iron ore was formed by chemical sedimentary processes

These deposits areformedby ground water, and occur mainly in sedimentary rockslike-limestones,sandstones and shales, in the presence of some reducing agents. The occurrence of some manganese deposits in the Keonjhar District ofOdishaare believed to have formed by this process where bymanganeseat one level has been remobilised to the other and its subsequent concentration at that level.

Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.

Although no one witnessed the deposition of the Navajo Sandstone, it possesses features that point to this interpretation. For example, the tracks of land-dwelling animals rule out a marine origin, and other features such as current ripple marks and large-scale cross-bedding as well as sorting of the sand grains are much like the same features seen in desert dune deposits today.
