Ironrich sedimentary rocks IPFS

Some examples of minerals in ironrich rocks containing oxides are limonite, hematite, and magnetite. An example of a mineral in ironrich rock containing carbonates is siderite and an example of minerals in an ironrich rock containing silie is chamosite. [2] They are often interbedded with limestones, shales, and finegrained sandstones.
