  2. Terrigenous sediment - Wikipedia

    en.wikipedia.org/wiki/Terrigenous_sediment

    In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, they are derived from terrestrial (as opposed to marine) environments. [1] Consisting of sand , mud , and silt carried to sea by rivers , their composition is usually related to their source rocks; deposition of these sediments is largely ...

  3. Authigenesis - Wikipedia

    en.wikipedia.org/wiki/Authigenesis

    Authigenesis is the process whereby a mineral or sedimentary rock deposit is generated where it is found or observed. Such deposits are described as authigenic . Authigenic sedimentary minerals form during or after sedimentation by precipitation or recrystallization as opposed to detrital minerals, which are weathered by water or wind and ...

  4. Hemipelagic sediment - Wikipedia

    en.wikipedia.org/wiki/Hemipelagic_sediment

    Terrigenous material includes minerals from the lithosphere like feldspar or quartz. Volcanism on land, wind blown sediments as well as particulates discharged from rivers can contribute to Hemipelagic deposits. [3] These deposits can be used to qualify climatic changes and identify changes in sediment provenances. [4] [5]

  5. Sediment - Wikipedia

    en.wikipedia.org/wiki/Sediment

    The sediment can consist of terrigenous material, which originates on land, but may be deposited in either terrestrial, marine, or lacustrine (lake) environments, or of sediments (often biological) originating in the body of water. Terrigenous material is often supplied by nearby rivers and streams or reworked marine sediment (e.g. sand). In ...

  6. Marine sediment - Wikipedia

    en.wikipedia.org/wiki/Marine_sediment

    Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...

  8. Contour currents - Wikipedia

    en.wikipedia.org/wiki/Contour_currents

    Turbidity currents, on the other hand, flow down slope across regional isobaths and are mainly responsible for supplying terrigenous sediment across continental margins to deep-water environments, such as continental rise, where fine particles are further carried in suspension by contour currents.
