KARSTIFICATION

Fig. 7. Simple chimney (a) in doline-with-ponor G-5/a, composite chimney (b) in doline-with-ponor Ho-1 (Homód-árok area) and truncated chimneys in the Gyenespuszta cave (c) and Cseresi-zsomboly aven (d) (surveyed by KÁRPÁT 1977, figures b, c and d are from Reports for 1978, 1979 and 1984 of Cholnoky J. Caving Group) Legend: 1. dip of enclosing rock; 2. enclosing rock; 3. soil, debris and other redeposited sediment; 4. dolinewith-ponor; 5. chimney (section) formed along bedding plane; 6. chimney section formed along fracture; 7. blind chimney The above outlined origin of chimneys is evidenced by the following observations: - chimneys form where bedding planes or fractures intersect with the surface (surface waters infiltrate and dissolve along these surfaces); - the spatial pattern of chimneys is adjusted to the spatial pattern of fractures and stratification (when eroded, for example, there would be no alternation of sections formed
