RUIZ DE GALARRETA, Alejandro; BARRANQUERO, Rosario; VARNI, Marcelo  e  RODRIGUEZ, Corina Iris. Geology and Hydrolithology of Langueyú Creek Basin, Buenos Aires Province (Argentina). Cienc. docencia tecnol. [online]. 2011, n.43, pp.157-176. ISSN 1851-1716.

The main objective of this study is the geologic characterization of Langueyú Creek Basin and its relation with the hydraulic properties of rocks and sediments. The boundaries and features of the water system in this area are described from a regional analytical and explanatory approach of physical compounds such as stratigraphy, structural geology and geomorphology. From the stratigraphical point of view, the basin is composed by a crystalline basement of Precambrian age and a Cenozoic sedimentary cover. These materials correspond with two hydrolithological fields: the fissured and the porous ones. The behavior of the system is clearly different according to geological and geomorphological sectors (hills, piedmont and plain).
