Valdés Galicia Ciencias de la Tierra Mars stresses deformations wrinkle ridges thermal evolution This work tries to establish the possible relationship among cortical stresses evidenced by faults mapped in the surface andthermal evolution on Mars. To achieve it, we made an initial classification of the tectonic-structural systems that appear in surface,which were detected by diverse missions from orbit. This classification was based on the association of the tectonic-structuralfeatures with specific geologic features, which allows to divide them in four groups: I) Grabens and normal faults parallel andradially associated to the Tharsis volcanic bulge. II) Tectonic systems associated to the volcanoes that crown the Tharsis bulge, tothe volcanic mons of Elysium and the surroundings of the Isidis, Argyre and Hellas impact basins. III) Wrinkle ridges that extendfor almost the entire planet. IV) A series of secondary ridges associated to the crustal dichotomy. Later we suggest a classificationbased on the surface extension and on the possible geologic processes that could have originated the different tectonic structures.This last classification allows to associate stresses to specific processes and it contemplates three groups of deformations: local,regional and global deformations. Finally the possible causes of the stresses are suggested, which include: global stresses due toexpansion or thermal contraction, regional or local stresses due to thermal anomalies in the mantle and to lithospheric loads,stresses due to impacts, among others. This allowed to suggest a possible thermal evolution that outlines an initial heating foraccretion, followed by an abrupt cooling in a very short period of time and a later secular cooling, which remains in the presenttime. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843218 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.43 |
