Abstract:
The results of investigations carried out between 1975 and 1978 are summarized. Based on observed echinoid association the flintstones were assigned to the Upper Middle Turonian. The distribution of elements was determined with nuclear absorption spectrometric methods. The black and red flintstones contain similar amounts of iron but differentiate themselves in the carbon content with the carbon being present only in black flintstones. It is assumed that the red coloration of the flintstone was caused by precipitated iron (Fe2O3) during its genesis. Although the Lower Turonian red flintstones are also present in the North Sea area, only those from Helgoland are analysed In this study.
