20.500.12556/RUL-73233 Sedimentološka analiza jamskih sedimentov v krednoh apnencih na Fortunovem klancu pri Logatcu sedimentological analysis of cave sediments in Cretaceous limestone at Fortunov klanec near Logatec Raziskave za diplomsko delo so potekale na območju Logatca, na cestnem odseku med Logatcem in priključkom na avtocesto. Na tem območju se nahaja izdanek apnenčevih plasti in na desni strani, gledano v smeri JZ, tudi zasuta kraška jama, ki se je v preiskovanih apnencih tudi razvila. V diplomskem delu so podrobneje opisane strukture in teksture jamskih sedimentov in krednih apnencev ter njihova mineralna sestava. Izdelan je bil profil tako za jamske sedimente kot tudi za kredne apnence in analiza s praškovno rentgensko difrakcijo. Rezultati so pokazali, da gre pri jamskih sedimentih za klastite, natančneje za kremenove in boksitne breče in konglomerate, ter za peščenjake, med njimi pa je pomešana tudi siga kot avtohtoni material. Raziskala sem tudi kredne apnence, ki so nastali s sedimentacijo na območju Dinarske karbonatne platforme in vsebujejo veliko fosilnih združb, kot so miliolidne foraminifere, orbitoline, fragmenti polžev in školjk, ter peloidov. Sedimentacija je potekala v plitvovodnem okolju v laguni in obalnem delu ter v bolj robnih delih platforme. Research for this thesis took place in the Logatec area along the road section between Logatec and the highway connection. In this area limestone layers are located, including a filled in Karst cave on the right side towards south-west, which developed out of the same limestone layers. This thesis describes in more detail the structure and texture of the cave sediments and cretaceous limestone as well as their mineralogical composition. The profile as well as the powder X-ray diffraction analysis has been made for the cave sediments and cretaceous limestone. The results classified the cave sediments as clastites, namely quartz and bauxite breccias and conglomerates, as well as sandstones sometimes mixed with flowstone as the indigenous material. I have also researched the cretaceous limestone, which incurred by sedimentation in the Dinaric Carbonate Platform area and contains many fossil aggregates such as miliolid foraminifera, orbitoline, fragments of gastropods and bivalves as well as peloids. Sedimentation took place in the shallow-water environment, namely the lagoon and coastal parts as well as the more edge parts of the platform. sedimentologija jamski sedimenti kreda apnenci Fortunov klanec pri Logatcu true false false [K.
