Rees-Davis

The reason for this difference is as follows. For most REEs, such as lanthanum, the evaporation reaction is H2 + LaaOs — 2LaO - - H2O for cerium, it is H2O - - Ct20j, — 2Ce02 + H2. Thus, as hydrogen pressure is increased, lanthanum and most other REEs become more volatile and cerium becomes more refractory under very low pressures (as in vacuum experiments), cerium is significantly more volatile than the other REEs (Davis et al., 1982).

Figure 11, Utilization of soapstone by Eskimos on the central Labrador coast during the Middle Dorset period (200-600AD), The letters in circles (O) are the four quarries from which samples have been analyzed. The letters refer to the letters used in Figure 12 where the characteristic REE patterns are shown. The quarries near O k and Davis Inlet were utilized locally and in the Nain region. In addition material from northern Newfoundland (L) is found in this region as well as many samples for which the quarries have not been identified,...
