Siderite: The mineral Siderite information and pictures
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. Excellent gemmy greenish crystals come from Isere, (especially at Allevard), France.

Siderite - an overview | ScienceDirect Topics
The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996 ), distinctively different from that of pyrrhotite ( Section 5.08.3.9 ). Siderite is paramagnetic at ordinary temperatures and carries no NRM.
