Base isolation systems are among the most successful and widely applied methods of mitigating structural vibration and damage during seismic events. These systems have been installed in numerous full-scale structures all around. There are three principal types of base isolators: Lead Rubber Bearing (LRB), High Damping Rubber Bearing (HDRB), and Fri...

Total number of nineteen mafic extrusive rock samples is subjected to the detailed optical examination. Based on definition of mineral composition, structure, texture, type and intensity of alteration processes, and taking into consideration the recent classification schemes, different lithotypes are defined. The most frequent are spilites distingu...
