|
| Dimensions: | 7.2 x 8.2 cm |
| Description: |
| A mounded cluster of tightly intergrown fluorite cubes to 2.7 cm. The gemmy, colorless cubes have a silky luster with stepped-growth faces. |

| Neat to see an older Rosiclare District piece! These are incredibly rare to find...this is a nice one. The sphalerite from the Davis-Deardorff is a good example of what was found there post WW II.

Because of the contrast between the Baryte and fluorite this piece was difficult to photograph. I seldom use true backlighting when photographing minerals, but decided it was worth a try in the second photo. It was the only way to show the fluorite crystals that host the Baryte without burning out the light-colored Baryte.
| Mineral: | Barite |
| Locality: | | Annabel Lee Mine, Harris Creek Sub-District, Hardin County, Illinois, USA | |
|
| Dimensions: | 5.5 x 7.0 cm |
| Description: |
| Lustrous, creamy white tabular Baryte crystals on purple fluorite. Mined in 1988. |

Hi Michael.
Do you know if the brownish inclusions in the fluorite sample TN613 are hydrocarbons?

Hi Vinoterapia,
I'm not certain what the inclusions are. My understanding is that the whitish/gray inclusions which form the cubic phantoms are clay. The brown may be clay or something else entirely.
