Where do you find siderite?

Siderite, a mineral composed of iron carbonate (FeCO₃), is commonly found in sedimentary rocks, particularly in iron-rich deposits. It often occurs in association with other minerals such as calcite and dolomite in limestone environments. Siderite can also be found in hydrothermal veins and as a secondary mineral in iron ore deposits. Locations where siderite has been mined include regions like Germany, the United Kingdom, and the United States.
