Differential diagenesis



Differential diagenesis is proposed to interpret the alternating cemented and uncemented, fine-grained layers from Pliocene periplatform carbonates of the Great Bahama Bank (Westphal H, Head M J, Munnecke A. 2000).


There are also limestone-marl alternations in Phanerozoic eons, for example, Silurian of Gotland, Sweden(Munnecke A, Samtleben C. 1996). I find a analogous alternation in south China, and I want to find its origin. The difficulty is that the geochemical model. where does dissolusion take place? where does the reprecipitation occur?
