A name made up by someone who doesn't understand chemical nomenclature nearly as well as they think they do. Most likely they were trying to come up with a fancy word for "water".
"Hydrogenous" is just silly; beyond the problem of making the root of hydrogen "hydrogen-" rather than the more proper hydr- (cf "hydride"), it implies that hydrogen has at least two common positive oxidation states, of which +1 is the lower. This is, of course, nonsense, since hydrogen has one proton and +1 is therefore the highest (and only) possible positive oxidation state.
It's just barely possible that they thought the existence of hydrogen peroxide (empirical formula: HO) implied that hydrogen might have a +2 oxidation state. This is still wrong, though, it's just wrong in a different way.
Manganese nodules are an example of hydrogenous sediment, which forms directly from ocean water through chemical precipitation. They are typically found on the deep ocean floor.
No, manganese nodules are examples of hydrogenous sediment. They form through chemical precipitation in seawater, often around a nucleus like a shark tooth or a shell, rather than being produced by living organisms like biogenous sediment.
Copper (I) Oxide or Cuprous Oxide
CuO = Cupric Oxide Cupric = Cu2+ and is not Cu The correct answer would be CuO = Copper Monoxide Copper (II) oxide is the name of the compound CuO.
Al2O3 is the chemical formula of aluminium oxide.
Calcium oxide.
Hydrogenous sediments are formed when minerals precipitate from the ocean, or they can be formed when minerals in the water react with older sediments.
Calcareous ooze
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
It's material found in bottom sediment or in the water column of a body of water that was precipitated out of stuff in the water, ie. hydrogenous material does not come from a terrestrial, cosmic or biological source.
