Authigenic sediment, deep-sea sediment that has been formed in place on the seafloor. The most significant authigenic sediments in modern ocean basins are metal-rich sediments and manganese nodules.
The most common minerals that occur in nodules are siderite, gypsum, calcite, quartz, and barite/celestite. Siderite nodules, concretions, and liesegang (iron-stained) banding are a very common type of mineralization found in eastern and western Kentucky sandstones.
