... are shown in Figure 1 and summarized in Table 1 . Carbonatites of potential economic importance in the advanced stages of exploration in BC are the Aley and the Upper Fir occurrences (Fig. 1 ; Simandl and Hancock, 2011 ). These carbonatites possibly contain substantial resources of Nb, Ta, and P...

...Roger H. Mitchell Abstract Carbonatites are redefined using a mineralogical-genetic classification and divided into two groups: primary carbonatites, and carbothermal residua. Attention is drawn to the fact that carbonatite is both a petrographic term applicable to a particular rock-type as well...
