Resumen
The decay caused by the repeated thermal oscillations due to insolation-shadow cycles has been discussed during more than a century both in terms of its relative effectiveness and extent of the damage caused. Previous studies in this area have looked for an explanation of damage features caused in temporal and spatial scales that can only be explained by insolation decay. Current research addresses the study of possible insolation decay at a scale where the potential effectiveness of this phenomenon increases. Results show that decay generated merely by repeated thermal oscillations must be considered at a more detailed scale, which affects mainly at a granular scale. Temporal scale must also be modified, as insolation appears only to produce decay by itself at a very slow rate and from effects such as fatigue caused mainly by short-term temperature fluctuations. In addition, the effectiveness of insolation cycles must be taken into account further than the phenomenon itself and through the influence that internal thermal gradients may have on other decay agents.
