断层

• Active faults or tectonic lines are clear boundaries between a very active region and a quiet region .
  活动断层或构造线是强烈活动已和平静区之间的清晰边界。
• A major vertical fault scarp formed during the earthquake was less than 1000 ft from the spillway .
  地震时形成的一个主要的垂直断层崖，离溢洪道不到1000英尺。
• Mechanical changes and sometimes lithological changes, take place in the rocks on either side of the fault .
  断层两边岩层发生机械力学变化，有时也有岩性变化。
• Sudden rupture and displacement occurs with normal, reverse, strike-slip, or oblique-slip faulting .
  突然破裂和位移伴随正、逆、走向滑动或斜向滑动断层作用而发生。
• Gouge or infilling is the material between two faces of a structural discontinuity such as a fault .
  断层泥或充填物是指一个不连续面（如断层）的两个表面之间的物质。
• Volcanoes and earthquakes have been frequent along a great fault or weakness in the crust along this line .
  沿着这条线上的地壳中大断层或脆弱带火山活动和地震一向很频繁。
• The western tongue has a synclinal bottom configuration, the axis of which plunges at a low angle towards the fault .
  岩体西支具有一向斜底的形状，其轴以低角度向断层倾没。
• It may be gouge of finely comminuted rock material with perhaps large blocks of the harder rocks embedded in it .
  可能是磨碎的岩层物质组成的断层流，并夹杂一些大块坚硬岩石。
• The composition of the rock and the occurrence of natural faults, cracks and weak zones exert a great influence .
  岩石的成份，及天然断层、裂隙和软弱夹层的存在，都有很大影响。
• The initiation and maintenance of faults will depend upon the contemporary system of tectonic stresses in the earth's crust .
  断层的发生和保持取决于地壳的构造应力的同代体系。
