Heavy mineral variations in mid-Carboniferous deltaic sandstones: Records of a pre-depositional sediment history?

Sandstone composition is influenced by multiple factors, including acidic weathering, occurring during storage in the hinterland, prior to deposition. This study aims to better understand and constrain how the nature and duration of such pre-depositional factors might impact the final sediment composition. Mid-Carboniferous deltaic sandstones from the Clare Basin, western Ireland, for which depositional environments and provenance are well constrained, are the target of this study.
