The story of the word

Wilhelm Haidinger fixed the name on iron carbonate in 1845, after it had been thrown at lodestone and several other iron minerals in turn. Meteoriticists use the same word for iron meteorites, a separate tradition and a durable source of confusion. Sidereal is no relation whatever: that comes from Latin sidus, a star.

The seam was mostly siderite, poor stuff by modern standards but enough for a local furnace.
