Evaporite karst in Italy: a review
International Journal of Speleology, 2017 Although outcropping rarely in Italy, evaporite (gypsum and anhydrite) karst has been described in detail since the early 20th century. Gypsum caves are now known from almost all Italian regions, but are mainly localised along the northern border of the ...

Evaluation of a modern-analogue methodology for reconstructing Australian palaeoclimate from pollen
, 2016 Quantitative palaeoclimate reconstructions are widely used to evaluate climate model performance. Here, as part of an effort to provide such a data set for Australia, we examine the impact of analytical decisions and sampling assumptions on modern ...

Methods for determining peat humification and for quantifying peat bulk density, organic matter and carbon content for palaeostudies of climate and peatland carbon dynamics [PDF]
Mires and Peat, 2011 Quantitative palaeostudies of climate change and carbon dynamics are reliant on precise and accurate laboratory measurements. Here we present laboratory protocols for the colorimetric determination of peat humification and for bulk density and organic ...

Procedures for extraction and purification of leaf wax biomarkers from peats [PDF]
Mires and Peat, 2011 Palaeoecological and palaeoclimate reconstruction, using leaf wax biomarkers, is a relatively new sub-discipline of peatland science. The ability to process large numbers of samples rapidly for biomarkers makes this type of analysis particularly ...
