In some fine-grained sediment, the worm also forms a burrow up to the surface from its feeding cavern, actively keeping it open.

Such flats consist of fine-grained sediments infused with alkali salts.

These winds picked up and transported large quantities of loose, fine-grained sediment brought down by the glaciers.

The very dark area on the northeast side of the crater is probably covered by smooth material such as fine-grained sediment.

The footprints, which form tracks, occur in several levels on bedding planes of fine-grained sediments.

A very thick (2000 to 3000 m) succession of fine-grained detrital or calcareous sediments was deposited.

These two types of fine-grained sediment are typical of deeper-water settings.

This occurrence is due to major influx of fine-grained sediment that accumulates at the north end.

Water entering the cave collects along the lowest part of the floor, then slowly infiltrates into the fine-grained, mud-cracked sediment or evaporates.

Deposits of fine-grained wind-blown glacial sediment are called loess.
