Petrography of Mesozoic and Pleistocene Sands
fines, much silt and clay; some brown root hair and barky organics.
76 - very well sorted, subangular, high and low sphericity, white, pure 939c
quartz, very fine sand with a very few coarse size quartz grains; no pebbles, or
granules; no feldspar; lots of fines; a few black organics, coarse size, and some
brown.
78 - very well sorted, subangular, low sphericity, very fine to fine, quite
pure, 989c quartz, silica sand, whitish colour, with some Precambrian grains; a
couple of medium grained quartz grains; no pebbles of granules; feldspar; lots of
fines; a few black lignite fragments and root hairs.
82 - moderately poorly sorted, angular to subangular, fairly pure, very fine
to medium silica sand with some coarse sand and lignite grains; no feldspar no
ticed; no pebbles or granules; lots of fines; very minor black lignite.
86 - quite poorly sorted, subangular, low,some high sphericity, very fine to
coarse silica sand, 9396 quartz, with Precambrian grains and limestone and
Precambrian granules; bulk is fine sand of quartz with Precambrian; lots of
fines; few black lignite fragments.
87 - whitish colour, fairly well sorted, subangular to subrounded, low
sphericity, very fine to fine pure sand and silt, 989e quartz, with some quartz
and Precambrian very coarse sand and granules; no pebbles; lots of fines; a few
very small black lignite fragments.
88 - well sorted, subangular, low sphericity, whitish, pure, 9896 quartz,
very fine sand with some Precambrian grains, and also some coarse sand grains
or quartz and Precambrian (and of course the lignite fragments); no pebbles or
granules; lots of fines; abundant small black lignite fragments with couple of
brownish root hairs.
89 - poorly sorted, very fine to very coarse, angular to subangular, low
sphericity, silica sand, 989e quartz, with more limestone and Precambrian in
coarser fraction than finer (mostly quartz); no pebbles or granules; lots of fines;
rare tiny black lignite fragments.
91 - poorly sorted, very fine to very coarse, angular to subangular, low
sphericity, silica sand, 909e quartz, the finer sizes being concentrated in silica,
the coarser has Precambrian and limestone and quartz; no pebbles; lots of fines;
no organics.
93 - poorly sorted, subangular, high sphericity, medium to coarse silica
sand, 9796 quartz, with Precambrian and limestone grains and many fines as
matrix, and a few granules and pebbles of quartz, Precambrian, and rounded
limestone; lots of fines, mostly silt size; no organics; ^ mm—carb.20, PC.17,
Bl.PC.6,qtz.26.
95 - moderately well sorted, medium to coarse, angular to subangular,
high, some low sphericity, sand, 9796 quartz, with many Precambrian grains
and some small rounded limestone grains; also a few quartz and Precambrian
granules or small pebbles; no fines; no organics.
97 - moderately sorted, angular to subangular, high, some low sphericity,
medium coarse to very coarse silica sand, 9796 quartz, with many Precambrian
and some limestone rounded grains; is also medium sand (mostly silica) - only a
few pebbles; very few fines; no organics; ^ mm—carb.5, PC.5, Bl.PC.l, qtz.8.
99 - moderately well sorted, subangular, high sphericity, medium to me
dium coarse silica sand, 9596 quartz, with Precambrian and some smaller lime
stone grains; a few Precambrian granules; no pebbles; no fines; possible small
black lignite fragments.
