Summary
1. | The concentration of the ferric iron oxides was responsible for a reddish-blade turbidity which, in turn, played a major role in the thermal stratification of red strip-mine lakes. | ||||
2. | Owing to the lack of measurable turbidity and as a result of selective absorption of visible solar radiation, other strip-mine lakes appeared blue in color. | ||||
3. | The annual heat budget and the summer heat budget are essentially equivalent under saline conditions. | ||||
4. | Regardless of the physical and chemical conditions of the strip-mine lakes, heat income was a function of the circulating water mass. | ||||
5. | The progressive oxidation and precipitation of the iron oxides is the key to the classification of strip-mine lakes. |
