Comments on the geologic information

  • RECORD NO. 102 REPRESENTS RARE EARTH OXIDES OF WHICH YTTRIUM IS A MAIN CONSTITUENT. MINERALOGY: ELPIDITE, GITTINSITE, ZIRCON AND ARMSTRONGITE (ZR), PYROCHLORE (NB), GADOLINITE (Y, BE), KAINOSITE AND ALLANITE (Y, REE) AND THORITE (TH).
  • THE COMPLEX IS A GRANITIC PRECAMBRIAN COMPLEX SURROUNDED BY GNEISSES. THE ORE ZONE IS YOUNGER THAN COUNTRY ROCK AND IS COMPLETELY DEFICIENT IN CARBONATES. IT IS AN ELLIPTICAL BODY, ABOUT 30 SQ. KM., INTRUDES APHEBIAN PARAGNEISSES AND AND MIGMATITES. OVERLYING THE DEPOSIT IS A BED OF OVERBURDEN VARYING IN THICKNESS FROM 3 TO 10 M. CONCENTRATIONS OF RARE MINERALS IN VEINS, FLUORITE BRECCIA ZONES OF HYDROTHERMAL ALTERATION, WITHIN AN ALKALINE COMPLEX OF HELIKIAN AGE. [NMIMP, NFLD 66]
