| 11 | Age, dated | Age dated | ka | Odin, G S | The apparent age of the detrital clay fraction is inherited and is probably similar to that of the initial substrate of glauconitization. The apparent ages of the glauconies demonstrate once more the presence of part of the initial radiogenic argon as it might have been foreseen from their level of evolution. The apparent ages cannot be related to the epoch of genesis. | |
