构造序次(tectonic generation,structural generation)简称序次,曾称为构造世代、构造世序,是反映地质构造内在联系的一个重要概念,由李四光提出,表示在同一场地壳运动中,岩块或地块遭受于同一时期、同一动力作用方式持续作用下,所形成的不同性质和排列方位的各项结构面先后出现的程序。是由于边界条件的局部改变,各项构造形迹依挨次控制关系而出现。
地质异常是在结构、构造或成因序次上与周围环境有着明显差异的地质体或地质体组合。
A geological anomaly is a geological body or complex of bodies with obvious different compositions, structures or orders of genesis as compared with the surrounding circumstances.
