| Tiny crystals of hematite, goethite, chalcopyrite, marcasite, and dolomite are common and make excellent micromounts. |
| Most, if not all, of these mines have likely produced specimen-quality hematite, goethite, and perhaps other minerals. |
| Impressive blades and masses of lustrous micaceous hematite occur in localized quartz veins, and reniform goethite is found in the walls. |
| Like hematite, some goethite is pseudomorphic after a rhombohedral carbonate mineral. |
| Microcrystals of azurite and goethite and a small number of microcrystals of chalcocite were also recovered. |
| These soils have a typical, immature tropical soil mineral assemblage dominated by kaolin, quartz and goethite. |
