| dc.description.abstract | ABSTRACT: At the core of the Granitic Pegmatite Province of Zambezia in Mozambique, in the Alto Ligonha Pegmatite District, a group of distinct types of pegmatites outcrop and are trapped by the same set of strike slip and overthrust structures. The most frequent are beryllium-rich with some Bi and Nb-Ta oxides (with anomalous contents of W). Their primordial, zoned, inner structure is well developed ā giant crystals of K-feldspar at the intermediate zone are conspicuous, as is rose quartz in huge quantities at the cores. At close proximity, LCT typical pegmatites do occur. On the basis of mineralogy, structure, and cartography, and considering the paragenetic contrasts and the emplacement in the same set of large-scale structures of tectonic transport, it is reasonable to accept that this area corresponds to a material frontier between distinct districts or pegmatite fields. | eng |
| dc.description.abstract | RESUMO: No nĆŗcleo da ProvĆncia PegmatĆtica granĆtica da ZambĆ©zia em MoƧambique, no Distrito PegmatĆtico do Alto Ligonha, aflora um grupo de tipos distintos de pegmatitos veiculados por um mesmo conjunto de estruturas de desligamento e carreamento. Os mais frequentes sĆ£o berilĆferos e bismutĆferos com alguns Ć³xidos de Nb-Ta (com teores anĆ³malos de W). A estrutura interna primĆ”ria zonada estĆ” bem desenvolvida ā apresentam cristais gigantes de K-feldspato na zona intermĆ©dia, assim como quartzo rĆ³seo em grandes quantidades no nĆŗcleo. Na vizinhanƧa imediata ocorrem pegmatitos LCT tĆpicos. Com base na mineralogia, estrutura e cartografia, e considerando os contrastes paragenĆ©ticos e a localizaĆ§Ć£o no mesmo conjunto de estruturas megaescalares de transporte tectĆ³nico, Ć© razoĆ”vel aceitar que esta Ć”rea corresponda a uma fronteira material entre distritos ou campos pegmatĆticos distintos. | por |
