Staintons unknown geology

The excavation above measures about 1.5 by 2 metres.



This image shows two separate unknown clay deposits, I have recently visited the site with Andy cooper a local geologist who has informed me he believes the deposit is probably alluvial i am waiting for his full report on the sites, and will post any new information as i get it.
There is also a separate seems of red clay running through the blue deposit..

.  There is an identical deposit a kilometre away at Maltby beck, about the same depth in relation to the surrounding land as the exposed layers at Stainton beck.




The blue layer is at least 3 metres deep and sits on top of an older deposit, . The beck is currently cutting through the older red deposit,  and looks to have been doing so for a very long time

Ancient sediments and Stainton gravel beds.





The lower red clay is at least 2 metres thick with no large rock present only sporadic blue clay with Carboniferous trace fossils




Note this is not boulder clay !



The layer of red clay below the gravels is very tightly packed and has the odd large rounded and un rounded  rock lodged at its meeting with the gravel layer containing Jurassic fossils mostly Gryphaea.

The image above shows how what i think is alluvium had shrouded these older layers.



 Outcrops of blue clay containing Carboniferous plant fossils found in the red lower clay.

View showing the rough depth to the surrounding land, but it does rise rapidly after the depth shown!



This pic shows how this bit of bank has actually already lost a lot of the soil and alluvium? that used to shroud the layers ime now exposing.
