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.
