The Canadian Mineralogist (2016) 54 (4): 863–877.
... is occupied by LREE (light rare earth elements) that include lanthanum, cerium, praseodymium, neodymium, and samarium. In natural phases the measured concentrations of HREE, including (formerly yttrium), gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium, do not exceed 0.02...

..., drain. In the upper reaches (headwater), where there are no acid sulphate soils, the REE concentrations were low at all sampling events (e.g. Nd=1.0 to 1.3 μg l −1 ) and the shale-normalized profiles were characterized by peaked middle-REE enrichment (centred on gadolinium) with a secondary maximum...
