河北平原第四纪断块扭转运动与地震

TORSIONAL MOVEMENT OF QUARTERNARY FAULT BLOCK AND EARTHQUAKE IN HEBEI PLAIN

  • 摘要: 地壳是成层的。它被不同深度的断裂切割为许多大小不等的地质块体谓之断块。在区域构造应力场中断块可以某种特定的方式运动。断块运动不仅有利于某些矿产的运移富集1),同时对块内地震的孕育和活动有控制作用。本文根据判定地壳升降运动的主要标志──沉积厚度及岩相探讨河北平原第四纪断块扭转运动与地震的关系。

     

    Abstract: The crust is layered,and dissected into many geological blocks of different sizes called fault blocks by faults in different depth.Fault blocks can move in a certain part-icular way in regional structural stress fields.The movement of fault blocks not only are advantageous to the movement and gathering of mineral products, but also can co-ntrol the intraplate earthquake preparation and activity.In this paper, according to the principal marks-deposit depth and lithofacies-for determining crustal rising and descending movements, the relationship between the torsional movement of quarternary fault blocks and earthquakes in Hebei plain is discussed.
