Petrography of Mesozoic <strong>and</strong> Pleistocene S<strong>and</strong>s<br />
125 - moderately sorted, angular to subangular, medium to coarse s<strong>and</strong><br />
with some more rounded fine s<strong>and</strong>; mostly of quartz with Precambrian <strong>and</strong><br />
limestone; few fines; possible few tiny lignite fragments.<br />
127 - poorly sorted, angular to subangular, fine to coarse s<strong>and</strong> of quartz,<br />
Precambrian <strong>and</strong> some limestone; with some subangular Precambrian <strong>and</strong><br />
rounded limestone pebbles; few fines; no organics.<br />
129 - moderately well sorted, granular, very coarse s<strong>and</strong> of quartz <strong>and</strong> Pre<br />
cambrian with less Paleozoic (noticeable, angular, fresh, K feldspar), some sul<br />
phides; with a matrix of poorly sorted fine to medium silica s<strong>and</strong>; angular to su<br />
bangular, though limestone tends to be subround; some pebbles; very few fines;<br />
no organics; ^ mm—carb.51, PC.33, B1.PC.23, qtz.40.<br />
132 - moderately poorly sorted, angular, low sphericity, fine to medium<br />
coarse silica s<strong>and</strong>, 9896 quartz, with some Precambrian <strong>and</strong> a few tiny lime<br />
stone grains; few fines; no organics.<br />
134 - moderately sorted, very fine to medium coarse, subangular, quartz<br />
s<strong>and</strong> with a fair number of limestone <strong>and</strong> Precambrian grains; lots of fines;<br />
some pebbles; slight possibility couple tiny lignite fragments, may be shale;<br />
^ mm—carb.20, PC.17, Bl.Ss.8, qtz.16.<br />
138 - moderately poorly sorted, angular to subangular, fine to medium<br />
coarse grained s<strong>and</strong>, 989c quartz, with many Precambrian <strong>and</strong> buff limestone<br />
grains; high sphericity; some carbonate cement fragments; some pebbles; not<br />
much fines; no organics; >2 mm—carb.33, PC.15, Bl.Ss.7, qtz.10.<br />
