Abstract

In Australia, the karst land referred to as the Nullarbor covers an area in excess of 200,000 km 2 , although in proportion to its area the karst is poor in known caves. Despite being referred to by their collective name, the Nullarbor Caves, many of the individual caves are world class in their own right. In the world of caves, where in most cases biogenic carbon dioxide and surface waters provide the essential ingredients for the solution of limestone and the precipitation of decorations, the more of both, the bigger and more spectacular the caves. The Nullarbor Caves provide an example of how caves can originate, enlarge, and become decorated with speleothems at times when there is a shortage of both.

3. Morphoanalysis of Bacterially Precipitated Subaqueous Calcium Carbonate from Weebubbie Cave, Australia

Abstract

In this article, we present a previously unreported morphology of bacterially precipitated calcite (determined using XRD, FTIR, and SAED) occurring subaqueously in Weebubbie Cave. Observations using FESEM and TEM revealed spindle-shaped crystals with curved {hk.O} faces lying parallel to the c-axis. Calcite precipitated under conditions designed to mimic the inorganic solution chemistry of the cave revealed a different morphology. These differences between the crystals suggest that the formation of the cave crystals is a consequence of biologically activity.

Abstract

The nature of unusual aquatic microbial formations in flooded passages of cave systems in the Nullarbor region of Australia was investigated using electron microscopy and DNA analysis. The caves are located in a semiarid region but intersect the watertable at depths of approximately 100 m below the surface. Throughout submerged portions of the caves divers have noted the presence of unusual microbial formations. These 'microbial mantles' comprise sheets or tongues of mucoid material in which small crystals are embedded. Examination of the biomass revealed it to be primarily composed of densely packed, unbranched filaments, together with spherical-, rod- and spiral-shaped cells, and microcrystals of calcite in a mucoid matrix. Molecular phylogenetic analysis of the community structure revealed approximately 12% of clones showed high similarity to autotrophic nitrite-oxidizing bacteria (Nitrospira moscoviensis). The remainder of the clones exhibited a high proportion of phylogenetically novel sequence types. Chemical analysis of water samples revealed high levels of sulphate and nitrate together with significant nitrite. The community structure, the presence of nitrite in the water, and the apparent absence of aquatic macrofauna, suggest these microbial structures may represent biochemically novel, chemoautotrophic communities dependent on nitrite oxidation.
