Upper Paleozoic in the basin extensively developed fine sandstone,
siltite, argillaceous
siltite, and other tighter sandstone.
The
SilTite [mu]-union from SGE Analytical Science simplifies connecting GC guard columns or columns for 2D GC.
Instead, recent mapping identified the banded
siltite unit of the Apple Creek Formation as the dominant stratigraphic unit in the district.
The Hardscrabble Mountain consists of black phyllite and siltite with volcanic and limestone intervals.
The BC member is composed almost entirely of black quartzose argillite, siltite and phyllite, and includes very minor limy argillites and a few dark grey quartzites.
La formation de Weldon du Carbonifere inferieur (Tournaisien) du Groupe de Sussex, dans le sud-est du Nouveau-Brunswick se compose d'intervalles de mudstone dans des stratifications de
siltite rouge et de gres a grain fin.
