A funnel shaped karst depression - sinkhole - from Vajarska hill (Male Karpaty Mts.) filled by two generations of paleokarst sediments is analysed. The first generation of fill is formed by a red clay of the "terra rossa" type with kaolinite dominant, the second generation of fill is formed by a light ochre silt, in which the dominant mineral is quartz. Both generations of fill represent allochthonous sediments, redeposited from weathering crusts on alkaline eruptive rocks and crystalline shales. They were caught in the sinkhole and other paleokarst depressions as in traps.
