Moose River Basin
101 - well sorted, angular to subangular, fine, pure silica sand with some
limestone and Precambrian and some medium quartz grains; some fines; few
tiny black, brown, lignite fragments; more than sample 103.
103 - very well sorted, angular to subangular, very fine grained, pure silica
sand, with some Precambrian and dolomite but not much, few fines; some tiny
black lignite fragments; not as much as sample 105.
105 - poorly sorted, angular to subangular, very coarse sand to medium
pebbles size gravel of Precambrian, some limestone, some quartz (minor sul
phide), with matrix of poorly sorted very fine to medium sand; almost no fines;
abundant lignite in all sizes; black lignite pebbles, also very black carbona
ceous clays.
107 - moderately sorted, angular to subangular, medium fine to medium
silica sand with some Precambrian and few limestone and couple quartz gran
ules; most of medium sand and coarser grains are quartz; some fines; abundant
black, some brown lignite fragments, often of coarse sand size; also very black
carbonaceous clays.
109 - moderately sorted, angular to subangular, fine to medium silica sand
with some Precambrian and limestone grains, and some quartz granules, and a
few limestone and Precambrian small subround pebbles; almost no fines; some
lignite fragments and small pebbles.
Ill - well sorted, angular to subangular, fine to fine medium silica sand
with some Precambrian and limestone grains and lignite fragments; no peb
bles; no fines; some black and grey lignite fragments.
113 - rather poorly sorted, subangular to subround, granular to medium
pebble gravel of light and black Precambrian, carbonate, and not much quartz
at all; also lignite pebbles showing good woody character; some moderately
sorted fine silica sand matrix though not much; fines; some black lignite peb
bles.
115 - moderately poorly sorted, angular to subangular, very coarse sand to
granular gravel of quartz, Precambrian, limestone with many rounded lime
stone and black Precambrian and angular Precambrian small pebbles only
trace of dark grey fines; few pebble-size black lignite frags.
117 - moderately sorted, angular to subangular, very coarse sand to granu
lar gravel (quartz and Precambrian, with some limestone) with many small
pebbles of angular quartz and Precambrian, and rounded carbonate; black Pre
cambrian tend to round more than felsic; no fines; no organics.
118 - poorly sorted, angular, impure, fine to very coarse sand of quartz, Pre
cambrian, rounded limestone with a few small Precambrian pebbles almost no
fines; no organics.
119 - moderately well sorted, angular to subangular, fine to fine medium
silica sand, with some Precambrian and small limestone grains, and some
coarse and very coarse sand grains; no pebbles; no fines; few very tiny black lig
nite fragments.
121 - moderately well sorted, angular to subangular, medium to coarsegrained
sand with many angular Precambrian and fair number subround lime
stone grains; no pebbles; no fines at all; possible few black lignite fragments.
123 - well sorted, subangular, medium fine, fairly pure silica sand, with
some limestone and Precambrian grains, and also some Precambrian and
quartz coarse sand grains; no pebbles; almost no fines; no organics.
