It is these minerals that make studies of the provenance (origin of the grains) possible in the study of sandstones.

How do you tell if a rock has gold in it?
One of the easiest and most telling tests for gold that you can perform on your rock is for hardness. This test is an application of Mohs hardness scale, which compares the hardness of different minerals by scratching them against one another.
How deep is gold found in the earth?
There is no specific depth at which gold can be found. Examples of this are the Welcome Stranger – the largest gold nugget ever found – which was retrieved at only 3cm (1.18in) below the surface. Oppositely, gold mining operations today take place at a depth of around 3km (1.8 miles) under the Earth’s surface.
How can you tell a rock is gold?
You’re looking for a scratch on the glass. If the glass gets scratched from the ‘gold’, it’s not actually gold. Since glass has a hardness of around 5.5 it will only be scratched by harder minerals like pyrite and quartz. If the glass doesn’t scratch then that’s a great sign – you likely have gold in your rock!
