European oolitic iron deposits, commonly called Minette-type deposits, contain ooliths of siderite, a siliceous iron mineral known as chamosite, and goethite. The deposits were formed in shallow, near-shore marine environments and are most extensively developed in England, the Lorraine area of France, Belgium, and Luxembourg.
