Absolutely metal and plastic decompose and break down, respectively.
- inglor_cz 3y agoNot all metal. Buried gold retrieved from ancient graves looks very "fresh".
- jiggawatts 3y agoAlso most of the noble metals would remain pristine: platinum, iridium, etc…
- MichaelZuo 3y agoAfter ten million years even a large gold ingot would entirely be subsumed by the surrounding matter. Assuming a 10 nanometer/year erosion.

- userbinator 3y agoThe latter, back into oil.
- thrashh 3y agoSure, but on very long timescales. And eventually once you make enough of it, it gets lodged in all sorts of places, some less susceptible to decomposition, such as humans in bogs or mammoths in glaciers. I just find it hard to believe there to be not a single trace of anything.
