Contour maps of data point values representing erratic frequency in the walls reveal classic patterns of fans of erratics. A marked contrast in the rate of decline in the frequency of the two varieties in the walls down-ice from the outcrops is attributed to the difference in the spacing of joints in the two rock types. The action of crushing on the closely-jointed variety during glacial transport is believed to have produced erratics generally too small for wall-building within a short distance of the outcrop, whereas blocks of the more massively-jointed variety are still common in the walls up to 20 km from the source. Divergent flow of erratic-bearing ice is suggested as the main agent responsible for spreading erratics in directions at variance to that of general ice flow. Although inferences about glacial processes are made from the wall data, the restricted size range of wall stones has necessitated careful interpretation of the results.<\/jats:p>","DOI":"10.1144\/sjg14010081","type":"journal-article","created":{"date-parts":[[2010,1,15]],"date-time":"2010-01-15T00:29:39Z","timestamp":1263515379000},"page":"81-86","update-policy":"http:\/\/dx.doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Dispersal of glacial erratics from Lennoxtown, Stirlingshire"],"prefix":"10.1144","volume":"14","author":[{"given":"R.
