Ti is carried in silt and in fine sand fractions during transportation. Thus, if the the ratio of Ti/Al increases, grain size becomes coarser and we often use this as a parameter of aridity or terrigeneous flux.Also, the ITCZ shows southward migration, which is coherrent with the decrease in the monsoonal precipitation (Indian Summer MOnsoon {ISM}). Does, the curve of Ti% v/s Age has some effect to decouple the shift in the ITCZ as well?
