This paper presents the bulk geochemical data measured on core samples collected from borehole Diosviszlo Dv-3 (Upper Carboniferous Teseny Sandstone Formation, Slavonian-Drava Unit, Tisza Megaunit, SW Hungary). On average, analysed samples are slightly enriched in Si02 and they have similar K2 0 , Rb, Ba, Th and U abundances to the Upper Continental Crust (UCC). Samples are strongly depleted in MnO, CaO, Na 2 0, Sr and Pb, and they are slightly depleted in Ti02 , A1203, FC1O3 , MgO and P2 0 5 relative to the UCC. In general, the concentrations of both the high field strength elements and the transition trace elements are lower in Teseny sandstones from borehole Dv-3 compared with those of UCC. Total REE concentrations are lower than in the UCC, but chondrite-normalized patterns display the typical LREE-enriched pattern of UCC. These trends can be explained by a sedimentary system dominated by detritus derived from recycled upper crustal material. In addition, chondrite-normalized REE patterns, high Th/Sc, La/Sc and La/Yb ratios, low Cr, V and Ni contents and result of the Ti02 -Ni diagram indicate that these rocks were sourced dominantly from felsic magmatic rocks. The La-Sc-Th and Th-Sc-Zr/10 ternary diagrams of the Upper Carboniferous sandstone samples are typical of continental island arc/active continental margin tectonic settings.
