SKp describes P enrichment in speleothems regardless of the process, as similar mechanisms of phosphate co-precipitation may be in operation in biotic and abiotic conditions. The most important implication of our study is that variability in P concentration may be related to diverse processes which can be recognized through petrographic observations and chemical mapping. In particular, there may not be a direct relation between an increase in P concentration and seasonal infiltration as has been found in some previous studies, especially if the source of this element is not the labile phosphate released through leaching during seasonal vegetation dieback in temperate climates.]]> Wed 11 Apr 2018 10:30:22 AEST ]]> Increasing Australian-Indonesian monsoon rainfall linked to early Holocene sea-level rise https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:6875 Tue 19 May 2020 10:48:38 AEST ]]> Evidence for obliquity forcing of glacial termination II https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:7742 Sat 24 Mar 2018 08:41:55 AEDT ]]> The environmental features of the Monte Corchia cave system (Apuan Alps, central Italy) and their effects on speleothem growth https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5267 Sat 24 Mar 2018 07:46:33 AEDT ]]> An environmental model of fluvial tufas in the monsoonal tropics, Barkly karst, northern Australia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3319 Sat 24 Mar 2018 07:23:19 AEDT ]]> Are current models of tufa sedimentary environments applicable to tropical systems?: a case study from the Gregory River https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3320 Sat 24 Mar 2018 07:23:18 AEDT ]]> Enhanced rainfall in the Western Mediterranean during deposition of sapropel S1: stalagmite evidence from Corchia cave (Central Italy) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3317 Sat 24 Mar 2018 07:23:18 AEDT ]]>
