Mineralogy-based quantitative precipitation and temperature
reconstructions from annually laminated lake sediments (Swiss Alps)
since AD 1580.
Geophysical Research Letters, Vol. 35, L13707, doi:10.1029/2008GL034121
We present quantitative autumn, summer and annual precipitation
and summer temperature reconstructions from proglacial annually
laminated Lake Silvaplana, eastern Swiss Alps back to AD 1580.
We used X-ray diffraction peak intensity ratios of minerals
in the sediment layers (quartz qz, plagioclase pl, amphibole am,
mica mi) that are diagnostic for different source areas
and hydrometeorological transport processes in the catchment.
XRD data were calibrated with meteorological data (AD 1800/
1864-1950) and revealed significant correlations: mi/pl with
SON precipitation (r = 0.56, p < 0.05) and MJJAS precipitation
(r = 0.66, p < 0.01); qz/mi with MJJAS temperature (r = -0.72,
p < 0.01) and qz/am with annual precipitation (r = -0.54, p < 0.05).
Geological catchment settings and hydro-meteorological processes
provide deterministic explanations for the correlations.
Our summer temperature reconstruction reproduces the typical
features of past climate variability known from independent
data sets. The precipitation reconstructions show a LIA
climate moister than today. Exceptionally wet periods in our
reconstruction coincide with regional glacier advances.
