Use of red ochre by early Neandertals PNAS

The use of manganese and iron oxides by late Neandertals is well documented in Europe, especially for the period 60–40 kya. Such finds often have been interpreted as pigments even though their exact function is largely unknown. Here we report significantly older iron oxide finds that constitute the earliest documented use of red ochre by Neandertals.

Here occurs the mineral Red Ochre, a clay containing a very high proportion of Ferric oxide (Haematite) generally 30% to 40%, giving it a deep red hue, but some even up to 70% or 80%2 with a darker almost purple colour. The lowest percentages gave a bright yellow hue to the clay. Somerset Redding

The iron ore, limonite, is another example. The ore is a mixture of hydrated iron(III) oxide-hydroxides. Iron(II,III) oxide, which has the formula Fe 3 O 4, is a combination of two- and three-valent iron. It occurs as magnetite, a valuable iron ore and the most magnetic naturally-occurring mineral on Earth.
