The rock to the left has the same indentations as the split rock to the right they both attract a small magnet strongly, i believe they must a be basaltic rock but ive never come across this surface pattern before. Also one was dug from the gavel beds at Stainton the other found in Ormesby beck, but ime certain it originated from the same gravel bed in that location.
I first thought as can be viewed in earlier posts, that most of the stone in the possible structure was mostly yellow sandstone. But it seems that the stone is of all kinds, but i have noticed after washing and drying the stones i have had to remove to get further in to the bank, the stones are of very different colours including blue ,violet , red , and yellow, and all have one thing in common they all display well preserved fossils.
This is what i believe is part of the same structure, on the opposite side of the beck, what i think has happened is the tree roots from the large tree above over a long time of slow growth have caused the sandstone structure? to splay to the left and right, as well as pushing some of the sandstone down into the gravel bed it sat on.
The image above shows one of at least two large sandstone pieces that have been undisturbed by the roots and sit on the gravel bed in the same way as the structure? on the opposite bank, a believe it will go a lot deeper into the clay deposits, its going to be very hard to expose further as the roots of the dead tree above are huge.
This recently found deposit was initially blue, but over the last week has turned green, this may be due to a chemical reaction to being exposed ?
The stone to the rear attracts the small magnet, i think this stone unlike the yellow sandstone viewed to the front is whinstone, the next two stones appear to be grey limestone, then the yellow stones.
The highest stone in this image appears to have been rounded ie no sharp edges.
My worry is that if the bank collapses it will destroy what could be a very important discovery.
Ormesby beck about 3 miles east of Stainton beck, has the same sequence of deposits in this image the ever present red clay sits beneath the gravel bed.
As at Stainton, Maltby, and Stainsby becks the gravel beds contain organic material.
This thin line of bright red then blue running through the red clay looks to be the same as found at Maltby, it can be seen clearly running beneath the beck.
This is further upstream showing the blue grey seem that has been uncovered above the gravel bed at Stainton and Maltby.
A close up of the first excavation showing the gravel bed sat on the red clay, the gravel bed contains magnetic whin stone as at all the other locations.
This is an image of my first contact with the possible structure
I did at first think it was a sandstone boulder crushed and split by geological pressures from above, but then found limestone included in the line of stone going into the clay bank.
It does appear to have maybe collapsed to this angle.
I have informed certain professional organisations of this excavation, and hope to get some feed back soon, i am worried about any damage that could be done due to flooding.
This could well be some geological phenomena i have not seen before, but it looks very much like it was built.
