Quaternary alluvium.

Palaeoenvironmental investigations have been made of late Quaternary sediments infilling the lower Tyne valley at Scotswood, Newcastle-upon-Tyne. 18 km upstream from the mouth of the river. Attention has focused on the Holocene alluvial sedimentary sequence using sedimentological, geochem- ical and palynological analyses.

A …When excavating a field of Quaternary alluvium (modern sediments), a layer of limestone bedrock is encountered. The limestone is found to have been intruded by an igneous dike. Both the limestone and the dike are fractured by a fault. Place these features in order from oldest to youngest: Igneous dike, limestone bedrock, quaternary alluvium, fault.Most alluvium is Quaternary in age and is often referred to as "cover" because these sediments obscure the underlying bedrock.

Alluvium is a loose soil, or sediment, not fused into a rock, formed by erosion, reshaped by water in some form, and redeposited in a riverside setting or by a river.
