Example of the magnetic properties of the Cleveland dyke at Stainton.

I dug this cobble from Stainton Quarry and as with the majority of the whinstone ive tested in this area, it attracts a magnet. 

As far as i can gather at this preseant time the Andesite dyke stone from this area has never been reported as magnetic ie attract a magnet

 

The fact that this cobble attracts the magnet, and others I've tested in the old Stainton quarry workings, makes it clear that for some reason the dyke stone in the Stainton area has a different make up than that of other stretches of the dyke, one being the outcrop about a mile north west at Stainsby beck, the dyke stone in the outcrop did not hold the same magnet, yet a layer of broken down whinstone laying between two separate clay deposits above the dyke outcrop was all magnetic?

Mandible excavated from Stainton gravel beds.

My Daughter found this jaw fragment from a new dig in a section of packed gravel 5 metres east of my main dig at Stainton, at the moment i can not identify it. The teeth don't match bovine horse or cervidae that i have or have viewed. The radius i believe could be from the same animal? it apeares to be cervidae?

Flint ( burrow ) Nodule

I found this recently how and why it was among the magnetic whinstone i am studying at the moment i have no idea.
And i state now it was not excavated from the Stainton gravel beds !
 

The nodule has a rough outer texture but has razor sharp edges!

I am told these burrow nodules usually contain fossils but flint is new to me , and at the moment i don't quite know what to look for !?

I think its a beautiful piece almost alien in appearance.
