silt

Comparing the qualitative results to typical features of marine shales, lacustrine shales are often differentiated by (1) thin recurring (seasonal) laminae [55, 56]; (2) siltier layers, particularly rich in albite and carbonate (dolomite/ankerite); (3) no/little presence of calcareous fossils [18, 21, 57] or framboidal pyrite [25, 58]; (4) overall relatively low visible porosity; and (5) relatively low visible OM porosity for these high maturities.

Various researchers have shown that the risk of excessive deep drainage is greatest with the siltier Wilga and Byron soil profiles associated with the Trangie Cowal (Willis and Black 1996; Willis et al.

They modify the local tidal currents and ambient wave action and, together with the siltier sedimentary units, offer suitable habitat for shellfish.

Fayum L-1x well, drilled in 400 m of water 35 km offshore, tested 21 MCF/d of gas from the main target zone and 6 MCF/d siltier zone.

Group C contained crabs caught in the siltier southern strata and nearby channel (strata 1, 2, and 9) that consumed mainly M.

The mortality and reproductive failure of mussels in reservoirs has been traced to a number of causes, including siltation, which causes direct mortality, (42) elimination of critical host fish species that can no longer tolerate the new reservoir flow conditions, reduced dissolved oxygen at the significantly deeper water depths, reduced temperatures at the deeper water depths, disease, and the inability of juvenile mussels to find suitable substrate in the much siltier and muckier bottom of the reservoir.

On average, forb species with wider leaves occupied shadier, siltier microsites [ILLUSTRATION FOR FIGURE 4 OMITTED], as expected from between-habitat comparisons elsewhere and from economic theory (Givnish 1987, 1988).

The lower flats ("Flats: lower") were generally wetter and consisted of coarser substrates than the upper flats ("Flats: upper"), which were siltier and in some places covered by a distinctive algal mat.
