It is mostly constituted by nepheline-bearing syenites, with biotite or aegirine, and by alkaline dykes. The dykes are more abundant in the biotite-nepheline-syenites and are the most evolved rocks of the massif. Recently, a blue sodalite-syenite dyke has been identified in the southwest part of the massif, hosted by biotite-nepheline syenites. The blue syenites have been exploited as dimension stone. The dyke has magmatic sodalite that crystallized between 720 ± 9 Ma and 732 ± 24 Ma (Pb-PbZr), and cuts the magmatic foliation of the host syenite, imprinting a metasomatism with sodalite formation. Petrographic data indicate that the magmatic sodalite formed during the late stages by a volatile rich magma (500–600o C). The high contents (ppm) of Zr (>5,000), Hf (141), Ta (169), U (74) and F (1200) of the blue syenite suggest that it represents a highly evolved product from differentiation of the nepheline-syenitic magma.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2011-09-02T14:58:14Z No. of bitstreams: 1 7307.pdf: 2079378 bytes, checksum: 079c988b9eab2d27c40c44a1f852765f (MD5)Made available in DSpace on 2011-09-02T14:58:14Z (GMT).
