Long-term and continuous lake sedimentary records offer enormous potential for interpreting paleoenvironmental histories and for understanding how terrestrial environments might respond to current global warming conditions. However, sedimentary recor

Elemental analysis of ferromanganese formations (first of all, the determination of ore elements) is a necessary stage in the development of ore deposits. A technique for X-ray fluorescence quantitative analysis was proposed for the determination of

The wavelength dispersive X-ray fluorescence method was applied to identify the distribution of major oxides within bottom and peat sediments containing organic matter of up to 70 wt.%. Samples were prepared as glass beads by fusing with lithium meta
