It lies at the confluence of four dry valleys formed by the meltwater at the end of the last ice age which deposited onto the bed rock of chalk, alluvial gravels, silts, on which the town now sits.

Silts, which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays, but there is some overlap in both particle size and other physical properties, and there are many naturally occurring deposits which include silts and also clay.

Geologists and soil scientists usually consider the separation to occur at a particle size of 2 µm ( clays being finer than silts ), sedimentologists often use 4-5 μm, and colloid chemists use 1 μm.

Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils ' Atterberg Limits.

ISO 14688 grades clay particles as being smaller than 2 μm and silts larger.

For similar reasons, they are also common in tidal creeks, where tides bring in large amounts of coastal silts and muds.

In Flanders, sands, gravels and marls predominate, in places covered by silts.

The ruins of the Lycian and Roman town are mostly covered by alluvial silts.

During the Eocene (~ 55. 8 — 33. 9 Ma ) and Oligocene (~ 33. 9 — 23 Ma ), the Appalachian Mountains began to uplift and the erosion rate increased enough to fill the Gulf Trough with quartz sands, silts, and clays via rivers and streams.

The Ogallala Formation is composed of fine to course sand, some gravel, calcareous silt, silty sands, silts and clays.
