Natural occurrence & production

The creation of an element’s nuclei and its concentration into terrestrial deposits are different processes. The occurrence note below concerns its presence or production on Earth; it is not a complete account of nucleosynthesis.

“Palladium has been found uncombined in nature, in Brazil, but most is found in sulfide minerals such as braggite.”
