The most characteristic landforms of the Aggtelek Karst Region are the followings : a. karstic microforms : free karrs, covered karrs ; b. landforms of the karstic water conduit : sink holes, dolines of solution, uvalas, karstic dry valley with row
of dolines, draining, erosional (tectonic) karstic gorges and gullies ; c. intrinsic ensembles of landforms : karstic plateaus (planinas). - (ZK)
In this paper, a model is presented by the authors which is suitable to explain a wealth of landforms by the specific way of karstification of the bedrock. Opposite to the karstification of limestone resulting in relief dissection, karst processes
in the dolomite produce superimposing residual surfaces and, after the stoppage of the retreat, conservation of these landforms. - (ZK)

In this paper karr landforms typical for dolomite surfaces were investigated by the authors using methods of field observation, mapping and morphological analysis. Through the mapping of these landforms and of the subsurface bedrock, data were
obtained about mechanisms of formation and factors influencing the process. Observations were made on the circumstances of the occurence of conspicuous karr forms, and recommendations were put forward related to landform protection and nature conservation
Gypsum ; Karst ; Karsticlandform ; Moldavia ; Romania
In the Tazlău Subcarpathians, that lies in the Moldavian Subcarpathians, there are some area rich in gypsum deposits. The main landforms related to these deposits are dolines, lapies, swallets and two little caves. - (M. Vârlan).
Sandstone dissolution landforms in the Furnas Formation, Southern Brazil
of subterranean erosion are the result of kaolinite dissolution, which intensifies along structural directions, in a region of scarped relief and steep hydraulic gradient. As a consequence, the Furnas Formation displays landforms that are characteristic of a both
For the first time a large-scale geomorphological mapping had been carried out in the course of search for placers| karst landforms and deposits filling karstic hollows were studied, their relative age was determined. Three stages in karstification
are distinguished : the Late Miocene-Pliocene, the end of the Pliocene-beginning of the Pleistocene, second half of the Pleistocene, a noticeable deceleration in the process having been traced throughout of the Late Cenozoic. Only karstic-erosional network develops
progressively since the Early Pleistocene. Under conditions of limited water supply the conditions do not favour the heavy minerals concentration and placers formation within the karstic-erosional network. - (L'Ed.).
The Burren in County Clare, western Ireland, is a glaciated karstic landscape with a fragmented soil and vegetation cover on a predominantly limestone substrate. A representative area was studied in order to determine the distributions of soil types
confirm this division and also reveal soils of mixed composition and a distinctive subtype of granite-bearing soil that occurs exclusively on drumlin-like landforms.
