“…Medvednica and the hilly ter rain to the north of it, which ex tends into Slovenia (Zagorje Re gion), is strongly con trolled by the pres ence of Late Mio cene-Qua ter nary folds and pop-up struc tures (e.g., Takšiae, 1965;Šimuniae et al, 1983;Tomljenoviae and Csontos, 2001). These struc tures mark the east ward pro lon ga tion of the Sava folds re gion of Slovenia (Sikošek, 1971;Placer, 1999), a zone of ac tive E-W to NE-SW-trending ranges (anticlines) and valleys (syn clines; Fig. 1).…”

1 Fac ulty of Min ing, Ge ol ogy and Pe tro leum En gi neer ing, Uni ver sity of Zagreb, Pierottijeva 6, Zagreb, Croatia Mt. Medvednica is an inselberg in NW Croatia, which lies at the in ter sec tion be tween the Southeastern Alps, Northwestern Dinarides and Tisza Mega-Unit of the Pannonian Ba sin. Due to the Pliocene-Quaternary N-S di rected short en ing, Mt. Medvednica ex pe ri enced 1500-2000 m of dif fer en tial up lift and now ex poses pre-Neo gene and Neo gene tec tonic and stratigraphic units that are sur rounded by Pliocene-Quaternary sed i ments. This pa per eval u ates a set of quan ti ta tive morphometry meth ods used to iden tify tec toni cally ac tive ar eas within this re gion characterized by low-rate ac tive fold ing and fault ing dur ing the Pliocene-Quaternary. Our anal y sis em ployed ex trac tion of hypsometric curves, cal cu la tion of a hypsometric in te gral, asym me try fac tor, and sta tis ti cal pa ram e ters of lon gi tu di nal stream pro files along 36 drain age bas ins de lin eated from a 25 m res o lu tion DEM of Mt. Medvednica area. De spite lithological het er o ge ne ity of the study area, the morphometric pa ram e ters we ob tain are good in di ca tors for dis crim i nat ing tec toni cally ac tive from in ac tive ar eas. We in terpret that the most tec toni cally ac tive ar eas are lo cated at the SW cor ner and in the cen tral part of Mt. Medvednica, where they are likely re lated to the North Medvednica Bound ary Fault, and to the Kašina Fault, re spec tively. The lat ter di vides the range into dis tinct NE and SW mor pho log i cal and struc tural ar eas.

“…In the Sava folds nappe structure, units occur that lie structurally above the Trnovo nappe. The contact of the two tectonic settings is the Želimlje fault, which passes over the central part of the External Dinarides along the eastern rim of the Ljubljansko barje and the western rim of Ljubljana basin (Placer, 1998a(Placer, , b, 2008.…”

Shallow geothermal energy is a renewable source of energy. Using it provides benefits for climate, health and economy. A prerequisite for its efficient and sustainable use is the knowledge of its potential as well as the barriers that limit its use. The paper presents the preliminary results of research carried out within the GeoPLASMA-CE project for the assessment of the shallow geothermal potential in the area of the City of Ljubljana. By compiling existing geological data and field work, a detailed geological map of the study area was elaborated. The spatial distribution of thermal conductivity was estimated with measurements of thermal conductivity on 47 representative samples of 18 lithostratigraphic units and field measurements in unconsolidated sediments at 12 localities. The measured values range between 0.63 and 5.18 Wm -1 K -1 . Continuous groundwater temperature measurements in 17 observation wells with depth to 118 m show relatively small temperature changes over time of 5 months. The measured values on the Ljubljansko polje range between 10.6 °C and 14.6 °C, while in the Ljubljansko barje the temperature increases up to 15.6 °C. Multi-level groundwater temperature measurements in 9 observation wells indicate three different conditions: both negative and positive temperature gradients and a constant temperature in different depths of the aquifer, which reflects the deeper geothermal or hydrogeological conditions and the anthropogenic impact. IzvlečekPlitva geotermalna energija je obnovljiv vir energije. Njena raba omogoča ugodne učinke na podnebje, zdravje in gospodarstvo. Pogoj za učinkovito in trajnostno rabo geotermalne energije je poznavanje potenciala, kakor tudi ovir, ki omejujejo njeno rabo. V članku smo predstavili prve rezultate raziskav za oceno plitvega geotermalnega potenciala na območju mesta Ljubljana, ki se izvajajo v okviru projekta GeoPLASMA-CE. Z usklajevanjem obstoječih geoloških podatkov in terenskimi raziskavami je bila izdelana natančna geološka karta. Prostorska porazdelitev toplotne prevodnosti kamnin (18 litostratigrafskih enot) je ocenjena z meritvami na 47 reprezentativnih vzorcih in s terenskimi meritvami nekonsolidiranih sedimentov na 12 lokacijah. Izmerjene toplotne prevodnosti kamnin so v razponu med 0,63 in 5,18 Wm -1 K -1 . Zvezne meritve temperature podzemne vode v 17 opazovalnih vrtinah do globine 118 m kažejo relativno majhne spremembe v 5 mesečnem obdobju. Izmerjene vrednosti na Ljubljanskem polju so v razponu med 10,6 °C in 14,6 °C, na Ljubljanskem barju pa naraščajo do 15,6 °C. Temperature podzemne vode izmerjene na različnih globinah v 9 vrtinah kažejo tri različne razmere: negativni in pozitivni temperaturni gradient ter konstantno temperaturo v različnih globinah vodonosnika, kar odraža globlje geotermalne ali hidrogeološke razmere ter antropogeni vpliv.

Increasing reports of genus Retropluma Gill, 1894 from the siliciclastic sediments of South-East Europe demonstrate the abundance and preferred habitat of this genus in Miocene seas of Central Paratethys. In the present paper we report new specimens of decapod Retropluma slovenica Gašparič & Hyžný, 2014, which extend the known palaeogeographic and stratigraphic distribution of the species to the western borders of Slovenian Basin of the Central Paratethys. The described specimens originate from the Early Miocene locality of Rovček in the Tunjice Hills in Slovenia and exhibit associated preservation, characteristic for endobenthic infaunal mode of living. IzvlečekVse več najdb rakovice rodu Retropluma Gill, 1894 v klastičnih kamninah jugovzhodne Evrope kaže na to, da so bile v miocenskem morju Paratetide pogostejše kot smo doslej predvidevali. V članku predstavljamo nove najdbe rakovice Retropluma slovenica Gašparič & Hyžný, 2014, ki dopolnjujejo naše poznavanje paleogeografske in stratigrafske razširjenosti vrste do najbolj zahodnih delov Slovenskega bazena v miocenskem morju Centralne Paratetide. Opisani so primerki iz spodnjemiocenskih govških plasti iz nahajališča Rovček v Tunjiškem gričevju. Primerki so ohranjeni s povezanimi okončinami, kar je značilno za rakovice, ki so se vkopavale v podlago. GEOLOGIJA 60/1, 77-85, Ljubljana 2017
