Este trabajo reconstruye los diferentes mapas de la ciudad que se van trazando a partir de los itinerarios, las localizaciones y los vínculos de los personajes en algunas novelas argentinas aparecidas en la década de 1880, con el objeto de demostrar que esta cartografía urbana es el emergente de una estructura de sentimiento legitimadora de la hegemonía de una clase y que se conecta, a su vez, con la necesidad de reducir y simplificar las relaciones sociales cada vez más problemáticas de la ciudad moderna.

The technique of 40Ar-39Ar step-heating dating was applied to three rock samples from core of DSDP Site 443, one sample from Site 445, and four samples at Site 446. All sites were drilled during DSDP Leg 58. At Site 443 (Shikoku Basin), about 116 meters of basalt basement was drilled. Three samples were chosen for dating from different levels in the basalt; two samples are aphyric basalt, and the other is subophitic dolerite. At Site 445 (Daito Ridge), no basement rock was drilled; however, conglomeratic sandstone was cored in the lower part of the hole. 40Ar-39Ar dating was applied to a basalt pebble in the conglomerate. At Site 446 (Daito Basin), the lower cored sequence is clay stone interlayered with 16 basalt sills. Four samples were chosen from sills at different levels.
