Advances of research on localized deformation in porous rocks

WANG Bao-shan1,LI Juan2,CHEN Yong2(1. Institute of Geophysics, China Seismological Bureau, Beijing 100081, China; 2. China Seismological Bureau, Beijing 100039, China)  
Compaction band is a failure mode that develops in the Brittle\|Ductile transition regime, and the observation of compaction band revises the conventional idea on the orientation of localized deformation. Because of the importance in understanding the movement and deformation of the crust and its potential applications in petroleum industry and material science, research on compaction band has became one of the hotspots in rock physics and geology. In this paper, we elucidate the new progress in localized deformation research on high porosity rocks, and introduce especially the experimental, theoretical and numerical researches on compaction bands. Field observation, experimental results, and numerical simulation all indicate that: as an intriguing failure mode in brittle\|ductile transition regime, compaction band tends to occur and develop in well sorted sandstones.
