  • porosity, brecciation, slumping, and solution collapse

Comments on the geologic information

  • Octahedral casts of marcasite and chalcopyrite were once deposited upon earlier octahedral galena now completely removed by dissolution and that especially rich nearby portions of the orebodies may have developed through the redeposition of that lead in the form of younger cubic galena (Paalberg and Evans, 1975 ).
