You might mean "androgynous." An androgynous lesbian is a woman who has romantic and/or sexual feelings for other women, and looks androgynous- they are neither overtly feminine or masculine, but somewhere in-between, occasionally making it difficult to tell their gender.
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.
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.

Calcium oxide.
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.
