底质不连续面类型、成因及遗迹学特征

底质不连续面是沉积作用中断时所形成的一种地层界面。根据底质的粘结程度可将底质不连续面划分为两大类：固底不连续面和硬底不连续面。固底不连续面中的简单停积面依靠沉积序列的变化来识别，界面上、下的生物地层带是连续的；而复成停积面上、下的生物地层带不连续。在硬底不连续面中，硬底的上、下地层属于同一个沉积体系，而继承性岩底的上、下地层则属于不同的沉积体系，其间发生过重大的沉积间断。根据底质控制的Glossifungites遗迹相和Trypanites遗迹相可以有效地识别各类不连续面并解释其成因。三种类型的不连续面具有层序地层学意义：①侵蚀性不连续面，包括低水位侵蚀面（LSE）和海进侵蚀面（TSE）；②无沉积间断面；③沉积性不连续面（凝缩段）。     

Numerical simulations of deformation and movement of blocks within North China in response to 1976 Tangshan earthquake

Using methods of discontinuous deformation analysis and finite element (DDA+FEM), this paper simulates dynamic processes of the Tangshan earthquake of 1976, which occurred in the northern North China where its internal blocks apparently interacted. Studies focus upon both the movement and deformation of the blocks, in particular, the Ordos block, and variations of stress states on the boundary faults. The Tangshan earthquake was composed of three events: slipping motions of NNE-striking major fault, NE-striking fault near the northeastern end of the NNE-striking fault, and NW-striking fault on the southeastern side of the NNE-striking fault. Compared with previous studies, our model yields a result that is more agreeable with the configuration of aftershock distributions. A number of data are presented, such as the principle stress field during the earthquake, contours of the maximum shear stress, the strike-slip deformation between blocks near the earthquake focus, time-dependent variations of slips of earthquake-triggered faulting, the maximum slip distance, and stress drops. These results are in accord with the earthquake source mechanism, basic parameters from earthquake wave study, macro-isoseismic line, observed horizontal displacement vectors, etc. The Tangshan earthquake exerted different influences on the adjacent blocks and boundary faults between them, thus resulting in differential movement and deformation. The Ordos block seems to have experienced the small-scale counterclockwise rotation and deformation, but its northeast part, bounded on the east by the Taihangshan and on the north by the Yanshan and Yinshan belts, underwent relatively stronger deformation. The Tangshan earthquake also changed the stress state of boundary faults of the North China, leading to an increase in shear stress and a decrease in normal stress in the NW-trending Zhangjiakou-Penglai fault through Tangshan City and the northern border faults of the Ordos block, and therefore raises the potential risk of earthquake occurrence. This result is supported by the facts that a series of Ms ≥ 6 earthquakes took place at the northern margin of the Ordos block after the Tangshan earthquake.
