Copper Silicate Gel, Formation, Kipuka Kanohina Cave System, Hawaii County, Hawaii 1
"the blue-green coating is a nearly pure copper silicate. However, because it is noncrystalline,
it is technically not a mineral. The infrared spectrum (Fig. 11) shows that the phase is highly hydrated, so it can be best described as a copper silicate gel. The chemical composition is similar to chrysocolla, (Cu,Al)2H2-Si2O5(OH)4?nH2O, but lacks crystallinity." This excerpt is found in an article by William B.
