Bazhenov Ciencias de la Tierra tensional fracture Experimental tectonics Nucleation and development of microrelief and fragmentation of coating under tensile extension of polymer films coatedwith a thin rigid layer is studied, and the mechanisms responsible for the development of both types of structures are discussed.The development of regular folding is controlled by compression-induced buckling instabilities in a rigid coating on a compliantsupport. Parallel cracks are due to features of mechanical stress transfer from a soft substratum to a rigid coating via an interface.Micro-relief is similar to relief of the oceanic floor in the vicinity of mid-oceanic ridges. We suggest that the young oceanic crustand the upper mantle may behave as a solid coating on a soft basement system. 2001 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56840202 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.40 |
