Soil studies in relation to geology in an area in north-east Scotland: Part I. The mineralogy of the soil parent materials

Abstract

1. An account is given of the distribution of four separate boulder clays, which form the parent materials of the soils of eastern Kincardineshire.2. The mineral composition of the fine sand fractions of the boulder clays is given.3. The boulder clays, notwithstanding colour similarities, have been shown by mineralogical examination to be distinct.4. The middle boulder clay, largely influenced by rocks of Old Red Sandstone age, is shown to have a higher proportion of ferromagnesian silicate minerals than soils from glacial drifts similarly derived elsewhere in Scotland.
