Povzetek

Članek obravnava zakrasevanje ob narivnem kontaktu dolomita in apnenca v Idrijskem Logu in Koševniku. Ob narivnem stiku se je oblikoval neke vrste kontaktni kras. V dolomitu je površinska kraška oblikovanost slabše izražena, v krednih apnencih pa so nastale številne vrtače, brezna in požiralniki. Brezna v apnencih in vrtače v dolomitu kažejo genetsko povezanost na narivni kontakt, freatične oblike pa so nastajale globoko pod narivnim pokrovom.

The paper discusses karstification along the thrust contact between dolomite and limestone at Idrijski Log and Koševnik (west-central Slovenia). Thrust contact induced the formation of a specific contact karst assemblage. Karst morphology is less strongly expressed within the dolomite, whereas the limestones are deeply karstified, with many dolines, shafts and sinkholes. Shafts in limestone and dolines in dolomite show genetic relationship with the thrust contact, whereas preserved fragments of phreatic features originated deep beneath the thrust plane.
