通过SEM观测,在三例韧脆性剪切滑动带的断层岩(美国加利福尼亚州Cajon Pass深钻中的变余糜棱岩,陕北陕参1井和黄海NH钻中的流变岩)中,发现了韧脆性剪切带断层岩所特有的微米纳米级超微磨粒结构.从微粒组构学、粒滑流变学、叶理岩相学和微观动力学(包括动热变质作用、流体渗散作用和颗粒自旋作用)等几个方面,拟对磨粒结构蕴藏的丰富地质信息进行扼要简述,从而展示这一新领域探讨的问题和前景. Through the SEM observation, in three cases of fault rocks with ductile-brittle shear banding (metamorphic rocks in Deep Cajon Pass, California, USA, rheological rocks in Shaan-Shen-1 well and NH-Yellow drill in Yellow Sea) The microstructure of micrometer-sized nanoscale ultrafine abrasive grains, which is unique to the ductile-brittle shear zone fault rocks, has been found. From the aspects of particle structure, slipstream rheology, phylloy facies and microdynamics (including dynamic thermal metamorphism, Role and particle spin) and several other aspects, the abrasive structure of the rich geological information to be outlined in brief, to demonstrate this new area to explore the issues and prospects.
