Fundamental elemental component (total carbon, hydrogen, nitrogen, and sulfur) fluctuations help define the origin, depositional environment, and diagenetic alteration of source materials. To determin
We used stationary XRF spectrometry for analysing elemental composition of bank and streambed samples from Weiße Elster sub-basins (111 grids of 8*8 km). For XRF sample preparation freeze-dried catchm
Species abundance: A = abundant (>100 specimens/sample), C = common (32-100 specimens), F = few (10-32 specimens), R = rare (1-9 specimens), X = present, - = absent.
