Mature pseudodepression near karst object Ho-8, karst terrain around Homód-árok (the probably postgenetic karst object Ho-8 is fed by the overflowing water from the neighbouring fossilised depressions; some fossilised karst features - wallows - have an altitude of 447 m, indicating remarkable deepening of the depression floor) Legend: 1. contour line; 2. outcrop of Middle Eocene limestone undifferentiated; 3. cover sediment (delimation is approximate); 4. covered, exhuming cone; 5. exhuming cone; 6. semiexhumed cone; 7. pseudodepression; 8. karst depression (doline-with-ponor); 9. fossilised karst depression (wallow); 10. recharge area of karst object Ho-8; 11. regressional developing superimposed valley; 12. channel in the cover sediments and they cave in. Features of interior drainage, postgenetic dolineswith-ponor develop (Picts. 22,23). Also in this case the catchment of the depressions forms over part of the sediments filling the paleokarst depression. The upper part of the cover sediments of the filled paleokarst depression has undergone repeated redeposition. Locally the neighbouring fossilized ponors represent a single buried landform. The valley floor slopes towards the centre of the depression from all directions. These are essentially double depressions. The gentle outer slope gradually smoothes into neighbouring valley floors and sides. The internal part is not necessarily the postgenetic dolines-with-ponor in the geometrical centre. The outer zone is partly erosional, partly
