Detecting Compositional Variations in Fine-Grained Sediments by Transmission Electron Microanalysis
Clay material, by definition, is composed of very small particles which are difficult to separate out individually. This initially delayed the identification of the mineral constituents of soils and fine-grained sediments although ‘the ancients’ were able to identify varieties of ‘earths’ by the properties they exhibited (Theophrastus, ca 300 BC, in Mackenzie, 1975) and subsequently these differences were found to be expressions of minera-logical variations.
