Microcrystals of azurite and goethite and a small number of microcrystals of chalcocite were also recovered. |
Like hematite, some goethite is pseudomorphic after a rhombohedral carbonate mineral. |
Most, if not all, of these mines have likely produced specimen-quality hematite, goethite, and perhaps other minerals. |
Also associated with smoky quartz are microcline, fluorite, goethite, and topaz. |
Impressive blades and masses of lustrous micaceous hematite occur in localized quartz veins, and reniform goethite is found in the walls. |
Microcrystals of pyrrhotite, goethite, pyrite, galena, and calcite are found on the dumps. |
