Degradación de terrazas sobre substrato evaporítico y relieve invertido de paleodolinas
Tenace degradation on evaporíte substratum and paleodolines inverted relief
PublisherSociedad Geológica de España
AbstractThe evolution of the fluvial and alluvial Quaternary deposits in the surroundings of Zaragoza is controlled by the dissolution of the Miocene substratum . Karstification of Miocene evaporites conditioned changes in thickness and sedimentary facies of such deposits , and, in addition, the land forms resulting from its degradation. Recently created new road and railway cuts expose, not only unconformable Quaternary remains, but also disorganized materials in ancient dolines. These increase in thickness may be the reason for the preservation of Quaternary remains in the hills, forming "inverted reliefs"
