The Ulsan carbonates (Fig. 1) have long been interpreted as limestone of Paleozoic age or "age unknown" and as the host of a skarn-type iron (magnetite) deposit due to the intrusion of Cretaceous granitic rocks (Park Park 1980 Choi et al. 1999). However, a Paleozoic marine limestone hypothesis fails to explain the spatial association or the relationship between carbonate and ultramafic rocks in a concentric, ellipsoidal shape surrounded by Cretaceous sedimentary, volcanic, and granitic rocks. The sedimentary hypothesis also fails to explain the isolated exposure of a funnel-shaped Paleozoic marine limestone where no marine limestone has been previously observed within the Mesozoic Kyongsang Basin. 

This mineral is an important ore of iron, 72 -r heing metallic iron. Magnetite sometimes is referred to as magnetic iron ore. 

There are only a few minerals that are attracted to a magnet, and only one that sometimes is itself a natural magnet. Those species that are attracted by a magnet include magnetite, pyrrhotite, and native iron. Magnetite occasionally occurs as naturally magnetic specimens, which have the common name lodestone. ...

While for the early demonstration units, osmium and uranium had been used, it was the promoted iron (magnetite) catalyst developed by Mittasch that opened the door to commercialization of the Haber-Bosch process. Osmium had to be ruled out for cost and availability reasons, uranium is impracticable due to its sensitivity for permanent oxygen compound poisoning. Emphasizing the outstanding work of Haber, Bosch, and Mittasch, magnetite-based catalysts are still state of the art today.
