Figure F6. Percentages of major radiolarian families in the Zone RP-15 diatom-rich unit. Coccodiscids are distributed without general trend, the theoperid content slightly increases, and actinommids seem to react as a response to the diatom deposition. Artostrobids probably also depend on the occurrence of diatoms, with maximum contents at the beginning and in the terminal phase of diatom deposition.
