Features and evolution of slip structures in badlands areas (SE Spain)

摘要: Abstract Slips are little known mud-coated structures several centimeters thick, produced by gravity-driven flows on free vertical surfaces. We have differentiated a sequence formed three main morphologies: mud drips, slips and pseudo-stalactites. This study, located in the badlands of Guadix Baza basins (SE Spain), suggests that formation muddy morphologies subvertical walls is determined physico-chemical characteristics colloidal suspensions (slurries) related to rainy periods does not indicate any substrate decay. Multiple braided microchannels, internally structured like irregular book pages, commonly found, each mudflows during episodes. These constitute temporary sink fine erosive materials. They consist scarcely sorted mixtures heterogeneous matter detrital-cohesive nature, with low clay contents, which inherit features parent The current semiarid environmental conditions appear favor conservation rather than development. differences observed can be different geomorphological evolution two and, lesser extent, properties slurries fed slips.
