Other than radiation, fusion, and fission, are there any natural processes which alter atoms from one element to another? [Chemistry]

Fission and fusion are not the only kinds of nuclear reactions that happen in nature. There are *many* more, and many of them will turn the reactants into different elements.

For example, capture reactions, knockout reactions, transfer reactions, spallation, etc.
