Abstract
Description
El uso de la piedra como material de construcción fue muy raro en Buenos Aires hasta mediados del siglo XIX, a excepción principalmente de algunas obras de infraestructura pública como calles y veredas. Actualmente se conservan muy pocas de esas veredas depiedra que, en general, sobrevivieron como relictos junto a monumentos históricos. Se trata de las denominadas Lajas de Hamburgo, aludiendo al puerto desde donde supuestamente eran despachadas. Los análisis hechos sobre distintas muestras de antiguas veredas mostraron una composición mineralógica y características petrográficas idénticas a la de las lajas que se extraen en las canteras de las Sierras Bayas en Provincia de Buenos Aires desde la segunda mitad del siglo XIX. Los resultados obtenidos refuerzan nuestra hipótesis de que la denominación Lajas de Hamburgo referiría a materiales que inicialmente pudieron haber sido importados desde dicho puerto pero que luego fueron reemplazados por la producción local.
Stone was rarely used as a building material in Buenos Aires before the middle 19thcentury, except mainly for some public infrastructure such as streets and sidewalks pavement. Nowadays very few of these stone works have survived, and the only examples known are mostly associated with Historical Monuments. In all these cases the material is known as "Slabs from Hamburg", alluding to the port from where they were supposedly dispatched. The different analyzes carried out on several samples show a mineralogical composition and petrographic characteristics which are identical to the slabs quarried at Sierras Bayas (Province of Buenos Aires), since the second half of the 19thcentury. These results support the hypothesis that the name Lajas de Hamburgowould refer to materials that initially couldhave been imported from those German port, but they were later replaced by stones of local production.
