Relationships between cave dimensions and local catchment areas in Central Scandinavia: implications for speleogenesis
Abstract:
The caves formed in the Caledonide metalimestones of Central Scandinavia are identified as occurring in three cave hydrological classes that are randomly intermingled with each other both geographically and altitudinally: relict, mainly vadose (MV) and combination caves. The morphology of the relict caves shows that they were enlarged phreatically. Their dimensions of length, cross-section and volume are unrelated to their local catchment area, whose mean size is only 2.6km2. Indeed, large relict caves may be found near ridge tops, and their mean cross-section to catchment area ratio (XS/CA) is as large as 20.3m2km-2. MV caves contain active stream passages and sumps without significant phreatic upper levels or passages. Although there is no simple relationship between their mean dimensions and their local catchment area, which has a mean size of 4.7km2, their mean XS/CA ratio is only 2.8m2km-2. However, their maximum dimensions are constrained by the logarithm of catchment area. The combination caves contain relict phreatic (and, more rarely, relict vadose) passages that lie above an active vadose streamway and they have mean dimensions significantly larger than those of both relict and MV caves. Their mean CA is 4.6km2 (close to that of the other active cave class) and their mean XS/CA ratio is 11.6m2km-2, which is intermediate between relict caves and MV caves. These observations suggest that the active vadose passages developed during the present conditions of the Holocene, with dimensions related to the flow-rates of present allogenic recharge, as supported by likely entrenchment and waterfall recession rates. In contrast, the relict phreatic passages probably enlarged when the caves were submerged by flowing glacial meltwater that was less related to present catchment area, during a previous deglaciation phase. Most relict caves and the whole set of MV caves seem to have each separately experienced only one phase of cave enlargement after inception, with phreatic development favoured at valley shoulder and ridge cave locations and vadose development favoured at valley floors with large catchments. The larger dimensions and greater complexity of the combination caves indicate that they are more representative of the full range of enlargement opportunities that were available during the evolution of their local topography during one or more full cycles of glaciation, deglaciation and interglaciation.
