A Study of the Dětaň Locality (Oligocene, Doupovské hory Mts. Volcanic Complex, Czech Republic): Collection of Field Data and Starting Points for Interpretation.

Popis výsledku v původním jazyce

During the Early Oligocene, a limiting factor for subaerial vegetation at southern margin of the Doupovské hory Mts. was a repeated fall of basaltic tuffs. Because no tuff level provided a record of pedogenesis, intervals between the eruptions must havebeen very short (tens of years at maximum). Subsequently, the locality was lying on a flood plain of a watercourse bringing volcanic material; at that time, the ecosystems were at least twice destructed by pyroclastic flows, which left violet, sharply bounded strata. The age of the basaltic lava flow overlying the tuffs and tuffites was determined by K/Ar method (bulk sample) at 32.6+-1.7 Ma. According to relative paleontological dating, the locality belongs to mammalian Zone MP 21. These data point tothe conclusion that all the volcaniclastic series appeared in a relatively short time in the Early Oligocene.
