EXPERIMENTAL MODELS USING DRY ICE AS ACTIVE AGENT IN DIFFERENT GEOLOGICAL PROCESSES FOR THE SURFACE OF THE PLANET MARS

The experimental models are one of the tools that can be used when approaching the verification of a hypothesis, in the case of planetary sciences the concept of planetary analogue is often used due to the impossibility of carrying out field verification work ; Today in the planet Mars some processes are presented as the activity of storms that is responsible for the formation of some sedimentary deposits (ondulitas, dunes and draa's) and the formation of two distinctive geoforms such as the RSL (Recurrent slope Lineae) and the Gullies over which there is still a wide controversy about the processes that give rise to them; In the present work is sought through the development of an experimental model to test a combination of some of the hypotheses to explain the origin to the last of the mentioned geoforms that can be synthesized as "Generation of gullies from the fluidization of CO2 produced by Sublimation of the dry ice in the form of frost or in the subsoil "(Hoffman, 2002, Ishii and Sasaki, 2004, Hugenholtz, 2008, Cedillo-Flores. et al., 2008, Diniega et al., 2010, Dundas et al. Al., 2010; Pilorget and Forget 2015).

By means of the construction of a simple assembly where different granulometries, temperatures, base geoforms and dry ice are used, to observe the occurrence of these processes we work with techniques of video analysis of high speed and decomposition frame by frame in addition to the generation and analysis Of photogrammetric models with which the movement of the particles produced by the sublimation of dry ice is analyzed, in addition to calculating the displaced volumes.
