Hydrogenous sediments are formed from the precipitation of minerals from seawater. The main types include manganese nodules, which are rich in manganese and other metals, and phosphorites, containing high levels of phosphate. Other examples include carbonates, such as limestone and dolomite, and sulfides, which are often associated with hydrothermal vent activity. These sediments typically form in specific marine environments where conditions favor mineral precipitation.
Calcareous ooze
minerals that crystalize directly from ocean waters
The type of sediment that forms from minerals crystallizing directly from seawater is called hydrogenous sediment. This sediment is created through chemical reactions in the ocean, leading to the precipitation of minerals such as manganese nodules and phosphorites. In contrast, biogenous sediments originate from the remains of marine organisms, terrigenous sediments come from land sources, and siliceous ooze is a specific type of biogenous sediment composed primarily of silica from diatoms and radiolarians.
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.
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 sediments are formed when minerals precipitate from the ocean, or they can be formed when minerals in the water react with older sediments.

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.
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.
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.

The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.

Chemical sedimentary rocks, such as limestone and chert, can form when minerals crystallize from seawater. These rocks are typically composed of minerals that precipitate out of solution in bodies of water, including oceans.
