12. A glimpse of the lost Upper Triassic to Middle Jurassic architecture of the Dinaric Carbonate Platform margin and slopeBoštjan Rožič, Luka Gale, Primož Oprčkal, Astrid Švara, Tomislav Popit, Lara Kunst, Dragica Turnšek, Tea Kolar-Jurkovšek, Andrej Šmuc, Aljaž Iveković, Jan Udovč, David Gerčar, 2022, izvirni znanstveni članek Povzetek: In the southernmost outcrops of the Slovenian Basin the Middle Jurassic coarse-grained limestone breccia (mega)beds are interstratified within a succession that is otherwise dominated by hemipelagites and distal turbidites. In this paper, these beds are described as the Ponikve Breccia Member of the Tolmin Formation. We provide descriptions of the studied sections with detailed geological maps and analysis of the breccia lithoclasts. From the latter, a non-outcropping margin of the Dinaric Carbonate Platform is reconstructed. In the Late Triassic the platform margin was characterized by a Dachstein-type marginal reef. After the end-Triassic extinction event, the platform architecture remained, but the reefs were replaced by sand shoals characterized by ooids. In the late Early Jurassic and/or early Middle Jurassic a slope area might have been dissected by normal faults and a step-like paleotopography was formed. In the Bajocian, during a period of major regional geodynamic perturbations, extensional or transtensional tectonic activity intensified and triggered the large-scale collapses of the Dinaric Carbonate Platform margin producing the limestone breccias described herein. This may in turn have caused a backstepping of the platform margin, as is evident from the occurrence of Late Jurassic marginal reefs that are installed directly above the Upper Triassic and Lower Jurassic inner platform successions.

16. Low-grade metamorphic rocks of the Tethys subduction–collision zone in the Medvednica Mt. (NW Croatia)Mirko Belak, Damir Slovenec, Tea Kolar-Jurkovšek, Vesnica Garašić, Zoltán Pécskay, Darko Tibljaš, Ivan Mišur, 2022, izvirni znanstveni članek Povzetek: The low-grade metasedimentary rocks of Medvednica Mt. (Northwest Croatia) are associated with ortho-greenschists (metabasalts). The Lower to Upper Triassic age of the protolith of the low-grade metamorphic rocks belonging to the Stari Potok, Adolfovac, Tusti Breg, Bliznec, Mrzljak, and Sljeme lithostratigraphic units is determined on the basis of conodonts and field relationships. The metamorphic age of the Triassic metasedimentary rocks from the Risnjak lithostratigraphic units is assumed to be Jurassic. Petrographic and geochemical analyses of ortho-greenschists point to a tholeiite basic magmatic protolith rock having T-MORB (transitional midocean-ridge basalt) characteristics. The ortho-greenschists of the Sljeme lithostratigraphic unit underwent retrograde metamorphism and show metamorphic zoning from the epidote–amphibolite facies to the lower parts of the greenschist facies. However, the greenschists of the Tusti Breg and Bliznec units are characterized by prograde metamorphism ranging from lower to higher greenschist facies. This metamorphism is associated with Jurassic subduction (165–150 Ma) and closure of the Western Tethys. Retrograde metamorphism took place during the collision of the Adriatic and Eurasian plates in the Lower Cretaceous (125–110 Ma).

17. Kemijska sestava in potencialna uporabnost lignoceluloznih ostankovJanja Zule, Tea Kapun, Ema Fabjan, 2022, izvirni znanstveni članek Povzetek: Namen raziskave je bil določiti kemijsko sestavo tipičnih lignoceluloznih ostankov, ki nastajajo v lesno predelovalni industriji, sadjarstvu, vinogradništvu in pri urejanju zelenih površin. Analizirali smo štiri skupine vzorcev, in sicer lesno žagovino, drevesno skorjo, zeleni odrez in olesenele ostanke sadežev, da bi ugotovili vsebnost pepela, lipofilnih in hidrofilnih ekstraktivov, celuloze, hemiceluloze in lignina. Pri analizah smo uporabili gravimetrične metode, čistost izoliranih frakcij pa smo potrjevali s pomočjo FTIR-spektroskopije. Največ pepela in nizkomolekularnih ekstraktivnih komponent smo zaznali v vzorcih skorje in zelenega odreza, najvišje koncentracije celuloze in celokupnih ogljikovih hidratov pa smo izmerili v žagovini. Oleseneli ostanki sadežev in skorja so se izkazali kot bogat vir lignina. Vsi obravnavani materiali so zaradi svoje raznolike kemijske zgradbe potencialne surovine za proizvodnjo bazičnih kemikalij in drugih specifičnih produktov v sklopu biorafinerijskih procesov.
