Pompeani, D.P., B.A. Steinman, and M.B. Abbott. 2012.
A sedimentary and geochemical record of water-level changes
from Rantin Lake, Yukon, Canada.
Journal of Paleolimnology, Vol. 48, No. 1, June 2012, pp. 147-158.
DOI: 10.1007/s10933-012-9602-9
A multi-proxy analysis of two sediment cores from Rantin Lake
are used to reconstruct past lake-level changes and to make
inferences about millennial-scale variations in precipitation/
evaporation (P/E) balance in the southern Yukon, Canada between
10,900 and 3,100 cal yr BP. Analyses of calcium carbonate
and organic matter concentration, magnetic susceptibility,
titanium content, dry bulk density, and macrofossils are used
to reconstruct water-level changes. The development of sand layers
and deformed sediments at the deep-water core site (i.e. Core A-06)
prior to ~10,900 cal yr BP suggest that lake level was lower at
this time. Fine-grained organic sediment deposited from 10,600
to 9,500 cal yr BP indicates a rise in lake level. The formation
of an unconformity at the shallow cores site (Core C-06) and the
deposition of shallow-water calcium carbonate-rich facies at the
Core A-06 site between ~9,500 and ~8,500 cal yr BP suggest lower
lake levels at this time. Shallow-water facies gradually transition
into a sand layer that likely represents shoreline reworking during
an extreme lowstand that occurred at ~8,400 cal yr BP. Following
this low water level, fine-grained organic-rich sediment formed
by ~8,200 cal yr BP, suggesting deeper water conditions at core
site A-06. Calcium carbonate concentrations are relatively low
in sediment deposited from ~6,300 to 3,100 cal yr BP in Core A-06,
indicating that lake level was comparatively higher during the
middle and late Holocene. In general, results from this study
suggest that the early Holocene was characterized by high P/E
from ~10,500 to 9,500 cal yr BP, low P/E from ~9,500 to 8,400
cal yr BP, and return to higher P/E from ~8,200 to 3,100 cal yr BP.
STUDY NOTES: Multiproxy sediment data from Rantin Lake, southern Yukon,
covering the interval 10,900 to 3,100 calendar years before
present. Paleoenvironmental proxies measured include
carbonate content, organic matter content, bulk density,
magnetic susceptibility, titanium content, and calculated
lake level index.
Rantin Lake, Yukon: 60.0296°N, 129.0323°W, 720m elevation, ~11m water depth.
