Zn concentration and isotope chart and hydrozincite photomicrograph

Detailed Description

A) Concentration and Zn isotope signature of water in the Rio Naracauli as a function of distance downstream. As hydrozincite precipitates, favoring the heavier isotope of Zn, both the Zn concentration (open symbols) and the value of δ66Zn (solid symbols) decrease. B) Photomicrograph of hydrozincite forming on the surface of bacterial exopolysaccharide secretions.
