From: Biologically induced mineralization of dypingite by cyanobacteria from an alkaline wetland near Atlin, British Columbia, Canada

Figure 1

A: A photograph showing the underside of a benthic microbial mat found in the wetland. B: A film of nesquehonite on the wetland water surface. C: A light micrograph of the benthic microbial mats showing filamentous cyanobacteria, Lyngbya sp., and unicellular green algae. D: A second light micrograph of the microbial mats with a large crystal of nesquehonite that likely formed after sample collection. E: A SEM micrograph of flakey dypingite associated with filamentous cyanobacteria, which along with aragonite, constitutes the majority of the microbial mat material. F: Radial collection of nesquehonite crystals precipitated in a carbonate film on the water surface.
