few fines; no organics; >2 mm—carb.2, PC.7, B1.PC.4, qtz.14.
153 - well sorted, pure, medium grained silica sand with some coarser,
mostly Precambrian, grains; no pebbles or granules; some fines; no organics.
166 - very light grey, slightly silty clay, some sand-size clay balls; lots of
fines; no organics.
167 - very well sorted, well rounded; high sphericity; pure, 999k quartz, fine
to very fine grained silica sand; some light grey slightly silty clay bits, former
laminae; lots of fines; no organics.
168 - very well sorted, well rounded; high sphericity; whitish, pure, 999c
quartz, medium fine silica sand with very fine Precambrian laminae(?); some
fines; no organics.
169 - very well sorted, well rounded; high sphericity; whitish, clean, pure,
9996 quartz, fine to very fine grained silica sand, with a few pyrite grains; some
fines; no organics.
170 - well sorted, well rounded; high sphericity; whitish fine to very fine sil
ica sand, 999c quartz, with some Precambrian grains; also few coarse quartz

171 -moderately sorted, well rounded; high, some low, sphericity; very fine
to medium silica sand with fair number of Precambrian and some sulphide
grains; 959e quartz; lots of fines; no organics; ^ mm—carb.O, PC.5, B1.PC.2,

ite granules; some sulphide grains, balls of sand and fines; some fines; no organ
ics; ^ mm—carb.O, PC.2, Bl.PC.l, qtz.O.
174 - poorly sorted, well rounded, medium to medium-coarse silica sand,
subangular buff limestone and Precambrian pebbles - in sand are coarse sul

mm fraction totally dominated by angular limestone; abundant pebbles and
granules.
175 - medium sorted, mostly well rounded, very fine to fine or fine-medium
silica sand, with some Precambrian grains; fair number of angular buff lime
stone granules and coarse sand-size grains (note presence of limestone boulder
at this level); lots of fines; no organics; no pebbles or granules.
176 - sorted, well rounded, fine grained silica sand with many angular buff
limestone granules and pebbles, and some Precambrian; also some coarse
quartz granules, angular, and Precambrian grains in sand; some fines; no or
ganics; ^ mm—carb.42, PC.l, B1.PC.2, qtz.O.
