That meander is 1. overdeveloped and selfexaggerated bend is a stream course either on the surface or underground, caused by more erosion on the outside than on the inside of a bend due to natural wash of the flow. undergound meanders commonly originate within bedding plane guided elements of the phreas, where a single dominant tube has gathered drainage from the surrounding area. following uplift and the onset of vadose conditions any stream that utilizes the meandering tube incises rapidly and the imposed meander course is entrenched into the underlying rocks. such incision or entrenchment produces characteristic tall, narrow, twisting vadose canyons, to such an extent that the french describe them as 'meandres'. canyons may meander more at their lower levels, due to enlargement during incision [9]. 2. a looplike bend in a river due to lateral erosion activities [16]. 3. in a cave, an arcuate curve in a channel formed by lateral shifting of a cave stream [10]. see ceiling meander; meander niche.?

Unique iron-manganese colonies of microorganisms in Zoloushka Cave (Ukraine-Moldova)
Abstract:

During open-pit quarrying and related lowering of groundwater level in the gypsum karst aquifer (since 1950), large cave Zoloushka became accessible for direct exploration, in which considerable geochemical transformations of environment occurred, accompanied by the formation of specific deposits, as well as by burst of microbial activity. Among microorganisms, some of the most active were various iron bacteria. Microbial activity has resulted in precipitation of black and red biochemical formations – microbialites (coatings, crusts, films, stalactites, stalagmites, etc.), which cover walls and floors of cave passages. Most interesting among the microbialites are iron-rich colonial formations of various shapes (stalagmite-like, tube-like, coral-like, etc.) formed by yet unidentified fungi-like microorganisms which likely are new to science. In this paper, we characterize occurrence and morphology of the colonial aggregates, morphology and chemical composition of microorganisms  and develop working hypotheses of their identification.
