These are: (1) subtidal below fair-weather wave-base to higher-energy subtidal above fair-weather wave-base, (2) subtidal below fair-weather wave-base with episodic higher-energy influences and (3) peritidal.

The hypertrophied splenial, the heterodont dentition, the cementum deposition at the bases of the teeth, and the large subcircular resorption pits assign this type to the family Teiidae. The dentition is composed of conical, monocuspid teeth in the mesial region and transversely widened bicuspid teeth in the distal region.

Based on their facies characteristics, seven lithofacies units have been distinguished, which constitute four paleoenvironmental associations: top of the platform (shallow subtidal below and above the fair-weather wave-base), upper foreslope, toe-of-slope and basin. The environmental changes are interpreted to be related to tectonic activity as a consequence of regional extensional movements, connected with the opening of the Dinaridic branch of the Neo-Tethys. These extensional movements resulted in multi-stage drowning of the northeastern part of the Adriatic carbonate platform, leading to its gradual back-stepping and accordingly the expansion of the pelagic basin. The interpretation presented here can serve as a useful model for re-evaluating previously analyzed sections of the Adriatic Carbonate Platform margin.","PeriodicalId":107929,"journal":{"name":"Acta Geologica Hungarica","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121071970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sampled areas cover SW Slovenia (Vipava and Brkini Basins) and the Istrian Peninsula (Trieste-Koper and Pazin Basins). Framework constituents of the lithic arenites reveal low-grade metamorphic, acidic plutonic, and to a lesser extent, mafic volcanic and ultrabasic sediment sources, with evidence for a small degree of sediment recycling as well. Among the processes that commonly influence sediment compositions, weathering in the source and sorting were probably negligible, but carbonate contribution of detrital or intrabasinal origin diluted the siliciclastic portions to various degrees. Main and trace element compositional data agree well with petrography and clearly indicate the predominance of felsic, crustal source lithologies. Exposed mafic-ultramafic source units were volumetrically less important. From the Early Paleogene, extensive sediment mixing occurred in front of the Dinaride orogenic thrust wedge, with the components derived from different Dinaride units of felsic crystalline basement, platform carbonates and ophiolite. In the Eocene, a likely source of the mafic-ultramafic detritus was the Jurassic ophiolitic melange in the NE Dinarides.","PeriodicalId":107929,"journal":{"name":"Acta Geologica Hungarica","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123196047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Possibilities of local evaluation of the gh values and ranges of influence are presented. The main idea of the paper is that the gh values and the ranges of influence are continuous random variables.
