  • The anatomy of Ni-Cu deposits: from staging chamber to chonolith

    • Physical processes are the key processes in the generation of giant Ni-Cu deposits.
    • Chemical processes are merely Step 1 in forming mineralization - it is not the ore formation  process.
    • Remember unlike hydrothermal ore deposit Ni sulfides...
