How to Test a Rock for GoldSciencing

Real gold also leaves a gold streak when scratched against a small bit of unglazed ceramic, like the back of a piece of bathroom tile, but iron pyrite leaves a greenish black colored streak. In your gold hunting kit, a small, piece of glass and a bit of unglazed tile can help you identify real gold in a flash.

Mechanisms Determining the Structure of Gold Catalyzed GaAs ...

The evolution of polytypism during GaAs nanowire growth was investigated by in situ X ray diffraction. The growth of nanowires was found to start with the formation of zincblende structure, followed by the growth of wurtzite structure. The growth process was well reproduced by a simulation based on a layer by layer nucleation model. The good agreement between the measured and simulated results ...

Gold: The mineral native Gold information and pictures

Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is.
