A combination of water and sediment chemistry was used to investigate carbonate production and preservation in Lake Pumayum Co (altitude 5,030 m a.s.l.), south Tibet, China. We compared the chemical composition of lake water in various parts of the lake with that of input rivers and found that the loss of Ca 2? results from calcite sedimentation induced by evaporation and biogenic precipitation. This is supported by evaporation data from the catchment and d18 O measurements on water. Results suggest that CaCO 3 is the predominant carbonate in this lake.There is a positive correlation in the sediments among concentrations of total inorganic carbon (TIC), Ca, total organic carbon (TOC), and total nitrogen, confirming that most carbonates in sediment are endogenic. The Jiaqu River is the largest inflow to Lake Pumayum Co and has a strong influence on both lake water chemistry and sediment composition. The river and lake bathymetry influence carbonate sedimentation by affecting water flow velocity and growing conditions for macrophytes. Different carbon contents and relationships between TIC and TOC in the two long cores from different depths in the lake reveal that hypolimnetic conditions also influence carbonate precipitation and preservation.

“…input from groundwater into the lake, and biological productivity causing calcite supersaturation through the drawdown of CO 2 during photosynthesis (Kalff 2002). d 13 C values depend on (1) groundwater input that affects the d 13 C of the lake DIC, (2) in-lake productivity, and (3) the mass balance of terrestrial versus aquatic organic matter deposited in the lake (Duston et al 1986;Langmuir 1997;Kalff 2002;Leng and Marshall 2004). Carbonate mineral solubility decreases with decreasing pCO 2 , increasing temperature, and increasing pH (Langmuir 1997).…”

Climate records during the last millennium are essential in placing recent anthropogenic-induced climate change into the context of natural climatic variability. However, detailed records are still sparse in Alaska, and these records would help elucidate climate patterns and possible forcing mechanisms. Here we present a multiple-proxy sedimentary record from Kepler Lake in south-central Alaska to reconstruct climatic and environmental changes over the last 800 years. Two short cores (85 and 101 cm long) from this groundwater-fed marl lake provide a detailed stable isotope and sediment lithological record with chronology based on four AMS 14 C dates on terrestrial macrofossils and 210 Pb analysis. The d 18 O values of inorganic calcite (CaCO 3 ) range from -17.0 to -15.7 %, with the highest values during the period of 1450-1850 AD, coeval with the well-documented Little Ice Age (LIA) cold interval in Alaska. The high d 18 O values during the cold LIA are interpreted as reflecting shifts in atmospheric circulation. A weakening of the wintertime Aleutian low pressure system residing over the Gulf of Alaska during the LIA would have resulted in 18 O-enriched winter precipitation as well as a colder and possibly drier winter climate in south-central Alaska. Also, elevated calcite contents of [80 % during the LIA reflect a lowering of lake level and/or enhanced seasonality (warmer summer and colder winter), as calcite precipitation in freshwater lakes is primarily a function of peak summer temperature and water depth. This interpretation is also supported by high d 13 C values, likely reflecting high aquatic productivity or increased residence times of the lake water during lower lake levels. The lower lake levels and warmer summers would have increased evaporative enrichment in 18 O, also contributing to the high d 18 O values during the LIA. Our results indicate that changes in atmospheric circulation were an important component of climate change during the last millennium, exerting strong influence on regional climate in Alaska and the Arctic.

“…We selected Littlefield Lake for study because it (and its drainage basin) has remained relatively unmodified by human development and because the data needed for carbonate budget calculations have been obtained during several recent studies of water chemistry (Dustin et al 1986), surficial sediment geochemistry (Treese et al 198 1;Owen and Wilkinson 1983), and sediment facies distributions (Murphy and Wilkinson 1980;Treese and Wilkinson 1982). The system is also of historical in- thickness maps (Figs.…”

Littlefield Lake is in a late stage of marl lake evolution characterized by reduced rates of carbonate precipitation. Long and short term carbonate budgets show that the volume of calcite in the lake basin is 3-7 times that expected from annual calcium depletion in the epilimnetic water. This Holocene decrease in carbonate production is also recorded as a gradual increase in the amount of organic and carbonate material in cores from the deep lake basin. Late-stage reduction in carbonate production is evidently a natural consequence of lakeward progradation of littoral marl benches, encroachment of terrestrial vegetation, and reduced colonization by carbonate-producing lake macrophytes.Carbonate-precipitating lakes and associated marl sediment of nearly pure lowmagnesium calcite fill depressions in glacial drift throughout temperate regions of the world. Both the water chemistry and ecology of such lakes have been investigated, primarily to determine the relative importance of physicochemical (e.g. Brunskill 1968Brunskill , 1969Terlecky 1974) and biochemical (e.g. Dean 198 1; Gilbert and Leask 198 1) processes in carbonate precipitation.Despite the obvious and intimate link between these processes and marl generation, lake deposits themselves have received comparatively little attention.In addition to the paucity of sedimentary data, our knowledge of lake evolution is hindered by ambiguities surrounding the long term relation between primary productivity and carbonate formation.Wetzel (1970, 1975) and Manny et al. (1978) found that in marl lakes in Michigan and Indiana, except during early post-glacial sedimentation, when rates of autochthonous organic and carbonate deposition were high, periods
