Microcrystals of pyrrhotite, goethite, pyrite, galena, and calcite are found on the dumps. |
The primary ore minerals were not investigated, although galena and pyrite were found as relict masses on several occasions. |
The pods were composed of large masses of black sphalerite containing vugs of petzite on gold, galena, rhodochrosite, chalcopyrite, and pyrite. |
Similarly, silver has been described replacing a variety of silver minerals, pyrite, and galena. |
This karsting provides highly permeable rocks in which the sulphide minerals sphalerite and galena represent the valuable mineralization. |
On the dumps I found galena, pyrite, and rugs full of quartz, dolomite, and a few tiny, water-clear fluorites. |
