摘要: Summary Thin silty deposits cover large areas of north-east Norfolk, occurring mainly on gently sloping and flat plateau sites the floors valleys cut in glacial deposits. Particle size geographic distribution suggest that silt is windblown. The mineralogical composition fraction resembles Hunstanton Till, suggesting most deposit was derived as loess from outwash Weichselian glacier. However, at some localities sand clay components were derived, least partly, subjacent sediments pre-Weichselian age. strongly affects pattern soil types sometimes growth crops.
