Rocks from the middle Precambrian, 1200 - 2500 Myr hold most of the Earth's iron ore, mainly as hematite (Fe 2 O 3). This can be taken as evidence that the oxygen content of the atmosphere was increasing during that period, and that it was abundant enough to react with the iron dissolved in shallow lakes and seas.

As a general rule, the specific gravity will vary with iron content, from a low of 2.8 to as high as 3.8. The absorption of the material is typically very low. Yusof (2005) reported granulated copper slag has specific gravity of 3.4 to 3.6; bulk density of 1.76 to 1.92, and water absorption (% by mass) of 0.13.

The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.

Skarnoid is a descriptive term for calc-silicate rocks which are relatively fine-grained, iron-poor, and which reflect, at least in part, the compositional control of the protolith (Korzkinskii, 1948; Zharikov, 1970). Genetically, skarnoid is intermediate between a purely metamorphic hornfels and a purely metasomatic, coarse-grained skarn.
