RESUMO: No presente artigo, revisita-se a coleção de amostras geológicas
recolhidas pelos oficiais da Marinha Portuguesa Hermenegildo Capelo e
Roberto Ivens, durante a famosa viagem De Angola á Contracosta.
Confiadas à Comissão dos Trabalhos Geológicos, aquando do regresso dos
exploradores, as amostras foram classificadas por Nery Delgado e Alfredo
Bensaúde, tendo sido incorporadas no acervo do Museu Geológico e, na
década de 1990, transferidas para a Litoteca do LNEG, polo de Alfragide,
onde foram objeto de um trabalho de reacondicionamento e inventário,
revisto e ampliado recentemente. Para além do seu valor enquanto
testemunho das explorações científicas empreendidas pelos portugueses
em solo africano, estas amostras, analisadas em conjunto com o texto
homónimo assinado pelos dois exploradores, ilustram muitas das
diferentes litologias atravessadas, dos cratões africanos e das orlas
sedimentares.
ABSTRACT: This paper revisits the geological collection assembled by Portuguese Navy officers Hermenegildo Capelo and Roberto Ivens, during the famous Africa crossing (1884-85) “From Angola to the opposite coast”. Deposited at the museum of the Geological Survey in Lisbon, upon the return of travellers, the samples were classified by Nery Delgado and Alfredo Bensaúde. In the 1990s, the museum's African collections were transferred to the LNEG – Alfragide core library (Litoteca), where they were the object of a reconditioning and inventory, recently reviewed. In addition to their value as testimony to the scientific explorations undertaken by the Portuguese travellers in Africa, these samples, interpreted together with the homonymous text signed by the two explorers, illustrate many of the different lithologies crossed, from the African craton and to sedimentary borders.
