摘要: Abstract The Alpine–Dinaric Transition Zone in Slovenia comprises the fold and thrust belt of Southern Alps (South Karawanken Range, Julian Alps), Slovenian Basin Dinarides. located between Dinaric carbonate platforms evolved during Middle Triassic time remained a deep marine setting till Late Cretaceous. thermal history Carboniferous to Eocene rocks that area was investigated using vitrinite reflectance (VR) data, apatite fission track analysis numeric 1D basin modeling. study shows maturity patterns are mainly controlled by thickness Upper Cretaceous flysch deposits, filling accommodation space. Therefore overprint reaches maximum (> 4%Rr) sediments decreases towards north south. Minor sedimentary burial Adriatic Carbonate Platform results lower ( 2 ). Cooling Paleozoic Mesozoic below 110 °C occurred Early Oligocene times different parts area. Nappe stacking due (Dinaric) Cenozoic (Alpine) compressional tectonics did not influence sediments.
