Ob absolyutnom vozraste porod Anabarskogo dokembriya


, : Ob absolyutnom vozraste porod Anabarskogo dokembriya. Geokhimiya 12(Pages 1145-1151

"The potassium-argon method was used to date pegmatites that cut anorthosites in the Anabar shield at 1.5-1.6 billion years, and coarse-grained granites of the Krayevoi massif at 2.0-2.1 billion years. The age of the anorthosites cannot be specified from the available data, but is less than 1.85 and more than 1.5 billion years.".

The aim of this paper was to statistically evaluate the difference in the distribution of values of anti-Borrelia antibodies (AB) in the samples of probands from high-risk (foresters from Sumava forest) and low-risk (blood donors from Prague) grou...

They concluded that mtD...
