Evidence of profuse bark shedding in Dicroidium seed ferns (Umkomasiales) from the Triassic of Antarctica

Polar Research
During the 11th German Antarctic North Victoria Land Expedition in 2015/16, exceptionally well-preserved permineralized Kykloxylon stems—the wood of the iconic Dicroidium plants of the Gondwanan Triassic—were collected from the Middle to Upper Triassic ...

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]

, 2017
The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

‘The Good Couscous That Pleases Us!’: The Meanings of Enduring Imperialist Imagery in Postcolonial French Food Advertising, 1970–2000

Gender &History, EarlyView.
ABSTRACT This article examines a wave of Orientalism‐inspired food commercials that appeared on television in France between 1975 and 2000. Older commercials for couscous were more banal, emphasizing a given product's superiority or affordability. Around 1975, however, there was a concerted shift in the advertising; new spots contained exoticized ...
