Is it possible that the Ti/Al ratio in the shale database (SGP?) is simply a function of hydrodynamic sorting between Ti-rich heavy minerals (especially rutile), expected to partition more into the silt or sand-sized fraction, versus Al-rich clay minerals? In the Mississippian Bowland Shale (UK) - immature siltstones (heavy mineral-rich) exhibit higher bulk Ti/Al compared to time-equivalent fine-grained mudstones.
