Erosion, Transport and Segregation of Pumice and Lithic Clasts in Pyroclastic ¯Ows Inferred from Ignimbrite at Lascar Volcano, Chile
Journal of Volcanology and Geothermal Research 104 (2000) 201±235 www.elsevier.nl/locate/jvolgeores Erosion, transport and segregation of pumice and lithic clasts in pyroclastic ¯ows inferred from ignimbrite at Lascar Volcano, Chile E.S. Caldera,*, R.S.J. Sparksa, M.C. Gardewegb aDepartment of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK bServicio Nacional de Geologia y Mineria, Avenida Santa Maria 0104, Casilla 10465, Santiago, Chile Received 4 November 1998; revised and accepted 4 May 2000 Abstract Investigations have been made on the distribution of pumice and lithic clasts in the lithic rich Soncor ignimbrite (26.5 ka) and the 1993 pumice ¯ow deposits of Lascar Volcano, Chile. The Soncor ignimbrite shows three main lithofacies which grade into one another. Coarse lithic breccias range from matrix poor strati®ed varieties, irregular shaped sheets and elongate hummocks in proximal environments, to breccia lenses with pumiceous ignimbrite matrix. Massive, lithic rich facies comprise the bulk of the ignimbrite. Pumice rich facies are bimodal with abundant large pumice clasts (often with reverse grading), rare lithic clasts and occur distally and on high ground adjacent to deep proximal valleys. In the 1993 pyroclastic ¯ow deposits lithic rich facies are deposited on slopes up to 148 whereas pumice rich facies are deposited only on slopes ,48. Lithic rich parts show a thin pumice rich corrugated surface which can be traced into the pumice rich facies. The high lithic content in the Soncor ignimbrite is attributed to the destruction of a pre-existing dome complex, deep explosive cratering into the interior of the volcano and erosion during pyroclastic ¯ow emplacement. -

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.
