ND7-RVMMercury : Hg

Multiple photos available
El Entredicho Mine, Almadenejos, Almadén District, Ciudad Real, Castile-La Mancha, Spain

Field of View: 9 mm

There is obviously cinnabar included in the quartz, and the quartz is swarming with mercury inclusions up to a few microns wide. There is also abundant, very lustrous pyrite on the specimen.

1CE-UGHMonazite-(Ce) : Ce(PO4), Cassiterite : SnO2

Multiple photos available
Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia

Field of View: 5 mm

The monazite is orange-pink under halogen light; under some fluorescent bulbs it is a pale lemon yellow. Quartz is also in the field of view.

6X2-XNTXenotime-(Y) : YPO4, Cassiterite : SnO2, Monazite-(Ce) : Ce(PO4)

Multiple photos available
Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia

Field of View: 8 mm

The cassiterite, and to a lesser extent the xenotime, monazite, and quartz, has a thin white coating that may be similar to diadochite. Iridescent contact scars on cassiterite mark where other crystals have been plucked off.

XV5-TP9Chalcocite : Cu2S, Digenite : Cu1.8S

Multiple photos available
Manto Cobriza Mine, Copiapó, Copiapó Province, Atacama Region, Chile

Field of View: 6.5 mm

With nicely terminated calcite prisms. About 25% of the chalcocite is iridescent and often pitted; the iridescence may be like that on chalcocite at the Tongshankou Mine. In most cases the iridescent chalcocite appears to be older.

The digenite, perched on a large iridescent patch, is visually identified from crystal form, twinning, and color. There is usually one of these digenite twins, about 2 mm wide, on each large chalcocite group.

XV5-TP9Digenite : Cu1.8S, Chalcocite : Cu2S

Multiple photos available
Manto Cobriza Mine, Copiapó, Copiapó Province, Atacama Region, Chile

Field of View: 6 mm

With nicely terminated calcite prisms. The digenite, perched perfectly on top of the chalcocite group, is visually identified from crystal form, twinning, and color. There is usually one of these digenite twins, about 2 mm wide, on each large chalcocite group.

About 25% of the chalcocite is iridescent and often pitted; the iridescence may be like that on chalcocite at the Tongshankou Mine. In most cases the iridescent chalcocite appears to be older.
