9614405 De Silva It is proposed to conduct a petrological and geochemical study of the volcanic products of the little-known but potentially globally significant 1600 A.D. eruption of Huaynaputina (southern Peru). This eruption resulted in complete destruction of the local communities and caused a breakdown of the socioeconomic fabric over a large area of southern Peru for over a century. On a broader scale, the magnitude of this eruption is consistent with previous speculative correlations with major perturbations of the environment in the early 17th century recorded in proxy records. Specific objectives of this study are to elucidate the nature and magnitude of the eruption, characterize and decipher the petrological and geochemical properties of the magma, and assess the possible global impact of the eruption. These objective will be realized through a multi-faceted approach involving field mapping, documentation and sampling of products, physical volcanology and bulk through microscale petrology and geochemistry. A particular effort to evaluate the pre-eruption volatile budget from studies of glass inclusions in phenocrysts will also be made.

9614405 de Silva提议对鲜为人知但可能具有全球意义的全球意义的火山产品进行岩石学和地球化学研究。 这次喷发导致了当地社区的彻底破坏，并导致了一个多世纪以来秘鲁南部大片地区的社会经济结构破裂。 在更广泛的范围内，这次喷发的大小与代理记录中记录的17世纪初期的主要扰动与以前的投机性相关性一致。 这项研究的具体目标是阐明喷发的性质和大小，表征和破译岩浆的岩石学和地球化学特性，并评估喷发的全球影响。这些目标将通过涉及现场映射，文档和产品采样，物理火山学和大量通过微观岩石学和地球化学的多方面方法来实现。 还将制定一项特殊的努力，以评估对玻璃夹杂物研究的爆发前的波动预算。
