Banded iron formation, or also referred to as BIF, is unique sedimentary rock of biochemical origin. Unique because of their unique make up, unique age and unique origins. These rocks are very old.
BIF date to as old as 3 billion years old, but most are aged at around 2.5 billion and some are as "young" as 1.8 billion. So, the Earth's oldest banded iron formation is 3 billion years old.
