shallow Ap Shallow former ploughsoil 
Auger 2a; ditch 
0-20cm Compact grey, dry calcareous silt loam with common chalk pieces. Ap 
20-40cm Pale brown (10YR 6/3) calcareous silty loam, common chalk pieces, with larger and more 
frequent chalk pieces towards 40cm. Ploughwash (tertiary fill), probably medieval and 
post medieval 
40-55cm Dark greyish brown (10YR 4/2) (reddish hue) moist silty clay, with common small chalk 
pieces. Secondary fill 
c.55-60cm Lens of chalk rubble with many very small chalk pieces with matrix as above, giving way to a 
lens of medium chalk rubble containing visible charcoal pieces on auger. Chalk wash 
primary fill 
60-70cm Medium and small chalk pieces in a soil matrix 
75cm + Chalk rubble - hole terminated. Primary fill 
Auger 2b; ditch 
0-25cm Light brown silty ploughsoil with many small and some medium chalk pieces. Ap 
25-35cm —as above but chalkier, possibly towards base of ploughzone 
35-45cem Light buff silty calcareous fill with varying chalk content (?chalk lenses). ploughwash / 
tertiary fill 
45-98cm Slightly darker silty clay with fewer small chalk pieces, but occasional medium chalk pieces 
and charcoal fragment at 87cm. secondary fill 
98-145cm Becoming increasingly chalkier with depth possibly primary fill or eroded ditch sides
