Abstract

Abstract ––The Aeronian clastic sediments in the Gorny Altai area bear signatures of past seismic effects (paleo-seismites). Sedimentary structures produced by brittle deformation (breccias) span the level of the upper convolutus graptolite zone and the lower sedgwicki zone. They coexist with soft-sediment deformation structures (SSDS), such as turbated and rolled layers, bumpy layer boundaries, etc. At the final deposition stage, the rocks were deformed during seismically-triggered landsliding and were shed into a submarine canyon, with formation of rolls (pseudo-conglomerate).

阿尔泰西部气相海相碎屑沉积物同沉积地震效应特征

摘要阿尔泰高原空纪碎屑沉积物具有过去地震作用(古震积岩)的特征。由脆性变形(角砾岩)形成的沉积构造横跨上卷陀笔石带和下塞奇威基带。它们与软沉积变形结构(SSDS)共存，如扰动和滚动层、凹凸层边界等。在最后的沉积阶段，岩石在地震引发的滑坡中变形，落入海底峡谷，形成卷状(伪砾岩)。

期刊介绍： The journal publishes original reports of theoretical and methodological nature in the fields of geology, geophysics, and geochemistry, which contain data on composition and structure of the Earth''s crust and mantle, describes processes of formation and general regularities of commercial mineral occurrences, investigations on development and application of geological-geophysical methods for their revealing. As to works of regional nature, accelerated publication are available for original papers on a variety of problems of comparative geology taking into account specific character of Siberia, adjacent Asian countries and water areas. The journal will also publish reviews, critical articles, chronicle of the most important scientific events, and advertisements.
