We present new sedimentological, petrographical, palaeontological and detrital zircon U-Pb data on late Oligocene-early Miocene sedimentary rocks of the thinskinned thrust belt of East Carpathians. These data were acquired to reconstruct the sedimentary routing system for two compositionally different turbidite fans made of the regionally extensive Kliwa and Fusaru formations. On the eastern margin of the Moldavides foreland basin, large low-gradient river systems draining the East European Platform provided well-sorted quartz-rich sand forming deltas on wide shallow shelves and thick Kliwa submarine fans. Due to the westward subduction of a thinned continental plate, the western basin margin was characterized by short, steep-gradient routing systems where sediment transport to deep water was mainly through hyperpycnal flows. The Getic and Bucovinian nappes of the East Carpathians and the exhumed Cretaceous-Early Palaeogene orogenic wedge fed Fusaru fans with poorly sorted lithic sand. The Fusaru fans trend northwards in the foredeep basin having an elongate depocentre, interfingering and then overlapping on the distal part of the Kliwa depositional system due to the eastward advance of the Carpathian fold-and-thrust belt. A smaller sediment input is supplied by southern continental areas (i.e. MoesianPlatform, North Dobrogea and potentially the Balkans). In general, the sandstone interfingering between distinct basin floor fan systems is less well documented because the facies would be similar and there are not many systems that have a distinct sediment provenance like Kliwa and Fusaru systems. This case study improves the understanding of regional palaeogeography and sedimentary routing systems and provides observations relevant here or elsewhere on the interfingering turbidite fan systems.

In Romania, it is possible to determine the position of points with the help of real-time GNSS receivers, using the ROMPOS application of the National Agency for Cadastre and Real Estate Advertising through the National Cartography Center. The application is used where there is a signal on the mobile phone and ensures an acceptable accuracy not only in planimetric but also in altimetric positions. Lately, controversies have arisen regarding the accuracy of the results obtained with the help of the ROMPOS application, versus the static method, both horizontally and at altitude. This paper aims to demonstrate that the results obtained with the ROMPOS application fall within the precisions requirements for current works.
