The geological layers found at this location are as follows -
Red - brown loamy friable clay, with very little stone or pebble content.
Blood red hard packed stoneless very dry clay, average thickness 300-400 mm
Mercia mudstone containing Tufa with fossils.
Ive recently been informed by Andy Cooper a good friend and in my mind an expert in the geology of the Cleveland area, that the red stone-clay could be the result of a fault in the Mercia deposits.
I have informed Andy that ive found that the Mercia mudstone outcrop in the Stainsby beck area of Thornaby on tees, is a lot larger than first reported, ive identified at least a 200 metre stretch of the western bankside, has visible mudstone outcrops.
