Patterns of Collapse Chambers in the Endokarsts of Mallorca (Balearic Islands, Spain)

Abstract

Prispevek podaja pregled razporeditve podornih dvoran na krasu Mallorce. Na načrtih mnogih jam je mogoče razločiti enostavne podorne dvorane in vrste velikih jamskih prostorov, eno glavnih sestavin tamkajšnjih jam, kar kaže na velik pomen teh dveh elementov. Za opis in boljše razumevanje razporeditve udorov so lahko zelo koristni podatki, pridobljeni s pomočjo podrobnega kartiranja različnih podornih struktur, kot so podorni stožci, nagnjena podorna pobočja, prerezi v obliki obokov, »stičišča«, podorni zamaški in kupolaste strukture.

A general overview on the patterns of collapse chambers in the karsts of Mallorca is presented. The great significance of single breakdown chambers and strings of large rooms as one of the major constituents of cave patterns is easy to recognize in the cave surveys of many Majorcan caves. Detailed mapping of several collapse features such as breakdown piles, sloped boulder floors, vault profiles, coalescence areas, boulder chokes and dome structures can yield useful information regarding description and better understanding of cave collapse patterns.
