Pannonian marl lies between the underlying heterogeneous Sarmatian deposits and the over- lying set of Pontian sand beds and Quaternary sediments. The open pit is located on the NE range of Fruska Gora, a horst structure with a core of Paleozoic, Mesozoic and Paleogene rocks in a complex structural pat- tern. Pannonian sediments, which are part of a younger structural stage, deposited on the horst limbs. The Pannonian marl strata dip at angles from 12° to 26° (to the NNW), forming a monocline. The strata deforma- tions are a consequence of radial tectonics and are a potential source of landslides. The many mollusks (7 gas- tropod and 9 bivalve species) and ostracodes (27 species) and their biostratigraphical position indicate marl deposition throughout the Pannonian age. A paleomagnetic investigation established that the marl has incon- sistent remanent magnetization (with bad statistical parameters), which originates from neoformed magnetite.","PeriodicalId":263923,"journal":{"name":"Geoloski Anali Balkanskog Poluostrva","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115361747","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}

This primary characteristic of unsaturated soil, i.e., matric suction, should be included in laboratory testing and geotechnical analyses. Direct shear or triaxial testing of unsaturated soil are very expensive and time-consuming and require specially mod- ified equipment. Instead, the prediction of unsaturated shear strength using the soil water characteristic curve, SWCC, and the effective shear strength parameters c' and ϕ ' is a widely accepted practice. In this study, con- stitutive soil-water characteristic curves were obtained from the results of experimental testing by draining sat- urated soil samples under different pressures. This testing was performed for the first time in Serbia in a 15 bar pressure plate extractor according to ASTM standards. The laboratory testing included natural samples of loess sediments with the original macroporous structure and loess sediments with a destroyed soil structure. The influence of the grain-size distribution and natural soil structure on the unsaturated shear strength of Belgrade loess sediments above the ground water level was also evaluated. The obtained results are in accordance with the results from other investigations.","PeriodicalId":263923,"journal":{"name":"Geoloski Anali Balkanskog Poluostrva","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125175122","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}

It is particularly important to know the time and the primary depth of the formation of an ore-body and its recent position. \u0000The establishment of the vertical mineralization interval is considered in this work on the example of the Alsar Sb–As–Tl mineral deposit. The research methods used were geomorphological analysis (the principal exploration method), measurement of cosmogenic radioactive (10Be, 26Al) and stable (3He, 21Ne) nuclides to determine the erosion velocity (control method) and comparison of the obtained results with the geological exploration data from operative mine workings. Adetailed geological study of the formation of the Alsar deposit preceded the research. \u0000The research data are the following: depth interval of the ore-body is 10–50 m below the present ground surface; average level of erosion in the Alsar deposit area is 20–80 m over a period of 106years (Ma), or about \u0000100–400 m from the beginning of the volcanic activity to the present day (≈5 Ma); thickness of the eroded rock complex over the ore bodies from the beginning of the hydrothermal alteration and the formation of ore \u0000bodies (4.31 Ma) to the present is ≥150 m (Crven dol), or ≥230 m (central deposit); the palaeointerval of the formation of the ore-body is 230 m (200–430 m); and, finally, the potentially mineralized interval is deep, from 10 m to 280 m below the surface.","PeriodicalId":263923,"journal":{"name":"Geoloski Anali Balkanskog Poluostrva","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116045890","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}
