Whinstone in Ormesby beck

I have discovered today that like Stainton, Maltby, and Marton west beck, Ormesby beck has an abundance of whinstone both in the beck and in the same buried packed gravel layer as found at all the other becks.

The image above shows one of the many pieces of whinstone in the packed gravel layer, and as with Stainton all pieces checked attracted a magnet.

The image above shows a piece of whinston split this piece was deep in the undisturbed gravels.

These images show the gravel layer with the red clay layer below again the same as found at Stainton, Maltby, Marton west beck, and Stainsby beck.

Naturally exposed red clay layer Ormesby beck in this area seems more advanced in the processes of cutting through the red clay layer than the other becks.

Rounded Whinstone in the banks.

This is the first time ive seen this coloured seem in the red clay.

Note how deep the beck has cut into the red clay.

More Whinstone i would say Whinstone is by far the most abundant rock in this stretch of Ormesby beck, and all tested attracted a magnet.

These pics show a natural exposure of the gravel layer with the red clay below, and at least two other deposits above the gravels very much like my main dig at Stainton.

Organic material in the blue gray seem just above the gravel layer.

 This is the biggest whinstone boulder ive come across at any location so far, it also attracted a magnet.

The hammer sits on the red clay layer then the gravel layer then the blue gray layer that contains the organic material then the sandy deposits.

The gravel layer is very like that at Stainton in having finer orange gravels to the bottom containing organic material

I am starting to believe all the similar exposed layers in the deepest parts of all five becks are connected ie the same event caused the sequence of deposits in all the becks.

The only possible way i can think of that deposited this whinstone here and in the other deep beck valley locations is ice, yet i can not explain the uniformed layers theres nothing erratic about these deposits in any of the locations, with the added complication of the organic material in the lower packed fine gravels at Stainton and Ormesby becks uncovered so far !  

Magnetic whinstone of Marton west beck ( Stainton gravel beds )

This Andesite (whinstone) boulder in Marton west beck south Middlesbrough is magnetic.

Every whinstone boulder i checked attracted a magnet, this stretch of Marton west beck has a very large amount of whinstone of all sizes, all seem to be water worn, and all the Andesite (whinstone) i tested was magnetic.

I presume these magnetic Andesite boulders were originally part of the dyke in the Stainton area and were broken away by the last ice advance.

Ime not sure what rock this is yet, but it came from the same gravel layer as the magnetic Andesite (whinstone)

This stretch of Marton west beck has by far the largest deposits of Andesite dyke stone i have found anywhere in the south Cleveland area, the gravel layers in the beck banks are full of it, and all tested were magnetic.

These images show what i believe is the same red clay ive found underlying everything in the south west Middlesbrough area, with the gravel layer above.

These images show magnetic Andesite still in the gravel layer.

The image below hopefully shows the amount of material above these layers, i would say at least a 35 metres

These images show the blue clay seem that ive also found in the red clay layer at Stainton, Maltby, and, Ormesby becks.

Red clay layer with gravel layer above, again the same as seen at Stainton, Maltby, and ormesby becks.

Magnetic whinstone boulder from Stainton gravel beds.

These images show my daughter pointing out the small magnet stuck to this worn whinstone boulder.

The boulder is buried into the bank of Stainton beck.

The boulder is extremely tough i could not crack a piece off, but exposed enough fresh surface to be able to see it is Whinstone.

I placed the magnet over a thin piece of paper to make sure nothing was helping the magnet stick.

Magnetic Whinstone of Stainton beck Middlesbrough.

This shows that even the boulder sized Whinstone from these released ancient river gravels are  magnetic, i can not find any reference that states or shows images of the magnetic attraction of kind ive shown here.

The biggest piece of magnetic Whinstone is about 4ft by 3ft most of the rocks in the pic are magnetic, the magnet used is very small so Ive placed a thin piece of paper to hopefully highlight it, and to create a smooth surface to make sure nothing was helping the magnet to stick.

I dug a leg bone out from under this magnetic Whinstone.

Packed gravels and red clay at Ormesby beck.

These images show yet again the red clay underlying the packed gravel layer, as at all the other beck locations excavated in the south west area of Cleveland.

I was unable to expose a lot as i had no equipment, but the bit i excavated leaves me in no doubt it is the same geology that i have already exposed at Stainton, Marton, Maltby, and soon i am confident i will uncover the same deposits at Stainsby beck.

The red clay can be seen bottom then the packed gravels, with the normal shroud of what i believe to be Alluvium.

I strongly believe most of the natural stone in these becks, where once part of these packed gravel layers, and have been released by the beck water cutting through the becks in all locations in the south west Cleveland area, and is now cutting through the same red clay deposits.

Angle of blue clay deposits at Stainton

Here you can see the already excavated area to the left and the un excavated section to the right discoloured by the brown / red fryable deposit above

The only  un natural angle here was created by my spade to the centre and left of the pic the facing angle is as it was excavated.

This angle would in my opinion be a constant along this stretch of beck if the alluvium? was removed.

This shows the structure of this deposit, there must have been a large time difference between these two deposits surley?

The clay angled layer is blue although discoloured in the pics by shine and dust from the above layer.

The angle cut by my spade then the natural angle which meets the ever constant red clay layer in this area of south west Cleveland.

The blue clay contains fossils ie gryphaea and ammonites, also a lot of calcareous lime stone nodules. Myself and two Geologists have recently ( October 2011) used an auger to a depth of 1.75 metres down from a shelf above the grey blue clay deposit and have indeed discovered it continues to rise at this angle. The brown red deposit above  has no large stones samples of sand stones and Mercia mud stone were abundant but in very small sizes.    ( Please see more recent post on this excavation,  Extention of excavation into blue clay)

Maltby beck excavation

This excavation shows the same sequence of deposits that have been exposed at Stainton beck, at roughly the same depth in relation to the surrounding land.

The image above shows how little soil cover there is above the aluvial deposit, less than 100 mm in places

The glove marks where the  deposit stops and the gravels start, then as in all my excavations the dense red clay below.
