| Paleocene fossil outcrops abound in the glauconite rich gray clay substrata of the creek banks exposed beneath the deep rich surface soils. |
| Tertiary sediments cause subsidence of the basin substrata 2.3 km below sea level, as a result of the sediment load. |
| Ecologically, mosses break down exposed substrata, releasing nutrients for the use of more complex plants that succeed them. |
| It is the hydrogen ion component that is toxic, affecting cell membranes, acidifying substrata, and leaching metals like calcium. |
| Because there is wide variety among makes of specific substrata as plastics, etc., we recommend that adhesive tests are carried out first. |
| All of the material of this species comprises colonies detached from their substrata and mostly in a poor condition. |
