This work was carried out as part of the Natural Environment Research Council's geochemical cycling programme. Its aim was to identify the changes taking place in the constituent minerals as Silurian Gwestyn Shale weathers to a humic stagnopodsol soil at Plynlimon, mid Wales. Hand specimen appearance and chemical analyses show that the rock groups present at Plynlimon are not homogeneous. The chlorites in different rocks are also shown to have significantly different chemical compositions, and are seen to be physically intergrown with-mica. Another source of variation is that many of the soils are developed on glacial or periglacial deposits, rather than directly on rock.
