MIOCENE
Bungobine comprises 6 discrete bodies (A to F) or sub-basinal deposits spread randomly over 50 square kilometres. Bodies A and B are |
higher grade and are thicker lenses; they comprise 90% of the Bungobine resources (BR 6925). |
Oil content is variable, with the highest yields coming from brown algal-rich shales. Modified Fischer Assay results (air-dried samples) |
were up to 220L/t. Water content is also very high (BR 6894). |
Very high organic C concentrations have been found in the chars after retorting. The oil shales are relatively aliphatic, with an average |
H:C ratio of 1.7, and have relatively low N and S contents. The oils are low in tar acid and base content (BR 6889). |
Kaolinite deposits are thought to be too hard and to be contaminated by minor organics and iron oxides. They have a high silica content. |
Their economic potential remains untested. |
The deposits are thought to have resulted from changes in climatic conditions brought about by the stagnation of bottom waters in a |
lacustrine environment and the accumulation and preservation of organic matter. |
