Field mapping of buried faults : a new approach applied in the Western Carpathians

Marko F., Dyda M., Gajdoš V., Rozimant K., Mojzeš A.

Geological Quarterly

35--46

Fault array in an area covered by Quaternary sediments and deprived of bedrock outcrops was investigated using fault trace mapping by geophysical methods and human feedback information from dowsing. The tectonics in the study area is dominated by a ENE-WSW fault zone affecting regional-scale structures. The fault network was approximated by dowsing-enhanced mapping and subsequently confirmed by field geophysical measurements using electromagnetic and radon emanometry methods. A resultant detailed map of structural discontinuities highlighted that combined dowsing and geophysical survey is an effective and reliable tool to identify buried faults. This approach with its low costs and fast field recognition is highly recommended for construction-work planning and for mineral resources exploration and exploitation.

Alpine regional metamorphism of Föderata Group metacarbonates (southern Veporicum, Western Carpathians, Slovakia): P–T conditions of recrystallization

P-T conditions of the Alpine regional metamorphism of carbonate successions which form the cover sequence of the southern Veporicum crystalline basement have been determined. The P-T estimates were calculated on the basis of microprobe chemical analyses of equilibrium mineral assemblages together with analyses of bulk rock chemical composition. The calibrated geothermic reactions Cal-Dol and Kfs-Phl were used. Geothermometric and geobarometric data were obtained using the SOLVCALC, TWQ and PERPLEX software programs in combination with phengite geobarometry. The metacarbonates were formed from a sedimentary-carbonate protolith in low-pressure and low-temperature conditions of greenschist facies in the kyanite stability field: TCalAb-Or
