Siderite, Calcite

This is an old-time miniature specimen plate from the historic iron mines of West Cumberland, England. It features super-sparkly, brassy siderite micro-rhombs and clusters, along with discrete botryoidal calcite, all set on a dolomite matrix. This area is particularly noted for its deposits of siderite, sphalerite, and various lead-zinc minerals, making this specimen a quintessential representation of the locality’s rich mineral diversity and classic English mineralogy.
