Siderite cleavage
WebSiderite has been found in pegmatites in crystals up to 25cm on edge. Most crystals are, however, in the 2-3mm range. It is a very common mineral at Mont Saint-Hilaire. ... Cleavage {101} is perfect. Fracture is conchoidal to uneven. Hardness is 4 Specific Gravity is approximately 3.95 g/cm WebSiderite belongs to the calcite group and forms series with rhodochrosite and magnesite. Diagnostics. This stone is too soft to be cut and is hence rarely faceted as a gemstone. As it is a carbonate, it would give effervescence (bubbling) when in contact with acids; strong eye visible doubling due to the high birefringence.

WebSiderite is roughly the equivalent of calcite but with iron replacing the calcium. The iron has little effect on most structural properties such as cleavage and crystal form; but does effect properties such as density, color, hardness and electro-chemical properties. bofrost veganWeb05.AB.05 Siderite FeCO3 R 3 c 3 2/m : 05.AB.05 Smithsonite ZnCO3 R 3 c 3 2/m : Other Calcite Information: References: NAME( Duda&Rejl90) PHYS.
