It was affected by the Pan-African orogeny, although the later Hercynian orogeny produced fewer changes and left the Maseta Domain, a large area of remnant Paleozoic massifs. During the Paleozoic ...

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).Its name comes from the Ancient Greek word σίδηρος (sídēros), meaning "iron".A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus.
It is commonly found as radiating clusters of acicular needle-like crystals in cavities in sulfide rich limestone and dolomite or in geodes. It is also found in nickel-iron meteorites, such as CK carbonaceous chondrites. [8] Millerite was discovered by Wilhelm Haidinger in 1845 in the coal mines of Wales.
