Hinterland environments of the Late Jurassic northern Weald Basin, England

چکیده
Reconstructing provenance in sandstones can be challenging, especially when the hinterland palaeogeology is unknown due to burial, diagenesis or weathering of original outcrops. As sedimentary processes alter distribution minerals depositional environment, use multiple methods reduces uncertainties, because, together, they account for depositionally-controlled textural and mineralogical re-distribution a basin. Here, we have applied petrography, X-ray fluorescence geochemistry sedimentology understand shallow marine Corallian with aim deducing palaeogeology, palaeoenvironment sediment within northern parts Upper Jurassic Weald Basin, onshore UK. The had mixed mafic-felsic (intermediate), metasedimentary recycled orogen source. experienced significant physical chemical under humid conditions. were relatively more chemically mature up-dip texturally down-dip. Chemically unstable grains heavy concentrated Heterogeneous, sedimentologically-controlled mineral patterns highlight potential errors which may made deriving source-area maturity. This study as it illustrates combined roles deposition controlling primary that then influenced style burial diagenesis. work presented here emphasizes importance multi-proxy approach improve analysis.
