补充资料：节理
| 节理 joint 岩石中的裂隙，其两侧岩石没有明显的位移。地壳上部岩石中最广泛发育的一种断裂构造。通常，受风化作用后易于识别，在石灰岩地区，节理和水溶作用形成喀斯特。
节理按成因可分为：①原生节理。成岩过程中形成。如沉积岩中因缩水而造成的泥裂或火成岩冷却收缩而成的柱状节理。②构造节理。由构造变形而成。③非构造节理。由外动力作用形成，如风化作用、山崩或地滑等引起的节理，常局限于地表浅处。节理按形成的力学机制可分为：①剪节理。由剪裂作用形成。节理面平直，延伸较长，两壁常闭合，沿节理面或可见两侧岩块有微小的错开，节理面上可有擦痕 。②张节理。由张裂作用形成。节理面常粗糙不平，延伸较短，常曲折，多分叉，两壁可轻微张开或被结晶物质充填而成脉。构造节理常有规律地成群出现。一群产状一致且力学性质相同的节理构成节理组。在统一应力场中形成的两组以上的节理构成节理系。 与褶皱或断层伴生的节理，常有规律分布于大尺度地质构造的不同部位，反映了各部分的应变状态。在地壳中，节理常作为矿液的流动通道和停积场所，直接控制着脉状金属矿床的分布。节理也是石油、天然气和地下水的运移通道和储聚场所。节理过多发育会影响到水的渗漏和岩体的不稳定，给水库和大坝或大型建筑带来隐患。 |
