Thirty five elements were determined by synchrotron radiation X-ray fluores
cence analysis (SRXRF) and instrumental neutron activation analysis (INAA)
in aeolian and river suspension, performed accordingly, in winter and summe
r seasons in Baikal Region. By means of double rate setting (normalization)
for Sc, comparative (with Clarke values) analysis for clays was executed.
With few exceptions, spectra of elements resistant to physical and chemical
weathering in river suspension of modern Baikal silt and clays are similar
to each other. Aeolian suspension (snow samples) over the Southern Water A
rea of Baikal Lake, on the whole differs from the others by lower normalize
d values of alkaline and alkaline-earth elements, Mn, Fe, Ni, and Zn, and b
y higher values of Cr, As, Pb, and Sb (anthropogenic influence). As far as
spectra of rare and rare-earth elements are concerned, aeolian suspensions
have relatively constant distribution spectrum. (C) 2001 Elsevier Science B
