Calibrated geochemical dataset for selected elements in stream sediment and soil samples, North Greenland

This dataset comprises calibrated geochemical data from stream sediment and soil samples collected in North Greenland between 1978 and 1999, supplemented by extensive reanalyses in 2011. The dataset includes selected elements relevant for the evaluation of zinc mineralisation: CaO, K₂O, Ba, Cu, Sr and Zn.

A total of 2,469 stream sediment samples and 204 soil samples were included. The analytical values represent the most reliable results following systematic quality control and calibration procedures designed to eliminate bias between analytical methods and analytical periods, as described in Thrane et al. (2011).

All values below detection limit are coded as 0 in the dataset. The dataset supports regional assessment of geochemical patterns and mineral potential in North Greenland.

Statement

Stream sediment and soil samples were collected in North Greenland between 1978 and 1999 following established regional geochemical sampling procedures (Steenfelt, 1999). Samples consisted of approximately 500 g sediment collected from stream beds and banks, or soil from areas without streams. Grain-size fractions <0.1 mm or <0.075 mm were analysed.

In 2011, a large number of samples were reanalysed. The compiled dataset was subjected to systematic quality control and calibration procedures to remove analytical bias between different methods and time periods, as described in Thrane et al. (2011). The final dataset represents a harmonised selection of the most reliable analytical values.
