Maltby clay Deposits

Ive now cleared the gravel bed, and have noticed it is interrupted by a stoneless deposit, it can be seen to the right of the spade handle.

There is the same intrusion by the same type of deposit in the gravel bed a km east at Stainton beck.

This image does not exaggerate the colours if anything it does not do them justice.

This is a close up of the deposit that intrudes the gravel bed, there is another separate blue layer above then the dry hard packed friable red brown loamy clay that lays above everything in this area.

Close up of the gravel bed with the dark red clay below, i now am sure this gravel bed is part of what i have now named the Stainton gravel beds.

The intruding deposit can be seen to the right of the spade handle.

The lower thin clay layers look like there painted with gloss, the image really doesn't do them justice.

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.

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 true superficial Geology of south west Cleveland north east England.And a map of the locations of my excavations, and locations of the Stainton gravel beds

This excavation shows about 400mm of top soil then the ever present friable red-brown loamy clay with minor pebbles.

As far as i know this red brown deposit covers this whole area sometimes very thick, what i am begining to understand is this deposit is so close to the surface in places it makes the ground around here glow red as the sun lowers and the ground is wet.

The diagram above shows what i now know to be the true superficial geology both to the north and south of the Cleveland dyke in the south west area of Cleveland north east England

Agar 1954 on the deposits in the south west area of Cleveland.

Agar covered in detail the deposits to the north of Stainton created by the ice-dammed water-body that is said to have stood far below the 50 metre elevation of the Stainton site's.  Neither of the papers i have now looked at explicitly cover the south west area of Cleveland, but Agar ( 1954) maps the area as being till- covered with no detail on other beds in the area.

I can now with some confidence state that Agar mapped the area wrong, the area is far from a till covered glacial mess in fact i am yet to come across anything that resembles a till deposit or indeed any glacial erratics on the surface, every area i have excavated is proof in itself that Agar mapped the area wrong, and in doing so tells me he never actually looked hard enough to have the right to map it at all .
