Composition of sediments and cores from DSDP Legs 54 and 61-63

The monograph gives results of studies of sediments and rocks collected from D/S Glomar Challenger in the Pacific Ocean. These studies have been based on the lithological facial analysis applied for the first time for identificating genesis of ocean sediments. These results include new ideas on formation of the Earth's sedimentary cover and can be used for constructing regional and global schemes of ocean paleogeography, reconstructing some structures, correlating sedimentation on continents and in oceans, estimating perspectives of oil- and gas-bearing deposits and ore formation. The monograph also gives the first petrographic classification of organic matter in black shales.

¡Me engañaste, me mentiste! La embajada persa a Atenas (Ar. Ach. 61-124) y sus implicaturas frente al público

Atendiendo a la relación establecida entre la comedia y los ámbitos político- legales que la circundan, se ha podido instituir un vínculo entre la ficción cómica y la realidad política de la Atenas clásica que se percibe fundamentalmente en las primeras comedias de Aristófanes. Dentro de Acarnienses podremos entonces determinar un nuevo punto de análisis si consideramos que en las breves declamaciones del persa se cifra uno de los recursos más notorios de la diplomacia estatal: la manipulación ante la asamblea del discurso de los embajadores de una nación por parte de la voz autorizada de la pólis receptora (Ammendola: 2001-2002). Será nuestro propósito abordar un costado diverso de esta escena definiendo su peso específico, aparentemente secundario, en la trama total de la obra. De ese modo nos interesará detectar la verdadera trascendencia del comportamiento del embajador persa respecto de los ciudadanos atenienses representados en la persona del viejo Diceópolis

Age and petrographic characterization of volcanic ash from ODP Leg 198 and Leg 126 sites

In this study of volcanic ash retrieved from Shatsky Rise during Ocean Drilling Program Leg 198, the texture and composition of the volcanic components (glass and crystals) were used to fingerprint ash layers for detailed correlation. Correlations among ash layers in holes drilled at the same site as well as between sites, including sites on different parts (highs) of the rise, were tested. Although high-to-high correlations failed, intrahigh correlations were more successful. Our data suggest a significantly different source for some pyroclastic debris, especially at Site 1208, possibly associated with pumice rafts carried northward from the Izu-Bonin arc by the Kuroshio Current. Other ashes are consistent with rhyolitic to dacitic air fall ash from Asian arc volcanoes. We were not able to texturally distinguish between air fall ash and pumice-raft fallout but suspect that the latter is associated with higher percentages of vesiculated ash components, as we demonstrate occur in more proximal Izu-Bonin pyroclastic deposits.
