Geologic maps generally appear complex and daunting, and certainly some are. However, many have information hidden within their bright splashes of colors and patterns that can aid the prospector who takes the time to study them.
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
