LP5-07PCalcite : CaCO3, Marcasite : FeS2, Chalcopyrite : CuFeS2, Dolomite : CaMg(CO3)2

Sweetwater Mine, Ellington, Viburnum Trend District, Reynolds Co., Missouri, USA

Dimensions: 18.5 cm x 11 cm x 1.5 cm

Calcite on marcasite and chalcopyrite with minor dolomite from the Sweetwater Mine, Reynolds Co., Missouri. This one is dated 1974 and is notable for the presence of both pink and green inclusions, likely alterations of chalcopyrite and siegenite (cobaltoan calcite and malachite is a possibility). Specimens like this also came out between 2007-2009, possibly from returning to collect at the original location. Without oxidation, the entire matrix would be gold in color. Green and especially pink inclusions are relatively uncommon for Sweetwater and very rare for the Viburnum Trend in general.

HPH-10WCalcite : CaCO3, Dolomite : CaMg(CO3)2, Chalcopyrite : CuFeS2

Sweetwater Mine, Ellington, Viburnum Trend District, Reynolds Co., Missouri, USA

Dimensions: 7.5 cm x 4.2 cm x 4 cm

This small crystal from Sweetwater Mine is heavily etched, something I occasionally see from the Viburnum Trend, but this is my first specimen from Sweetwater that is etched like this.

PCQ-LCACalcite : CaCO3, Chalcopyrite : CuFeS2, Dolomite : CaMg(CO3)2, Quartz : SiO2

Sweetwater Mine, Ellington, Viburnum Trend District, Reynolds Co., Missouri, USA

Dimensions: 12.5 cm x 8 cm x 4 cm
Largest Crystal Size: 8.5 mm

A great group of prismatic crystals from the Sweetwater Mine. The large DT crystal in the foreground is in perfect condition. What there is to note about this one is the luster and transparency, which is more common in smaller crystals, but here we see good clarity in an 8.5 cm crystal. Looking closely, the matrix has a generation of quartz on which iridescent chalcopyrite and white dolomite rhombs formed.

TM2-D2PCalcite : CaCO3, Dolomite : CaMg(CO3)2

Sweetwater Mine, Ellington, Viburnum Trend District, Reynolds Co., Missouri, USA

Dimensions: 9.5 cm x 8.5 cm x 7.5 cm

Transparent yellow calcite crystals with internal scalenohedral phantoms inside on a dark dolostone matrix. Collected in the '70s or '80s from Sweetwater Mine.

AKR-G6VCalcite : CaCO3, Quartz : SiO2, Galena : PbS, Marcasite : FeS2

Casteel Mine, Bixby, Viburnum Trend District, Iron Co., Missouri, USA

Dimensions: 10 cm x 5.4 cm x 6 cm

Milky white calcite crystals rests on a matrix composed mostly of galena coated with quartz. When viewed from the back much of the galena is octahedral and has areas where marcasite is present between the quartz and the galena. Combinations with quartz are common from Casteel Mine.

EHC-8KKCalcite : CaCO3

Williamson Co., Texas, USA

Dimensions: 9 cm x 6 cm x 4.3 cm

Collected in April of 2018 from a newly discovered (April) creek bed deposit near Hutto, Williamson Co., Texas. All of the calcites so far from this locality show a significant amount of natural etching, making some of the specimens look like melting ice. The specimens are dug from mud close to or at the water table and most have been detached from any matrix that may have been present in the past. Most show no "fresh" cleaving as every surface is affected by the etching. Crystals from the locality range in size from about 3cm to 20cm. Scalenohedral crystals are the most common, but there are some rhombs as well, often attached to a scalenohedron. Single crystals, pairs, double terminated crystals, and clusters have been found, there were even a few possible twins. Some of the specimens exhibit interesting "cross hatching" patterns on the surface that in some cases is so heavy that those parts of the crystal look like the pages of a book. About 200 specimens were dug out. Crystal color is white to straw yellow, to a light honey color.

This specimen is a pair of scalenohedrons etched smooth all around like melting ice. One termination is either cleaved and re-healed or etched like that.

917-HFACalcite : CaCO3

Williamson Co., Texas, USA

Dimensions: 10.5 cm x 9 cm x 9 cm

Collected in May of 2018 from a newly discovered (April) creek bed deposit near Hutto, Williamson Co., Texas. All of the calcites so far from this locality show a significant amount of natural etching, making some of the specimens look like melting ice. The specimens are dug from mud close to or at the water table and most have been detached from any matrix that may have been present in the past. Most show no "fresh" cleaving as every surface is affected by the etching. Crystals from the locality range in size from about 3cm to 20cm. Scalenohedral crystals are the most common, but there are some rhombs as well, often attached to a scalenohedron. Single crystals, pairs, double terminated crystals, and clusters have been found, there were even a few possible twins. Some of the specimens exhibit interesting "cross hatching" patterns on the surface that in some cases is so heavy that those parts of the crystal look like the pages of a book. About 200 specimens were dug out. Crystal color is white to straw yellow, to a light honey color.

This specimen is a cluster of scalenohedrons featuring deep cross-hatching grooves and the presence of plant roots. All surfaces naturally etched from ground water to a waxy luster. One 4.6 cm DT crystal can be seen in the foreground and is heavily cut through with the cross-hatches that follow cleavage planes.

UY9-159Calcite : CaCO3

France Stone Co. Quarry, Bellevue, Sandusky Co., Ohio, USA

Dimensions: 5.7 cm x 3 cm x 3 cm

This calcite from Bellevue Quarry is very transparent for its size. This crystal is large for the locality and was collected sometime in the 1970s.

1WV-AVTCalcite : CaCO3, Dolomite : CaMg(CO3)2, Galena : PbS

Sweetwater Mine, Ellington, Viburnum Trend District, Reynolds Co., Missouri, USA

Dimensions: 9.5 cm x 8 cm x 6 cm

A perfect yellow calcite crystal rests on a dolostone matrix with minor galena and dolomite rhombs. The specimen came out of the mine sometime prior to 1997.

00G-JUECalcite : CaCO3

Meikle Mine, Goldstrike Mines, Bootstrap District, Elko Co., Nevada, USA

Dimensions: 10 cm x 7 cm x 5.5 cm

A group of lustrous calcite scalenohedrons from Meikle Mine that was collected by Harvey Gordon. A variety of calcite habits were collected from Meikle Mine from the mid to late 90s.


The Casey and Jane Jones article in the Nevada Issue of Rocks & Minerals is a good reference for the locality and also outlines many of the calcite and barite discoveries there:
