Notes:
Underlying bedrock geology at sample site after Cui et al. (2013).
Abbreviations: ICP, aqua regia extraction with inductively coupled plasma mass spectrometry or
emission spectrometry finish; INAA, instrumental neutron activation analysis; ppb, parts per billion;
ppm, parts per million; wt %, weight percent. Analytical determinations prefixed with "<" or ">" are
below or above that detection level, respectively.
