Rh mineral's
TīmeklisAbstract. In the preceding chapters I have discussed, what I would consider main-stream hydrothermal systems responsible for a wide range of ore deposits. In this section, I discuss a range of hydrothermal mineral systems, for which a link with magmas or magmatic activity is either missing or uncertain, hence the title of this chapter.
