For your eyes too: a new set of images of biological materials from the scientific commissioning of the MOGNO beamline at Sirius [PDF]

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 170-180, January 2026.
From whole specimens to histological level reconstructions, images derived from 3D synchrotron‐based microtomography (SR‐microCT) have emerged as a tool that is revolutionizing a wide range of biological research. This paper presents the first commissioning results from experiments to image the anatomy of small animals and specimens from zooarchaeology

Stratigraphic Relations of the Ipubi Formation: Siliciclastic-Evaporitic Succession of the Araripe Basin [PDF]

Anais da Academia Brasileira de Ciências, 2018
The Ipubi Formation represents the Aptian-Albian siliciclastic-evaporitic succession of Araripe Basin, NE Brazil. This succession comprises siliciclastic rocks (bituminous shales and claystones) and evaporites (gypsum and secondary anhydrite) and represents part of the lacustrine-shallow marine post-rift phase I.

Analogue modelling of basin inversion: the role of oblique kinematics and implications for the Araripe Basin (Brazil)

, 2022
Abstract. Basin inversion is a process that takes place when a sedimentary basin is subjected to compressional stresses and may result in the reactivation of pre-existing faults and/or the localization of deformation along new reverse faults. The Araripe Basin (NE Brazil) is an example of a Cretaceous intracontinental aborted rift with its sedimentary ...

Paleoenvironmental evolution of the Aptian Romualdo Formation, Araripe Basin, Northeastern Brazil

Global and Planetary Change, 2021
Abstract The tectonic evolution of the Equatorial Atlantic Gateway (EAG) throughout the early Cretaceous had global implications. This break-up of western Gondwana has played a significant role in causing, or amplifying, environmental changes due to its influence on ocean chemistry, nutrient distribution, water mass circulation, and bottom waters ...
