- A small amount of sulfur-containing raw magnetite ore (chlorite - serpentine - magnetite, pyroxene - amphibole - the illusion of goethite - magnetite, calcite - magnetite ore, etc.)

-Small amounts of sulfur-containing magnetite ore of original (chlorite-serpentine-magnetite and pyroxene-amphibole-magnetite-illusion of goethite, calcite-bearing magnetite ore, for example)

- Contains the few sulfur primitive magnetite ore (green mudstone - serpentine - magnetite, pyroxene - amphibole - pseudomorph goethite - magnetite, calcite - magnetite ore and so on)
