Sažetak
Sub-millimeter size glass spherules found in Pleistocene glaciogenic sediments at three localities in coastal Dinaric Mts. are transparent, almost perfect spheres, sometimes also fused and spherical. Though most spherules occur free, some also occur imbedded in yellow amorphous matrix. Their chemical composition is compared with published compositions of Eocene flysch and Pleistocene loess from Adriatic localities and shows closer affinity to Pleistocene loess, which could have been their parent lithology. The studied Pleistocene glass spherules are interpreted as distal impact ejecta formed by an asteroid impact into sedimentary target. Compositional affinity of glass spherules with Pleistocene loess suggests that the impact occurred into loess-like target, very likely in early Pleistocene.
