Resumen Se exponen los resultados del estudio del calendario agrícola y un posible sistema Palabras clave de ceques en la comunidad indígena atacameña de Socaire, norte de Chile. Desde la etnoastronomía etnoastronomía se analizan los fenómenos de pareidolia asociados a la observación pareidolia del cielo y la representación de la topografía del lugar. Los resultados demuestran norte de Chile la existencia de un sistema de líneas o convidos, similar a los ceques del Cuzco, desti- nados a organizar espacio-temporalmente las actividades agrícolas y los principales rituales. Se presentan evidencias arqueológicas que sustentan la hipótesis del culto a los cerros en tiempos prehispánicos, así como elementos de geometría y matemá- tica indígena, que vinculan el uso del cuerpo humano con el concepto de paisaje. El estudio comparativo supone la existencia de patrones psicológicos, no sólo para identificar “astros, constelaciones y topoformas”, sino también para explicar mitos y cosmogonías en el contexto de la astronomía cultural. * Agradecimientos.

A Preliminary Evaluation of Volatiles Content in Melt Inclusion in Monogenetic Centers of the Central Andean Volcanic Zone (Northern of Chile)
Goldschmidt2019 Abstract A preliminary evaluation of volatiles content in melt inclusion in monogenetic centers of the Central Andean Volcanic Zone (Northern of Chile) C. GONZÁLEZ 1*, E.H. HAURI 2, A. SAAL 3, J. WANG 2 AND F. AGUILERA1 1 Departamento de Ciencias Geológicas, Universidad Católica del Norte, Antofagasta, 1270709, Chile. (*correspondence: [email protected]) 2 Department of Terrestrial Magnetism, Carnegie Institution for Science, Washington, DC 20015, USA 3 Department of Earth, Environmental and Planetary Sciences, Brown University, Providence, RI 02912, USA Volatiles in subduction zones are generated during metamorphism of the subduction of the Nazca oceanic lithosphere previously affected by hydrothermal alteration and seawater circulation [1, 2]. In the Central Andean Volcanic Zone (CAVZ) the regional tectonic setting and the heterogenous magma source have controlled the chemistry and isotopic composition of the erupted lavas [3, 4]. These factors could modify the distribution of volatiles along and across the arc (e.g. CAVA. Sadofsky et al., 2008). Across the CAVZ of Northern Chile, there are several Pliocene to Holocene monogenetic mafic centers associated to pyroclastic deposits: Ajata volcano, Porunita, La Luna de Tierra, Poruna and volcan del Inca scoria cones and Cerro Overo maar, with a range in magma composition from basaltic-andesite to andesite (SiO2 53.42 – 60.34 wt%) respectively. We picked Olivine-hosted melt inclusions from the pyroclastic material to determine the composition and distribution of volatiles (H, C, F, S, Cl) in the most primitive magmas. The olivine phenocrysts are subhedral to anhedral, varying from < 1 mm to ~200 µm. The distribution and size of melt inclusion varies between site. -
