Astley sunken lane

Geological Overview
This sunken lane leads from Astley church down to Dick Brook and Newbridge Coppice. The track cuts down through several layers (beds) of red sandstone – a Triassic-aged rock which formed around 230 million years ago.

Many of the different layers of sandstone display varying sedimentary structures. Beds differ in thickness, some displaying no features, others are finely laminated, other are cross bedded.

With the diversity of sedimentary structures and grain sizes, some of them subtle, this sunken lane is a pleasing location to explore the environment in which the sediments were first deposited to later be formed into rock.  What type of environment allows for this rapidly (in geological terms) changes in environment to create the sedimentary structures seen?
