Cel
TO TEST INTEGRATED PETROLOGICAL AND GEOCHEMICAL INDICATORS FOR NB, P AND TA ENRICHMENTS IN ALKALINE ROCKS OF S.GREENLAND.
.
THE INTEGRATED STRUCTURAL, PETROLOGICAL AND GEOCHEMICAL INDICATORS DEVELOPED ON SEVERAL ALKALINE COMPLEXES IN AFRICA AND CANADA WILL BE TESTED IN TWO ALKALINE COMPLEXES IN SOUTH GREENLAND: GRONEDAL IKA AND MOTZFELDT.
BESIDES FIELD INVESTIGATIONS IN BOTH AREAS, THE PROJECT WILL BE COORDINATED: WITH THE GEOLOGICAL SURVEY OF GREENLAND AND THE INSTITUTE OF GEOLOGICAL SCIENCES, LONDON.
PETROGRAPHIC STUDIES WILL REVEAL MINERALOGICAL COMPOSITION AND STRUCTURE OF NB, TA AND P ENRICHED ROCKS, FENITIZED ZONES BEING OF PARTICULAR INTEREST.
GEOCHEMICAL STUDIES (MICROPROBE , NEUTRON ACTIVATION ANALAYSIS, SPARK SOURCE MASS SPECTROMETRY) WILL INVOLVE NB, TA, P, ZR, HF, SEE, RB, SC, BA, SR AND GA DISTRIBUTION IN THE PRIMARY ANDIN THE METASOMATRICALLY ALTERED ROCKS AND IN THEIR MINERALS. DEPENDING ON THE RESULTS, THE SUGGESTED INTEGRATED PETROLOGICAL-GEOCHEMICAL INDICATORS WILL BE REFINED.
