Seven hypotheses proposed for the origin of bedded radiolarian cherts:
(after Hori, R.S; Cho, C; and Umeda, H., 1993, Origin of cyclicity in Triassic-Jurassic radiolarian bedded cherts of the Mino accretionary complex from Japan, The Island Arc, 3, 170-180)

 
 
Diagenetic Process Deposition of clay-Radiolarian mixture with  1. Post depositional separation of clay and silica of Radiolarians.
Depositional Processes  Deposition of clay-Radiolarian mixture with 2. Silica compensation depth (SCD) perturbation removes Radiolarians through dissolving.
Deposition of clay-Radiolarian mixture with 3. Turbidites of clay-Radiolaria mixture and consequent sorting.
Constant deposition of Clay with 4. Episodic and rapid deposition of Radiolaria.
Constant deposition of Clay with 5. Turbidites of Radiolaria.
Constant deposition of Radiolaria with 6. Episodic and rapid deposition of clay.
Constant deposition of Radiolaria with 7. Turbidites of clay
