图7 西阿尔卑斯Monviso蛇绿岩带硬柱石榴辉岩中石榴石的锰与镁成分环带图 石榴石生长被分为2期, 第一期表现为富Mn石榴石的生长和随后的破裂, 第二期为边部富Mg石榴石的生长对核部的愈合, 暗示了古地震的存在 [ 39 ]
Fig. 7 Mn and Mg content chemical maps of garnet from lawsonite eclogites in Monviso ophiolite, Western Alps The garnet shows presence of two main garnet generations: first one exhibits Mn-rich growth, and second is characterized by Mg-rich overgrowth and healed fossilized fracture networks which imply fossil earthquakes [ 39 ]
