| TiO2 - Occurs as honey-colored mm-sized crystals with complex terminations exhibiting alternating sets of tetragonal bipyramidal faces. |
| CuFeS2 - Occurs as beautiful terahedra to about 1 cm in a brecciated zone. |
| Fe endmember chlorite - (Fe,Mg)3Fe3(Si,Al)4O10(OH)8 - Occures as mm-scale dark green books of micaceous crystals and as micro-inclusions in quartz crystals. |
| Cu2H2Si2O5(OH)4 - Occurs within oxidized (supergene) zone as bright blue to green botryoidal fillings within small cavities. |
