Maltby beck deposits

This is were i first noticed the deposits.


After scraping away the stuff shrouding the deposits, i could make out that i had the same sequence of deposits as at Stainton beck about a km to the east.

There seems to be at least 7 different layers in this excavation and as at Stainton the gravel bed is rich in fossils.
The gravel bed can be seen above the spade handle with the red-brown deposit above as at Stainton.

This red-orange deposit was a surprise Ive not come across it before, at least not in this state.This pic shows the sequence of deposits including a thin layer of blue clay below the red orange deposit.

Blue clay found above the Stainton gravel beds.



The image above shows the deposits are level and uniformed.

Close up of blue clay deposit about 1000mmm thick.

Laminated sandy clay deposits interrupting the gravel bed, below?

The image above shows the blue deposit above the gravels.

 To the right half of the image above ive cleared the brown red clay from above the blue deposit.
(25,01,12)  I now know the blue- grey deposit is thicker than first thought, ive recently found it to be over a metre thick 3 metres up stream.

Blue deposits

I have now cleared more of the material shrouding the blue deposits at Stainton


Some of the red you can see is caused by the dust from the deposits above but there are a lot more of the red veins than first thought.
The clay both red and blue is extremely tough almost rock like, and appears greasy.




There is quite a lot of small pieces what i think is Mercia mud stone in the red clay




The blue clay has very little covering it in this part of the dig.


The image below i think shows two separate red brown layers, something we did not notice with the  cores taken with the auger.


I have dug a 1.5 metre test hole about 15 metres down stream, with no sign of the blue deposit, so it seems this is a high point in the blue deposit at least as far as the beck side is concerned.


This image shows the site the last auger work was carried out just to the bottom left of the pic, we reached 3 metres without encountering the blue deposit or the rock head.

More magnetic rock found in the Stainton gravel beds.

Unknown rock dug from the Stainton gravel beds, the magnets used are not rare earth magnets.


The pink magnet can be seen stuck to the rock    The Stainton gravel beds
