Intertwining volcanoes and society in Chile through arts and interdisciplinary connections
Full text linkThe conceptual distance between nature and society has been a concern within social sciences and interdisciplinary debates. We contribute to this discussion illustrating how arts have played an important role in demonstrating the entanglement of Earth and society through their ability to frame and shape the dynamics of the Earth across sensations. Through an examination of artistic representations in Chile, we seek to show how the proximity of Chilean society to the presence of volcanoes has been eloquently conveyed through various artistic styles across different historical epochs. Our study extends from the birth of the Chilean nation in 1818 to the year 2021, and examines a wide range of artistic representations, that encompass national symbols, image-making techniques, sculpture, art installations, poetry, music, and audiovisual works. Our research represents a pioneering effort to explore the diverse representations of volcanoes in Chile and has uncovered a remarkable diversity of artistic expressions that reflects the deep connection between Chilean society and volcanic processes and landscapes. Ever-present and often breathtaking, volcanoes have served as enduring symbols of national identity and as sources of inspiration for artists of diverse disciplines and aesthetic sensibilities. We illustrate how the arts reveal the relationship between volcanoes and social life and provide the basis for a detailed analysis that explores the temporal and spatial contexts in the representation of volcanoes and the human perception of geological phenomena in Chilean culture.pp.271-29

Evolution of the Tumaco, Atrato, and San Juan basins on a continuous platform along the colombian pacific margin
No full textSeveral authors have interpreted the Colombian Pacific margin as a succession of oceanic terrane accretions, with generation of forearc basins under a compressive-transpressive tectonic regime during the Late Cretaceous-Miocene. New data acquired in the last decade, consisting of reprocessed seismic lines, geological cross-sections, stratigraphic data from wells, and new stratigraphic columns, are analyzed in this study. We suggest that the proposed models of successive terrane accretions are not supported by the new data; rather, the onshore basins were likely controlled by a marine platform from the Late Cretaceous to the Middle-Late Eocene, with reef growth to the end of this period. In the Late Cretaceous, contemporary to the sedimentation stage, effusive magmatism, mainly basaltic, also occurred. Since Oligocene time, the basins were affected by three different tectonic processes. First, during the Oligocene-Early Miocene, an extensional-transtensional event occurred in the Tumaco Basin and San Juan Sub-basin, which produced horst and graben structures and domino faults, along with the emplacement of igneous bodies in the eastern flank of the basins. The Atrato Sub-basin was affected by local reverse faulting towards its eastern edge. Second, during the Mid-Late Miocene, the western side of the Tumaco Basin was uplifted, and transpressive deformation occurred in the San Juan Sub-basin as evidenced by the San Juan and Garrapatas fault systems. Finally, in the Atrato Sub-basin, a transpressional regime is evidenced by the Baudó anticline. Our results suggest there is no evidence of oceanic terrane accretions in the abovementioned basins during the Late Cretaceous-Middle Eocene. Furthermore, we do not see evidence of a subduction system during that period. We conclude that subduction in western Colombia could have begun during the Early Oligocene instead.pp.218-24
