| 摘 要： | 作者在辽宁省本溪地区大范围内发现黑云母击象,这在该区尚属首次。黑云母击象以及存在的地质环境表明,在地质演变史上,本溪地区曾存在至少一期影响普遍的快速构造变形—岩浆活动事件,它很可能代表一次古断裂地震活动。

| Abstract: | Percussion figure of biotite developed in the Archaean rocks in Benxi area,is the result of deformation of high strain rate. Generally,the longest parting amongthree sets of partings of percussion figure is parallel to the optic-axial plane of biotite.In most cases, percussion figure of biotite are closely related to the tectonic-magmaticactive zones. The formation of percussion figure of biotite probably re-presented ateast one phase of old fracture earthquake activity in Benxi area. |
