Drainage reorganization during breakup of Pangea revealed by in-situ Pb isotopic analysis of detrital K-feldspar

Tyrrell, Shane ; Haughton, P. D. W. ; Daly, J. Stephen (The Geological Society of America, 2007-11)

The Pb isotopic composition of detrital K-feldspar grains can be rapidly measured using laser ablation MC-ICPMS. The feldspar Pb signal can survive weathering, transport and diagenesis, and careful targeting avoids problems ...
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 ...
Sedimentology, sandstone provenance and palaeodrainage on the eastern Rockall Basin margin : evidence from the Pb isotopic composition of detrital K-feldspar

Tyrrell, Shane ; Souders, A. Kate ; Haughton, P. D. W. ; Daly, J. Stephen ; Shannon, Patrick M. (The Geological Society of London, 2010)

The Rockall Basin, west of Ireland, is a frontier area for hydrocarbon exploration but currently the age and location of sand fairways through the basin are poorly known. A recently developed provenance approach based on ...
