| The other two silicates are possibly an amphibole and a member of the smectite group. |
| Clay minerals are mainly illite and chlorite, with only traces of smectite, vermiculite and kaolinite. |
| The clay is composed of illite and kaolinite, with minor amounts of chlorite and smectite. |
| The lake may have dried up or nearly dried up periodically, producing outward concentric zones of albite, analcime, clinoptilolite, and smectite. |
| The limestone-dolomite breccia is characterized by abundant palygorskite, minor sepiolite, rare kaolinite and near absence of smectite. |
| In the presence of kaolinite and illite, aggregate sizes were smaller and sinking rates lower than in the presence of smectite and quartz. |
