What is chert?</h3>
- Banded iron formations are made up of alternating light and dark chert bands.
- Chert is a sedimentary rock that forms in a variety of ways and is almost entirely composed of silica (SiO 2).
- When the siliceous skeletons of marine plankton are dissolved during diagenesis, silica precipitates from the resulting solution, biochemical chert is formed.
- Chert layers, which occur as irregular beds or rounded nodules within limestone formations, are common in eastern Kansas.
- Because it is harder than limestone, chert is more resistant to erosion.
- The Flint Hills' chert-topped hills are the result of the landscape's uneven erosion.
Therefore, banded iron formations are composed of alternating light and dark bands of chert.
