A detailed stratigraphy of Jurassic and Cretaceous deep-water sediments in the Julian Alps is presented. The study areas are located at Mt. Mangart, in the Triglav Lakes Valley and in the broader surroundings of Bovec. The successions are paleogeographically attributed to the Bovec Basin and the Julian High, and correlated with similar successions elsewhere in the Southern Alps. The sedimentary evolution is reconstructed and discussed in relation to synsedimentary tectonics, eustatic sea-level fluctuations and global paleoceanographic changes. The monograph is a fundamental publication for stratigraphy and sedimentology of Jurassic and Cretaceous deposits in the Julian Alps. Avtor v monografiji podaja detajlno stratigrafsko razčlenitev jurskih in krednih globljemorskih zaporedij na več lokalitetah v Julijskih Alpah – na Mangartu, v Dolini Triglavskih jezer in v širši okolici Bovca. Stratigrafska zaporedja primerja s podobnimi zaporedji v severni Italiji in sedimentarno evolucijo ozemlja razlaga v povezavi z regionalnimi tektonskimi premiki, evstatičnimi nihanji morske gladine in globalnimi paleooceanografskimi spremembami. Knjiga je delo s področja regionalne geologije. Besedilo je v angleškem jeziku z izvlečkom v slovenščini.

Karst landforms provide insights into landscape evolution and paleoclimate but are inherently challenging to date. An ancient interval of particularly intense weathering of Western Australian Pleistocene aeolianites is recorded in a spectacular pinnacle karst landscape with associated ferricrete nodules. (U-Th)/He dating of the ferricrete nodules revealed an age of 102.8 + 10.6/−11.4 thousand years, corresponding to marine isotope stage 5c. The (U-Th)/He age thus directly dates the wettest interglacial period in the region over the last 500 thousand years, which was responsible for the dissolution that formed the pinnacles. The reliability of the ferricrete (U-Th)/He age is supported by bounding optically stimulated luminescence and U-Th dates on associated aeolianites and carbonate precipitates, respectively. A (U-Th)/He approach is globally applicable to aeolianites with associated ferricretes, allowing more accurate dating of the environmental changes affecting these lithologies, and temporally constraining rapid Pleistocene climatic oscillations to better contextualize the associated evolution of the biosphere.

We present a geomorphological map on a scale of 1:15,000, with detailed sedimentological descriptions, and a general relative spatio-temporal depositional reconstruction of Quaternary sediments in the Planica-Tamar Valley (NW Slovenia). After the Last Glacial Maximum, the retreating Quaternary glacier deposited large amounts of glacial sediments. These were followed by Holocene sediments, which differ in their sedimentological characteristics, transport mechanisms, and morphology. These sediments are deposited as sedimentary bodies with complex depositional geometries. They form areas of active, partly active, and inactive sedimentation in response to local/regional climate and bedrock geology. Previous research of the valley was mainly focused on bedrock mapping, while almost completely neglecting Quaternary deposits. This work is the first broader analysis of Quaternary sedimentary deposits in the research area, which offers an insight into the complex geomorphological and sedimentological processes, which shape the current mountainous landscape.
