...Allen George Davis, B.SC. M.SC. PH.D Summary Calculation of the true clay-mineral content of samples of Keuper Marl analysed has shown that much of the clay content has been aggregated into silt-size units. This aggregated structure accounts for the large range of measured Activities of the Marl...

...P. T. Sherwood Abstract AUTHOR'S REPLY: Davis, Birch & Chandler raise a number of points which I shall deal with in order of importance: (1) They state that, “they see no reason to depart from the B.S. procedures for index [plasticity] tests on Keuper Marl”, and elsewhere they quote a sentence...

...J. D. Coleman Abstract From J. D. COLEMAN: I write to support and amplify the conclusions (p. 54) of this author concerning the fabric of African red clays and Keuper Marl. It is clear that: (1) The properties of undisturbed engineering soils may differ from those of a simple mixture having...

...Allen George Davis, B.SC. PH.D. Summary Previously, it has been suggested that the existence of a variable clay mineralogy was responsible for the anomalous engineering behaviour of Keuper Marl. Using x-ray diffraction techniques and chemical analyses, it is shown here that 80 per cent...

...Michael John Dumbleton, B.SC. PH.D. A.INST.P. F.G.S. Summary African red clays and Keuper Marl are materials of contrasting origin and mineralogical composition. The red clays are residual soils produced by weathering of rocks at the land surface under relatively high temperature and rainfall...

...Philip Thomas Sherwood, B.SC. F.R.I.C. Summary This paper describes the results of soil classification tests carried out on African red clay soils from Kenya and soils from the Keuper Marl formation in England. It shows that in both groups of soils aggregations of clay particles can occur and give...

...J. D. Cornwell Abstract The directions of magnetization of samples from two sites in the Devonian Ashprington volcanic series, Devonshire, are similar in spite of the difference in the dip of the lavas. They are close to the mean direction for the Keuper marls and it is concluded that they resulted...

... and are overlain unconformably by the middle Triassic Muschelkalk dolomites which are in turn overlain by the upper Triassic Keuper marls. The discordance of the Mesozoic on the Carboniferous and the similarity between the upper- and lowermost beds in the basin suggest that the Carboniferous beds represent a fold...
