Lithology <strong>of</strong>thepebble grade materials is largely carbonate but far-travelled,resistant Precambrian materials comprise a sizeable percentage(5) . <strong>The</strong> mineralogy <strong>of</strong>the s<strong>and</strong> fraction (5) is noticeable byits content <strong>of</strong> grey shale <strong>and</strong> materials such as quartz <strong>and</strong> feldspar<strong>of</strong> Precambrian origin . <strong>The</strong> shale is derived primarilyfrom the easily eroded Salina formation <strong>and</strong> increases noticeablysouth <strong>of</strong> the upper contact with the Guelph formation(Figure 3) . <strong>The</strong> increase in Precambrian materials (comparewith pebble grade) is indicative <strong>of</strong> the attrition <strong>of</strong> larger fragmentswith distance. Minor amounts <strong>of</strong> s<strong>and</strong> <strong>and</strong> gravel <strong>of</strong> icecontactorigin are also present .Burford <strong>and</strong> Caledon soils have developed on gravel <strong>and</strong>gravelly s<strong>and</strong> deposits <strong>of</strong> glaci<strong>of</strong>luvial origin . A schematiccross-section including the Gr<strong>and</strong> River <strong>and</strong> Paris moraineshown in Figure 8, illustrates the relationship <strong>of</strong> recent alluviumdeposits to the adjacent glaci<strong>of</strong>luvial outwash <strong>and</strong>morainal materials .Lacustrine sediments form the surface materials <strong>of</strong> much<strong>of</strong>the <strong>County</strong>. Alarge part <strong>of</strong>Burford Township <strong>and</strong> a portion<strong>of</strong><strong>Brant</strong>ford Township are mantled with thick deposits <strong>of</strong> deltaic fine s<strong>and</strong>s . <strong>The</strong>se range in thickness from 10 metres nearHarley to 15 metres near Mount Pleasant <strong>and</strong> 23 metres nearthe <strong>Brant</strong>ford airport . In addition, a thin veneer <strong>of</strong> this s<strong>and</strong>overlies much <strong>of</strong>the remainder <strong>of</strong>the <strong>County</strong>.14
