Sažetak
Selected tufa samples from Guangxi Province, China, were analysed in terms of mineralogy, major and trace elements, specific activity and 14C age. The major mineral is calcite varied from 65 to 95%, minor minerals are quartz and dolomire, magnesium carbonate from 0.03 to 1.77%. All samples contain traces of sodium and potassium, iron, titanium, manganese and many other elements. Specific activity of radionuclides 14K, 232Th, 137Cs, 226Ra and 238U showed different concentrations in all samples. 14C age was performed on 5 out of 11 studies samples. On sample originates from Pleistocene and other samples from Holocene.
