“…As the solution residues are characterized by a high content of iron bearing minerals (Vavliakis, 1981;Williams, 2004;Ford and Williams, 2007;Ćalić, 2011), we applied a semi-automatic data analysis method using the ENVI software to identify the karst-indicating variables associated with iron oxide-rich sediments. Subsequent to image mosaicking, a spatial subset corresponding to the specific area of interest was extracted in order to reduce the data volume and to facilitate further processing.…”

“…In addition, many depressions are frequently filled with colluvial sediments up to several meters thick that obstruct their direct detection. As the solution residues are characterized by a high content of iron bearing minerals (Vavliakis, 1981;Williams, 2004;Ford and Williams, 2007;Ćalić, 2011), we applied a semi-automatic data analysis method using the ENVI software to identify the karst-indicating variables associated with iron oxide-rich sediments. In detail, we used the Spectral Angle Mapper (SAM), which is an automated classification procedure to compare image spectra to known spectra.…”

We present an integrated study of subsurface and surficial karst landforms to unravel the uplift history of karst landscape in a tectonically‐active area. To this end, we apply a multidisciplinary approach by combining cave geomorphology and Th/U dating of speleothems with remote sensing plus geophysical imaging of surface landforms. We use as an example Mt. Menikio in northern Greece where four caves share well‐defined epiphreatic/shallow phreatic characteristics that are related to the distribution of surface and buried doline fields and provide evidence for three distinct water table stillstands (e.g. expressed as cave levels) now lying at ~130 m, ~800 m and ~1600 m a.m.s.l. Our dating constraints delimit the age of the lower water table stillstand prior to 77 ka ago and imply a maximum rate of relative base level drop of 0.45 mma‐1, which is consistent with relative tectonic uplift rate estimates along currently active normal faults. We interpret the elevation of the higher water table stillstands to reflect earlier phases of uplift related to the regional tectonic events associated with the development of the North Anatolian Fault and the Northern Aegean area. Our analysis shows that the combined study of epiphreatic/shallow phreatic caves and surficial karst landforms together, is a robust way to investigate the uplift history of a karst landscape in a tectonically‐active setting. © 2019 John Wiley & Sons, Ltd.

We combine geoarchaeological investigations with high-resolution airborne laser scanning (ALS) topographic and airborne laser bathymetric (ALB) measurements to reassess the topography of the Roman city of Apsorus (modern Osor, northeastern Adriatic Sea, Croatia), which has generally been interpreted as important nodal point of Roman maritime traffic. Apsorus is located at the isthmus connecting Cres and Lošinj islands, which is 90 m wide at the narrowest part and dissected by a canal of supposed Roman age. A conspicuous low-lying wetland north of the city has been suggested to be a former sea passage and harbour area. Geoarchaeological coring, sedimentological analysis and radiocarbon dating suggest that this depression was already silted up with terrestrial sediments some 6,000 years ago and, especially in combination with the lower sea-level at that time, could not have been a Roman harbour. The combination of the ALS/ALB topographic data with lower sea-levels reconstructed for the Roman period challenges the traditional view which places ancient Osor on a small island and allows for new interpretations of the accessibility of Osor by sea.

“…Closed depressions, which are characteristic features for Dinaric karst (Mihevc and Prelovšek, 2010), are also present in other karst landscapes that were once glaciated, such as the Julian Alps (Colucci, 2016) and Dachstein Mountains (Veress, 2017) in the European Alps, Picos de Europa (Smart, 1986) and Taurus Mountains (Sarıkaya and Çiner, 2017). These so-called "glaciokarst depressions" (Ćalić, 2011;Veress, 2017), particularly those located at the edge of terminating glaciers and thus experiencing key aggradation phases, are major depocenters for glacigenic deposits in karst areas (Adamson et al, 2014;. As a result, glaciokarst depressions often host valuable proxy-data, which are important sources of information for palaeoenvironmental and palaeolandscape studies.…”

Glaciokarst depressions are major glacigenic depocenters in the Dinaric mountain karst areas and often store important information about the timing and nature of glacial processes and paraglacial sediment reworking. This study focuses on Praprotna draga, which is one of the largest glaciokarst depressions in the Snežnik Mountain (Dinaric karst), with an area of ~3.4 km 2 and a maximum depth of 140 m. The western slopes of the depression are characterized by undulated moraine morphology and alluvial fans are filling its entire floor. We present the results on the thickness, origin and age of the sediment infill using a complementary geomorphological, sedimentological, geophysical and dating approach. Distribution of moraines point to two glacial advances that were associated with two main alluvial fan aggradation phases recognised using the electrical resistivity tomography measurements. The youngest alluvial deposits were sampled for cosmogenic 36 Cl analysis using amalgamated carbonate pebbles. The depth profile of 36 Cl concentrations suggests an age of 12.3 ± 1.7 ka when assuming a likely denudation rate of 20 mm ka-1. Since the existence of the Younger Dryas glaciers in the study area is climatically difficult to explain, we tentatively propose that the youngest alluvial deposition in Praprotna draga took place after the glacier retreat during the paraglacial period. Our findings suggest that the time window of paraglacial adjustment in the Snežnik Mountain was brief and likely conditioned by quick recolonization with vegetation and inefficient surface runoff on deglaciated karst terrain.
