Summary
[edit]DescriptionCracked open cave blisters from Provalata Cave.JPG |
Македонски: Пештерските плускавци се хемисферни испупчени пештерски украси формирани од капиларна вода под притисок, хранета од отвор на ѕидот, започнувајќи со мала пупчеста форма при што наталожената кора е постепено оттурнувана од ѕидот со последователната кристализација. Во Провалата, пештерските плускавци се со димензии од неколку сантиментри, изградени од гипс, но веројатно и други минерали, наталожeни при испарувањето на доводната капиларна вода, при што хетерогеноста на минералниот состав е делумно причина за отворањето (распукувањето) на плускавците. English: Cave blisters are hemispherical bulged speleothems formed by a capillary water under pressure fed from an orifice in the wall, starting from a small bud with the encrustation being forced away from the wall by subsequent crystallization. In Provalata Cave they are few centimeters in size, built of gypsum, and probably other minerals, deposited due to evaporation of the feeding capillary water, with the mineral heterogeneity partly responsible for the cracking open of the blisters. |
