On the role of clay-carbonate reactions in speleo-inception : a contribution on the understanding of the earliest stage of karst channel formation = O vlogi reakcij med glinenimi minerali in karbonati pri začetju : prispevek k razumevanju najzgodnejše stopnje nastanka kraških kanalovPezdič, Jože ; Šušteršič, France, 1945- ; Mišič, MihaČlanek opozarja na možen, prej neopisan mehanizem začetja na kontaktu med dolomitom in apnencem. Terenski podatki so z Laškega Ravnika, okrog 3km severovzhodno od Planinskega polja (Slovenija). V tem ... predelu je mnogo kraškihkanalov nastalo vzdolž kontakta med apnencem in dolomitom ali vsaj v najbližji soseščini. Uvodoma smo preučili topnost kalcita in dolomita v temperaturnem rangu od 2 [sup] ) 0 C do 16 [sup] 0 C pri parciarnem tlaku CO [sup] 2 med 0.1 do 10%. S programom PHREEQOM smo preračunali različne kombinacije naravnih pogojev in možnih izidov. Upoštevali smo tudi možno navzočnost ujete morske vode z deležem do 20%. Rezultati kažejo, da začetje nakontaktif apnenca in dolomita, obogatenih z glinenimi minerali, pri sorazmerno nizkih temperaturah najlažje razložimo z dedolomitizacijo v navzočnosti glinenih mineralov in raztopljene kremenice. Prisotnost CO [sup] 2in glinenih mineralov lahko precese pospeši, medtem ko navzočnost morske vode poveča topnost kalcita in povzroči precipitacijo dolomitaSource: Acta carsologica = Krasoslovni zbornik. - ISSN 0583-6050 (27, št. 1, 1998, str. 187-200)Type of material - article, component part ; adult, seriousPublish date - 1998Language - englishCOBISS.SI-ID - 479061
