Morphoanalysis of bacterially precipitated subaqueous calcium carbonate from Weebubbie Cave, Australia
journal contribution
posted on 2023-05-18, 14:19 authored by Contos, AK, James, JM, Heywood, BR, Pitt, K, Rogers, PIn 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.
