I've certainly not heard of exactly that form in Ireland. Sounds most odd.

A couple of things though. The Hound of Hostages was a cairn covered with a clay layer. Newgrange was built in several phases. Phase one was a low mound. The next couple of phases raised the mound around the passage. There was enough of a pause between phases to allow grass to cover the mound.

As to your actual question, I've never heard of any collection of that information.

Rune, You know Willhelm well.
You know, I hold you in the highest esteem.
A layer of organic, a layer of non organic, etc.
Build up, accumulate, life.
Goddess in touch, so near to devine.
I am a very ordinary person, with no belief structure,
no preconcieved ideas, got the answer, before hearing the question.
Life , must be so simple, when you just work towards the answer.
Just destined to be an odd-ball.

Just been reading Burl's Rites of the Gods, and he points out, that in some sites soil and debris from their living site is also found under mounds. It's a sort of a fertility rite, bringing everything back for renewal. I expect the layering of mounds may point to a more methodical approach of building a cairn but the idea that the earth needs to be magically renewed to grow crops would be bound up with the burial of the dead. He's quite strong on child sacrifice as well during early/ middle bronze age, seemingly as a foundation offering when some barrows/henges were built.

Something else you may like to consider is the use of the red soil as mentioned in Chris's post.
The use of red materials in prehistoric graves is well known and extends back into the paleaolithic.
I know of two North Yorks burials were red was deliberately placed in a funery monument.
One was a burial discovered in a rock fissure (? windypit), just north of Pickering where the body was embeded in a layer of stiff red clay. The second was a grave beneath a barrow at Scamridge where the skeleton was laid upon a bed of deliberately chosen red gravel.
Many believe that the blood red colour may be a symbol of life itself.

Hi Rune, here are the links for the Towthorpe Plantation barrows info at English Heritage, hope they are useful to you. I've just had a quick flick through a few of them and it looks like they may all have been constructed using some quantity of Duggleby clay although there is a suggestion that the reddening of the clay could have occurred as an interaction with ash within the barrow.

If you haven't already got them then I'd recommend the Godfrey Edition old OS maps 1905 for the North and South Wolds (sheets 64 and 72), they're only a couple of quid each and show the area from the north of Driffield to the south of Beverley and it looks like 100 years ago the area was still peppered with barrows.
I'll have a dig round and see if I've got any more recent pictures of the sites around that area.

Cheers-
Chris
