La Galite Archipelago (Tunisia, North Africa): stratigraphic and petrographic revision and insights for geodynamic evolution of the Maghrebian Chain

The location of the La Galite Archipelago on the Internal/External Zones of the Maghrebian Chain holds strong interest for the reconstruction of the geodynamic evolution of the Mesomediterranean Microplate-Africa Plate Boundary Zone. New stratigraphic and petrographic data on sedimentary successions intruded upon by plutonic rocks enabled a better definition of the palaeogeographic and palaeotectonic evolutionary model of the area during the early-middle Miocene. The lower Miocene sedimentary units (La Galite Flysch and Numidian-like Flysch) belong to the Mauritanian (internal) and Massylian (external) sub-Domains of the Maghrebian Chain, respectively. These deposits are related to a typical syn-orogenic deposition in the Maghrebian Flysch Basin Domain, successively backthrusted above the internal units. The backthrusting age is post-Burdigalian (probably Langhian-Serravallian) and the compressional phase represents the last stage in the building of the accretionary wedge of the Maghrebian orogen. These flysch units may be co-relatable to the similar well-known formations along the Maghrebian and Betic Chains. The emplacement of potassic peraluminous magmatism, caused local metamorphism in the Late Serravallian-Early Tortonian (14–10 Ma), after the last compressional phase (backthrusting), during an extensional tectonic event. This extensional phase is probably due to the opening of a slab break-off in the deep subduction system. La Galite Archipelago represents a portion of the Maghrebian Flysch Basin tectonically emplaced above the southern margin of the “Mesomediterranean Microplate” which separated the Piemontese-Ligurian Ocean from a southern oceanic branch of the Tethys (i.e. the Maghrebian Flysch Basin). The possible presence of an imbricate thrust system between La Galite Archipelago and northern Tunisia may be useful to exclude the petroleum exploration from the deformed sectors of the offshore area considered.

RELIGIOUS SCULPTURE OF THE CHILOÉ ARCHIPELAGO, FROM THE 17TH TO THE 21ST CENTURY

Despite its central role in religious life of the region, the sculptural tradition of the Southern Chilean Chiloé Archipelago, ranging from the 17th century to the present day, has been vastly understudied. Isidoro Vázquez de Acuña’s 1994 volume Santeria de Chiloe: ensayo y catastro remains the only catalogue of Chilote sculpture. Though the author includes photographs of a vast array of works, he does not attempt to place the sculptures within a chronology, or consider their place within the greater Latin American context. My thesis will place this group of works within a chronological and geographical context that reaches from the 16th century to the present day, connected to the artistic traditions of regions as far afield as Paraguay and Lima. I will first consider the works brought to the Archipelago by religious orders – the Jesuits and Franciscans – as well as influences on artistic style and religious culture throughout the 17th, 18th and 19th centuries. I will focus in particular on three works generally considered to be from the 17th and 18th centuries – the Virgin of Loreto at Achao, the Saint Michael at Castro, and the Jesus Nazareno of Caguach – using visual analysis and sifting through generations of primary and secondary sources to determine from where and when these sculptures came. With this investigation as a foundation, I will consider how they inspired vernacular sculptural expression and trace ‘family trees’ of vernacular works based on these precedents. Vernacular artistic traditions are often viewed as derivative and lacking in skill, but Chilote sculptors in fact engaged with a variety of outside influences and experimented with different sculptural styles. I will conclude by considering which aspects of these styles Chilote artists chose to incorporate into their own work, alter or exclude, artistic decisions that shed light on the Archipelago’s religious and cultural fabric.

Late-Holocene Mass Movements in High Arctic East Lake, Melville Island (Western Canadian Arctic Archipelago)

East Lake, located at Cape Bounty (Melville Island, Canadian High Arctic), was mapped using a high-resolution swath bathymetric sonar and a 12 kHz sub-bottom profiler, allowing for the first time the imaging of widespread occurrence of mass movement deposits (MMDs) in a Canadian High Arctic Lake. Mass movements occurred mostly on steep slopes located away from deltaic sedimentation. The marine to lacustrine transition in the sediment favours the generation of mass movements where the underlying massive mud appears to act as a gliding surface for the overlying varved deposits. Based on acoustic stratigraphy, we have identified at least two distinct events that triggered failures in the lake during the last 2000 years. The synchronicity of multiple failures and their widespread distribution suggest a seismic origin that could be related to the nearby Gustaf-Lougheed Arch seismic zone. Further sedimentological investigations on the MMDs are however required to confirm their age and origin.

Sinto, logo penso: o estímulo-reflexão em Fernando Pessoa, ortónimo

A elaboração deste trabalho visa o esclarecimento de uma situação na poesia de Fernando Pessoa na qual um estímulo conduz a uma reflexão. Para a explicar definiram-se, primariamente, estímulo e reflexão, aplicando estes conceitos, posteriormente, à poesia pessoana. Com o apoio de obras de vários teóricos pessoanos e análise de alguns poemas da obra de Pessoa, ortónimo, verificou-se, então, que este processo é recorrente na sua poesia, servindo mais regularmente de propulsores para a reflexão os estímulos visuais e auditivos. Além disso, pode-se também afirmar que o objetivo deste processo visava a transformação da sensação em arte.

Luz e sombra em mensagem de Fernando Pessoa

A Mensagem de Fernando Pessoa é uma obra marcada por uma forte riqueza simbólica e com inesgotáveis potencialidades interpretativas. Neste caso, analisou-se o contraste luz/sombra, considerando- se que o Quinto Império é anunciado como teatro do dia claro e o sebastianismo que percorre a obra é mistério e nevoeiro. Observado o valor simbólico que pode ser atribuído a estes termos e analisadas as ocorrências de vocábulos que remetem para eles, concluiu-se que existe um elevado número de ocorrências de vocábulos associados à luz e que esta se relaciona com o heroísmo, o conhecimento e o Quinto Império. A sombra que atravessa a obra remete para o desconhecido, o perigo e, também, para o que, estando oculto, pode ser desvendado. Associa-se, deste modo, ao mito sebástico.
