Just a few photos from recent fieldwork at Scremerston, Northumberland, UK.
Headed up to Shaftoe in Northumberland on Tuesday evening trying to make the most out of the decent weather and light evenings as the nights start to draw in.
The rock at Shafoe climbs quite differently to other venues in Northumberland in that its much more rough than the sandstone found at places like Bowden Doors and Kyloe (in and out). Its still a sandstone but with a definite feel of grit about it, similar to the rock at places like The Slipstones down in Yorkshire.The rock on the problems generally has brilliant friction and is of good quality, quite different from the much finer, softer sandstone found at nearby Corby’s…
In terms of the geology of this rougher sandstone is believed to be a fluvial deposit. This means that it is a sedimentary rock produced by a river, and is slightly younger than the Fell Sandstone which makes up Bowden and Kyloe.
One of the most prominent features of the Northumberland scenery is known as the Whin Sill. This is an igneous intrusion, meaning that motlen rock was injected into rock which already existed, mostly following the preexisting weaknesses in the older rock.
In the case of the photo above the headland is made of the harder Whin Sill (dolerite), compared to the sedimentary rocks around it. This contrast in resistance to the elements has resulted in the sediments being eroded much quicker, and the formation of the bay that we observe today!
