detrital

detrital

Detrital sediment accumulates at the bottom of the river.

Definition

Adjective (Geology): Relating to or consisting of detritus — that is, loose fragments or particles of rock, mineral, or organic material that have been worn away from a larger mass by natural processes such as erosion, weathering, or biological activity.

Usage Examples
  • (The rock was made up of small fragments from pre-existing rocks.)
  • (These minerals are fragments that have been transported and deposited.)
  • (These tiny fragments help trace the origin of sedimentary materials.)
Advanced Usage
  • "detrital sediment": sediment composed of particles derived from the weathering of pre-existing rocks.
    • River deltas often accumulate thick layers of detrital sediment. (The sediment is made of eroded rock fragments.)
  • "detrital input": the amount of fragmented material introduced into a depositional environment.
    • High detrital input can dilute the organic content in marine sediments. (Large volumes of rock fragments reduce the proportion of organic matter.)
Variants and Related Words
  • Detritus (noun): the loose material that results from the wearing away of rocks; also, organic waste or debris.
    • The forest floor was covered with leaf detritus. (Decomposed plant material.)
  • Detritivore (noun): an organism that feeds on detritus, such as earthworms or woodlice.
    • Detritivores play a key role in breaking down dead organic matter. (They consume and recycle detritus.)
Synonyms
  • Clastic: (of rock) composed of broken fragments of older rock.
    • Clastic sedimentary rocks are formed from detrital particles. (Synonymous in geological context.)
  • Fragmental: consisting of fragments; broken into pieces.
    • The fragmental nature of the deposit suggests a detrital origin. (Indicates broken, transported material.)
