Conclusions

The available data, although insufficient to understand the complete process of ore formation, give some support to the preliminary results on fluid behavior in the hydrothermal system of Dajishan:
  1. 1.

    Several successive fluids have crystallized minerals, using the same veins as channels.

     
  2. 2.

    A single vein network, or even the complete vein system, can be considered, in a first approach, as an infinite medium (i.e., an open system) relative to the studied elements.

     
  3. 3.

    Precise observations indicate the existence of several differenciation processes in the main fluid stage which occurred during ore deposition. Their interpretations—“immobile” fluid and diffusion or ascending fluid and crystallization or mixing—remain uncertain until new data on other minerals are obtained.
