According to structure the limestone is biomicrite of wackstone-packstone type. Among the mentioned beds there are the most probably the syngenetic breccias too. Fossil remains and sedimentological data show that the mayor part of the Vreme beds was deposited in a shallow sea. On the treated area there are in Vreme beds 6,2% of all the caves only, or 0,3 cave/km2 respectively, which means two thirds bellow the averageVremske plasti (maastrichtij) sestavljajo predvsem drobnoplastni temni apnenci, ki so ponekog močno bituminozni, redkeje laporni apnenci in premogovi skrilavci ter ponekod vložki premoga. Po strukturi je apnenec biomikrit tipa wackstone-packstone. Med omenjenimi plastmi se pojavljajo tudi breče, ki so najverjetneje singenetskega nastanka. Fosilni ostanki kažejo, da se je večji del vremskih plasti sedimentiral v plitvem morju. Na obravnavanem ozemlju je v vremskih plasteh samo 6,2% vseh jam oziroma komaj 0,3 jame/km2, kar je dve tretjini pod povprečjemTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZRC SAZU
