Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).
The Zhuangzi Au deposit in the world-class Jiaodong gold province hosts visible natural gold, and pyrite as the main ore mineral, making it an excellent subject for deciphering the complex hydrothermal processes and mechanisms of gold precipitation. Three types of zoned pyrite crystals were distinguished based on textural and …
Harold, Sorry I didn´t see your comment before now. The question asked was a very general question, but I was actually being serious about my answer.

In the case of gold, after the fluid runs through the rocks, it usually reacts with other surrounding rocks and causes the gold to materialize in cracks and fractures in existing minerals. Other sulfides that can also form inside the quartz, other than gold, are pyrite, arsenopyrite, or chalcopyrite.
Figure 1. This example of Colombian pyrite-containing rock crystal weighs 466.27 ct and measures 61.90 mm in length. Photo by Diego Sanchez. Pyrite and quartz are two relatively common minerals. Transparent colorless quartz, known as rock crystal, is host to a wide variety of mineral and fluid inclusions, more so than any other gem mineral.
