In the south, volcanic activity contributed silica to the seawater, which led to the deposition of primary radiolarian [[chert]]s (Calabazar*, Carmita, and Santa Teresa) below the carbonate compensation depth. Whereas noncalcareous detritus was absent over most of the northern area, volcanic-derived clays became increasingly abundant toward the south (Santa Teresa* Formation). The Rana granodiorite high was still active, providing material for the Chaco Azul Formation. The position of the Vinas* type carbonates of the Guajaibon–Sierra Azul belt is problematic. | Except for the Yaguajay* belt along the north coast where platform carbonates accumulated, deep-water [http://www.merriam-webster.com/dictionary/pelagic pelagic] deposition continued during the [[Albian]] to [[Cenomanian]] (93 Ma; [[:file:St58OverviewFG29.JPG|Figure 9]]).
