Calcium oxide.
Manganese nodules are polymetallic concretions found on the ocean floor and are formed through a slow process of precipitation and accumulation of manganese and other metals. They are a type of sediment known as hydrogenous sediment, as they form directly from seawater and not from the breakdown of rocks or organic materials.
Hydrogenous sediments are formed when minerals precipitate from the ocean, or they can be formed when minerals in the water react with older sediments.

not a hydrogenous sediment?
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
Hydrogenous sediments form when minerals precipitate directly from seawater as a result of chemical reactions or biological processes. For example, manganese nodules and phosphorite deposits are examples of hydrogenous sediments that form in this way in the deep sea. These sediments accumulate slowly over time on the ocean floor.

Hydrogenous material refers to substances containing a significant amount of hydrogen. These materials are often found in natural environments like Earth's crust, water bodies, and living organisms. Examples include water (H2O), hydrocarbons, and organic compounds.
