TRM32XXX: Fluorite with Siderite

Fluorite crystals on a Siderite matrix that has acquired an intense reddish colour as a result of oxidation. The matrix displays cavities and dissolution features that appear to correspond to former crystals, probably of a carbonate, now completely dissolved, whose arrangement suggests an epitactic growth relationship with the Siderite. The contrast between the lilac Fluorite, with its paler zones, and the altered Siderite gives the specimen a very distinctive appearance. Geologically, Greenlaws Mine forms part of the hydrothermal vein system of the North Pennines Orefield, hosted by Carboniferous carbonate and clastic rocks. The association of Fluorite and Siderite reflects a fluorine- and carbonate-rich hydrothermal stage, followed by oxidation processes that partly modified the matrix and produced its present reddish colours.
