ResumoAbstract. New IMA CNMNC guidelines were established for minerals crystallizing on burning coal dumps. These phases are now acceptable as minerals, if it can be proven that the fire responsible for the formation of these phases is the result of natural events. In that case, these substances have to be treated as normal new mineral species, and their complete characterization has to be submitted to the CNMNC via the new mineral proposal form. The authors are specifically asked, however, to give strong arguments in the proposal clearly demonstrating the non-anthropogenic origin of the burning process.
