
