Autor: Giancarlo Barabino, Celso B. Gomes, Gianbosco Traversa

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 79, Iss 3, Pp 473-501 (2007)

Chemical data of heavy minerals from Lages diatremes in southern Brazil have been studied with the aim of characterizing the sample source(s). Three groups of minerals are recognized: I) aluminian-chromian pyroxene, pyrope garnet and chromian spinel,

The Pariquera Acu K-alkaline complex and southern Brazil lithospheric mantle source characteristics

Autor: S. D’Acquarica, Celso B. Gomes, Pietro Brotzu, L. Morbidelli, Gianbosco Traversa, C. Garbarino, Excelso Ruberti

Four of the most important K-alkaline magmatic complexes of southern Brazil are associated with two main NW-trending structures. The Lages occurrence is linked to the uplift of a large crustal block, the Lages Dome, tectonically controlled by old NW-
