Several ages are minimum ages for deglaciation because they record the timing of sedimentary events made possible by the removal of ice.
The tightest age constraints on deglaciation are those derived from cosmogenic nuclide surface exposure dating but for some sites only a single age is available.
Total inventories of Pb, Zn and Cu for the lake basin during the period of active mining were 15,415, 5897 and 363 kg, respectively.
The post-mining trajectories for Pb and Zn project a return to pre-mining levels within 54–128 years for Pb and 75–187 years for Zn, although future remobilisation of metal-enriched catchment soils and floodplain sediments could perturb this recovery.
Internet dating is an increasingly popular way of meeting other people, with a significant (and growing) number of long term relationships now starting via the internet in one way or another.
The pre-mining baseline for metal contamination has been established using sediment cores spanning the past 1500 years and contemporary material obtained through sediment trapping.
A number of absolute age determinations that provide a timeframe for the deglaciation of the last ice sheet in northwest England are reviewed.
Some of the ages are probably too old and are therefore unreliable; some others have large associated uncertainties and are imprecise estimates for the loss of ice cover.
At the Last Glacial Maximum, glaciers in north-western England interacted with an Irish Sea Ice Stream (ISIS) occupying the eastern Irish Sea basin (ISB) and advanced as a unified ice-mass.
During a retreat constrained to 21-17.3ka, the sediment landform assemblages lain down reflect the progressive unzipping of the ice masses, oscillations of the ice margin during retreat, and then rapid wastage and disintegration.
