Re the Carn Goedog spot...To explain a bit further. Re the Carn Goedog spotted dolerite sill -- we can see on the map that it is truncated by a fault that runs more of less N-S along the cwm to the west of the tor. The fault line is assumed to run right across the Preseli ridge, giving rise to the col which is the lowest crossing of the ridge -- this is why the route was used by the drovers and their animals. I have assumed that the sills which extend to the west of this fault, on the northern slopes of Mynydd-bach, are part of the Carn Goedog sill. True or false? There appears to have been no sampling which will help us to answer this question....... But we do know that the sill as shown on the geological map is inaccurate. There are certainly several outcrops of dolerite on the mountainside where there are supposed (according to the map) to be Ordovician sediments.....BRIAN JOHNhttps://www.blogger.com/profile/00413447032454568083noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-13402754947623849802014-09-10T11:46:11.344+01:002014-09-10T11:46:11.344+01:00Myris -- there is not much here that is publishabl...Myris -- there is not much here that is publishable -- certainly nothing new. What I'm doing is applying some careful scrutiny to the published paper and pointing out that the designation of Carn Goedog as the place where the Stonehenge spotted dolerites probably came from seems to be based more upon the fact that it is a PROMINENT HILLOCK than upon incontrovertible geological provenancing.......BRIAN JOHNhttps://www.blogger.com/profile/00413447032454568083noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-62196212760258324572014-09-10T10:41:56.460+01:002014-09-10T10:41:56.460+01:00Pete -- an article that's more than ten years ...Pete -- an article that's more than ten years old?
