Siderite and calcite can form similar crystal habits, although siderite is far less diverse. The typical habit for siderite is the rhombohedron. Most of the time crystals are found in the standard rhomb shape but noticeably flattened rhombs and rhombs with curved surfaces are also well known.
Siderite is a common mineral and is found worldwide in many different environments. Only the most noteworthy will be mentioned here. Classic Siderite occurrences in Europe include Neudorf in the Harz Mountains, Germany; and Panasqueira, Portugal.

In the United States, they have been found mostly in hilly regions and toward the bottom of the slopes. Another common condition is a tight trough, or basin, formed by the iron formation and an intruding dike. Important orebodies have been found that were completely without, or almost without, outcrop, in some cases being covered by slate.

Nonetheless, this is a great hard to find reference specimen from this classic Colorado locality. The Climax Mine was the largest producer of Molybdenum ore in the United States, and talks of the mine reopening have been going for years, and we would hope to see more of these noteworthy minerals from Climax to make their way back on the market.
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
MagnesiteSiderite Series, RhodochrositeSiderite Series, SideriteSmithsonite Series. Crystals typically found as brown to tan rhombohedrons in clusters, faces often curved or composites; more often found as medium to dark brown massive finegrained material or as massive crystalline material with exposed curved cleavage surfaces.
The 360 acre mine and the complex is now preserved by the Roxbury Land Trust and is on the National Register of Historic places.
