The aim of the present investigation is to examine the weathering of a number of different basic igneous rooks of Lower Carboniferous age and the soils which are formed upon them. Although the chemical composition of each rock is similar, the textures of the rocks differ, and an attempt, will be made to find out whether this has any effect upon the nature of the derived soils. Conditions of climate, topography, vegetation and time are almost uniform in the genesis of each soil profile examined, and it is therefore expected that the soil constituents should be similar in each case. A study will be made of the effects of weathering on the individual minerals occurring in the parent racks, and the relationship between these minerals and the products which may be formed at their expense. The formation of new products is not restricted to the confined interspaces within the weathering parent material, but also takes place within the soil structure. The chemical environments under these two conditions may be sufficiently different to influence the type of secondary minerals produced. On the other hand, material formed in weathered rock may be modified on entering the soil regime. The properties of these weathering products which characterise the soils will be studied in detail and also the conditions of their formation. The relative stabilities of the different parent minerals under soil weathering conditions will also be investigated in this study of the weathering of basic igneous rocks.
