  • Lithofacies Definition Based on Cut-Offs in Indicator Kriging Mapping, Case Study Lower Pontian Reservoir, Sava Depression K
    Lithofacies definition based on cut-offs in Indicator Kriging mapping, case study Lower Pontian reservoir, Sava Depression K. Novak Zelenika ORIGINAL SCIENTIFIC PAPER Mapping of the lithofacies is very important for getting insight to sedimentary environments, shapes and boundaries of hydrocarbon reservoirs especially in reservoir characterization. Indicator Kriging technique is most often used for lithofacies mapping. It is based on indicator transformed input data, depending on presence or absence of the certain lithofacies. Indicator transformation of the input data is performed based on cut-offs into values 0 or 1. Turbidites were dominant clastic transport mechanism in the Croatian part of the Pannonian Basin System during the Early Pontian. Most of transported detritus had been eroded in the Eastern Alps and re-deposited several times before the suspended materials entered the Sava Depression. Due to long transport only medium and fine grained sands and silts (Tb - Td Bouma sequences) reached the Sava Depression. When turbiditic currents were not active, typical calm deep water sediment was deposited. It was presented how to use core and log data to define proper cut-offs for describing different lithofacies. Obtained results are probability maps and with a proper cut-offs definition some of them can show turbiditic channel and material transport direction. Key words: lithofacies, turbidites, Indicator Kriging, Upper Miocene, Sava Depression, Croatia 1. INTRODUCTION The Late Pannonian and Early Pontian periods belong to the 2nd transtensional phase.10, when thermal subsidence gen- erally re-opened many depressional areas along the entire Pannonian Basin Sys- tem, created depositional spaces for the accommodation of a huge volume of sandy ma- terial.

Zbog debelog slijeda kvartarnih naslaga na površini, prve informacije o dubinskoj građi dobivene su na temelju geofizičkih istraživanja u sedamdesetim i osamdesetim godinama 20. stoljeća. U ovom radu, jedini postojeći seizmički podaci su, zajedno s bušotinskim, interpretirani u računalnom programu Schlumberger Petrelu. Dostupni seizmički profili reinterpretirani su te prebačeni u dubinsko mjerilo kako bi se mogle konstruirati karte reprernih horizonata. Na temelju konstruiranih ploha horizonata napravljen je strukturni model istraživanog područja. U konačnici je pomoću metode umjetnih neuronskih mreža u programu Statistica predviđen litološki sastav na trasama seizmičkih profila. Svrha izrade modela je priprema podataka za procjenu ugljikovodičnog potencijala ovog izoliranog dijela podzemlja.

  • Influence of Mycorrhiza and Different Yeast Strains on Physical, Chemical and Organoleptic Properties of Graševina (Vitis Vnifera L.) Wine
    Athens Journal of Sciences- Volume 3, Issue 2 – Pages 101-112 Influence of Mycorrhiza and Different Yeast Strains on Physical, Chemical and Organoleptic Properties of Graševina (Vitis vnifera L.) Wine By Valentina Obradovic Josip Mesic† Brankica Svitlica‡ Maja Ergovic Ravancic The object of the mycorrhizal association between vine and fungus is to increase the absorption of water and/or nutrients from the soil. The aim of this research was to investigate the influence of mycorrhiza to the final product-wine. Besides, for the fermentation process authentic yeasts and four different commercial strains of yeasts were used. Grapes were grown in the wine growing region of Kutjevo, Croatia, in 2013. A typical variety from this region is Graševina. Obtained samples of wines were tested for alcohol, total acids, total polypfenol content (Folin-ciocalteu method), antioxidant activity (ABTS and DPPH method) and color hue. Sensory evaluation was done by professional tasters. Results showed that the usage of the different starter cultures of yeasts had different influences on wine depending on the mycorrhiza. Samples with mycorrhiza had a good extraction of polyphenols with the usage of authentic yeasts, while without micorrhiza starter cultures showed better results, which was evident in the physical and sensory properties as well. Keywords: Graševina, mycorrhiza, polyphenols, yeasts Introduction Graševina is the most widely spread white grape variety in Croatia. The most important synonyms are: Italien Riesling (Romania), Olasz Rizling (Hungary) Laški Rizling (Slovenia, Serbia), Welschriesling (Austria, Germany and Switzerland) (Robinson et al., 2012). It gives fine wines of average and outstanding quality, pleasant varietal aroma and flavor, with a medium content of acid (Mirošević and Turković, 2003).

Rocks from Mt. Papuk were investigated, in order to determine thermal conditions, by Kübler index (illite “crystallinity”) and Árkai index (chlorite “crystallinity”) while the b0-parameter of K-white mica was used to estimate the pressure conditions. Treatment with dimethyl-sulfoxide (DMSO) was used in order to ex- tend application of chlorite “crystallinity” measurements to kaolinite bearing samples. Results suggest temperatures between 250–300°C and pressures of 2–3 kb. Similar temperature data recorded from various lithologies implies the existence of a previously unknown post lower Triassic thermal event, (Alpine very low to low-grade metamorphism) affecting different complexes on Mt. Papuk. New data presented and discussed in this paper provides the basis for further research and interpretation of the tectono-metamorphic history of the studied area and its correlation with other similar European metamorphic complexes.

  • Organizing Committee: Preliminary Program: Registration Information
    The Organizing Committee of “THE 7TH INTERNATIONAL WORKSHOP ON THE NEOGENE FROM THE CENTRAL AND SOUTH-EASTERN EUROPE” has the pleasure to invite you to participate in the Workshop which will be organized in the town of Velika, Croatia from 28th to 31th of May 2017 together with the Regional Committee on Mediterranean Neogene Stratigraphy as an RCMNS interim colloquium. The Programme of the workshop covers actual problems and perspective fields of Neogene geology, with special focus on the Paratethys. Abstracts of scientific contribution will be published in the Proceedings of the Workshop. We hope that your active participation will contribute to a successful realization of the Workshop. The workshop will consist of three days of technical sessions and field excursions in the North Croatian Basin. The meeting will be held at the Educational and Visitors Centre in Velika, a place 12 kilometers away from Požega http://www.papukgeopark.com. Facilities will be available for presentation and demonstration purposes. Organizing committee: Koraljka Bakrač (Croatian Geological Survey) Marija Bošnjak (Croatian Natural History Museum) Marko Cvetković (University of Zagreb, Faculty of Mining, Geology and Petroleum Engineering) Ines Galović (Croatian Geological Survey) Valentina Hajek-Tadesse (Croatian Geological Survey) Morana Hernitz Kučenjak (E&P Research Laboratory Department, Exploration & Production BD, INA) Marija Horvat (Croatian Geological Survey) Marijan Kovačić (University of Zagreb, Faculty of Science, Department of Geology) Vlasta Premec-Fućek
