Truncated Epikarst on Glaciokarst

The relationship between the epikarst and feature development was studied on glaciokarsts with the use of the resistivity of the profiles of VES measurements and the characteristics of suffosion dolines. It can be established the averages of bedrock resistivity are mostly large both by profiles and areas, but the largest resistivity differences are also large by profiles and areas too. Taking into consideration resistivity values on glaciokarsts, below a thinner superficial deposit, both recent epikarst and paleoepikarst occur, while below a thicker superficial deposit, only paleoepikarst can be found. Large resistivity values refer to the low degree of the cavity fill of the paleoepikarst, to the deep position of the piezometric level, while large resistivity differences indicate the heterogeneous character of the cavity formation and the different degree of denudation of the epikarst. Low resistivity values refer to the immaturity of recent epikarst, while in the case of paleoepikarst, they indicate that the cavities are filled. Subsidence dolines have a small diameter because the degree of cavity formation is low in the epikarst. Doline density decreases by resistivity increase. The weak and uneven degree of cavity formation can be explained by the partial denudation of the epikarst (which may have continued its development below the ice) that developed preceding the glacials.
