Great story S. The main difference is the greater number of phases , as derived from the more recent work .
Yes to be truthful I don't know how all this phase stuff works or how to interpret it. I know because of my background in the building trade and groundwork I have done, that you can only go so far before you have to compact everything so that what you have so far is stable. Once done off you go again. Now whether that is what is regarded as a 'phase' I don't know but maybe Fachtna could put us straight here!
When you compact a base for a building you 'blind' it with sand or grit or at least something that fills the gaps left by larger materials and it forms a layer. Anything over that is considered another layer but still part of the same structure so not a separate build but yes another phase.
Something else we don't seem to hear about anymore is the 'wedding cake' or drum formation that Prof Atkinson mentioned and the series of radial walls which divided each drum into compartments that were then filled with compacted chalk. Those walls were supposed to have been built with chalk blocks weren't they! Maybe JL mentions this in his book.
Just noticed this S .For me a phase in archaeological terms is related a change in use ,which could mean destruction of the an earlier phase so not really the same as a building term . Once again I don't know what is in the book but the earlier understanding was the curvilinear chalk walls noted by Atkinson were considered , in 2007 , to be part of the neolithic construction technique of the mound ."Finer deposits were laid horizontally and revetted by larger chalk rubble forming a crude dry stone wall "
Yes that's very much (I think) how it is explained in Caroline Malone's EH book Avebury (1989) in which there is a superb B&W photo of the chalk walls under excavation at the top of Silbury Hill during the 1969-70 dig, along with the equally good and descriptive drawing of the internal chalk walls.
Actually as EH publications go I think her book is excellent in its layout, quality of photographs, descriptions, information and general readability (is that a word?). When I first ordered it I thought is was going to be just another Avebury guide but it's 141 pages of quality informative reading.
