K-feldspar sand-grain provenance in the Triassic, west of Shetland : distinguishing first-cycle and recycled sediment sources?

Tyrrell, Shane ; Leleu, Sophie ; Souders, A. Kate ; Haughton, P. D. W. ; Daly, J. Stephen (John Wiley and Sons, 2009-11)

Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales and pathways. However, these insights can be obscured by difficulties in geochemically distinguishing or ...
Large-scale, linked drainage systems in the NW European Triassic: insights from the Pb isotopic composition of detrital K-feldspar

Tyrrell, Shane ; Souders, A. Kate ; Daly, J. Stephen ; Shannon, Patrick M. ; Haughton, P. D. W. (The Geological Society, 2012-05)

Pb isotopic data from K-feldspars in Middle Triassic (Anisian) sandstones in the Wessex Basin, onshore southwest UK, and the East Irish Sea Basin, some to the north, show that the same grain populations are present. This ...
