Because of its resistance to weathering it is very common in stream sediments and in residual soils.

Instead a V-shape ends at a slot canyon halfway down with a relatively small and steep alluvial fan on which the stream sediments collect.

In the 1990s, Cyprus Minerals conducted stream sediment, soil and rock sampling on Sona.

Later investigators found that the bones and artifacts were mixed by redeposited stream sediments, confusing the early interpretations.

Regional geochemical exploration has traditionally involved use of stream sediments to target potentially mineralised catchments.

The foreset bed is formed when a stream carrying sediment meets still water.

These indicator minerals are generally sought in stream sediments in modern alluvial material.

Breakdown piles, stream sediments, and mud deposits are also important to karst researchers.

The stream sediment may not, therefore, reflect local bedrock composition but that of exotic glacial deposits, and care is needed in site selection and data interpretation.
