Pink layers!

The rock in the image appears to be a type of banded iron formation (BIF) or a similar iron-rich metamorphic rock. These formations are characterized by alternating layers of iron-rich minerals (like hematite or magnetite) and silica (often in the form of chert or jasper). The red and brown hues are indicative of iron oxides, which are common in such formations. Banded iron formations are significant geological indicators of ancient ocean conditions and are often found in Precambrian shield regions. They are not only of scientific interest but also have been historically mined for iron ore.
