【摘要】 贵州雷山一带的震积岩见于清水江组中、上部,发育液化变形层理、微断层、微褶皱、震裂岩、震塌岩及砂枕构造等。根据野外实际观察,分别建立了变余沉凝灰岩、凝灰质板岩和变余凝灰质砂岩中完整的地震扰动序列。更多还原

【Abstract】 A rock series in and with seismic genesis and features, such as liquefied deformational beddings, micro_folds, micro_faults, shattering rocks, seismic collapse rocks and sandy pillows, has been recognized in the upper_mid Qingshuijiang Formation of Late Proterozoic in Leishan county. Two complete disturbed successions in seismic genesis are established, i.e. in descending order, the first lies in the blastotuffite and tuffaceous slate, including: a. liquefied deformational bed, b. the upper micro_fold and micro_fault zone, c. shattering rock, seismic collapse rock, and e. lower micro_fold and micro_fault zone; the second occurs in blastotuffstone, including: a. liquefied silty deformational bed and micro_folds in blastoclaystone, blastotuff and silty veinlets, b. shattering rock and blasto_argillaceous and _tuffaceous deformational bed (micro_fold), c. polygonal beds and sandy pillows. In addition, deformed bedding can be seen commonly in blastotuffstone.更多还原
