Minor Element Geochemistry of Lakemichigan Ferromanganese Nodules
Samples of ferromanganese nodules from several localities in Lake Michigan have been analyzed for their minor element content utilizing neutron activation techniques. The thorium and uranium levels in Lake Michigan nodules exhibit marked dissimilarities with marine nodules. The radium content of these freshwater nodules is substantially higher than the reported marine values. The concentrations...
متن کاملGeochemical mass balances of major elements in Lake Baikal
Major element mass balances for Lake Baikal are calculated with mostly previously published data for soluble fluxes and new, unpublished data for riverine suspended particulate matter chemistry. Physical transport seems to be the most important riverine process. The elements Ca, Mg, and Na seem to be very mobile in the weathering mantle and K and Si seem to be relatively mobile. A comparison of...
متن کاملContinued Investigation of the Light Element Geochemistry of Tagish Lake
Introduction: Preliminary analysis of the light element stable isotope geochemistry of the Tagish Lake primitive carbonaceous chondrite showed that it was a carbonate-rich meteorite containing abundant presolar grains [1, 2]. Tagish Lake seemed to be more carbon-rich than CI chondrites, with over 5 wt. % carbon distributed almost equally between organic and inorganic (mostly carbonate) componen...
متن کاملPalynological study of Lake Kotokel’ bottom sediments (Lake Baikal region)
Pollen and AMSC analyses of bottom sediments from the upper nine meters of the Lake Kotokel’ section were carried out. The regional climate and landscape dynamics during the Late Glacial and Holocene has been reconstructed with an average time resolution of ~120 years. It is shown that the climatic conditions in the Kotokel’ basin during Termination I (~15.5–11 ka) were characterized by short d...
متن کاملClimate Change and the World’s “Sacred Sea”—Lake Baikal, Siberia
L Baikal in southeastern Siberia, the “Sacred Sea,” incites strong emotions and action in Russia. In March 2006, 5000 people in Irkutsk, Russia, protested the proposed construction of an oil pipeline scheduled to pass within 800 meters (m) of Lake Baikal’s shoreline, and, within days, President Putin announced the pipeline would be rerouted outside the lake’s watershed (Cullison 2007). In July ...
