Discussion on a hydrogeological model for the early diagenesis of Late Triassic alluvial sediments
Article Abstract:
The idea that red mudstones of the Late Triassic Mercia Mudstone evolved in a marine environment is highly possible. The same is true for interpreting changes in stable isotopic composition and clay mineralogy. However, the hydrogeological model of the migration of seawater into basin-margin clastics and the evolution of a hypersaline brine in the basin should be studied further. The arid basins have sedimentary properties that should have been considered in developing the hydrogeological model.

Mobility of the high field strength, rare earth elements and yttrium during late diagenesis
Article Abstract:
The Permian sandstones of the Cock of Arran, Scotland, yield authigenic titanite that acts as secondary pore-filling cement.Non-association with in situ alteration suggests titanite crystallization from fluids migrating through porous sandstones. Zr, Nb, P, Ce, Nd, Gd and Y were dissolved in these fluids, yielding high concentrations in the resulting titanite. Intrusion of the adjacent Northern Granite may be associated with such hydrothermal circulation.

Discussion on aluminum loss during sandstone diagenesis
Article Abstract:
A study of the Fulmar Formation, which concluded that large amounts of aluminum have been lost during sandstone diagenesis, has provided some interesting and plausible ideas. However, the data and arguments presented did not support the conclusion because the basic assumptions were not adequately constrained. Thus, a revaluation of the data indicated that such conclusion may have been erroneous.
