地球脉动的概念是指地球在其历史中曾发生膨胀和收缩的周期性变化。其根据是构造变动、岩浆活动、地磁极倒转以及海平面升降等方面，在地球的膨胀和收缩期，均有各种表现。构造海平面升降在地球收缩期形成海退，在膨胀期形成海侵。在一个地球脉动旋回的不同时期，地表、海平面和洋底之间的相互关系均有变化，因而形成“层序”的沉积记录。地磁场的强度和地磁极倒转频率在显生宙有明显变化，有高峰期和平静期。这种频率变化与构造变动和岩浆活动都有对应关系，特别是４Ｍａ为准周期的地磁极倒转频率与海底扩张、洋壳形成速率之间具有良好的对应关系。地球脉动旋回可以分为不同的级次，构成级别体系：超级旋回约１Ｇａ，巨旋回２５０～３００Ｍａ，一级旋回５０～１５０Ｍａ，二级旋回５～５０Ｍａ，三级旋回１～５Ｍａ，均可与构造旋回相对应，更高的级次对构造不形成影响。三级及更长的脉动旋回可能受深部过程的控制。中、新生代以来，地球脉动是在地球适度膨胀的背景下进行的。
The concept of the Earth’s pulsation refers to the cyclical changes in the Earth’s expansion and contraction that have taken place in its history. Based on structural changes, magmatic activity, reversal of geomagnetic poles, and sea-level rise and fall, there are various manifestations in the expansion and contraction of the Earth. Tectonic sea level rise and fall in the Earth’s systolic formation of regression, the formation of transgression during the expansion. During different periods of a pulsating cycle of the Earth, the correlation between the surface, sea level and ocean floor has changed, resulting in the “sequence” sedimentary record. The intensity of the geomagnetic field and the frequency of inversion of the geomagnetic poles have obvious changes in the Phanerozoic, with a peak and a quiet period. This frequency change has a corresponding relationship with tectonic movements and magmatism. Especially the 4Ma quasi-period geomagnetic pole reversal frequency has a good correspondence with seafloor expansion and oceanic crust formation rate. Earth’s pulsar cycle can be divided into different levels, constitute the level system: super-cycle about 1Ga, giant cycle 250 ~ 300Ma, a cycle of 50 ~ 150Ma, secondary cycle 5 ~ 50Ma, tertiary cycle 1 ~ 5Ma, both with Corresponding to the tectonic cycles, the higher levels have no effect on the tectonics. Third and longer pulse cycles may be controlled by deep processes. Since Cenozoic, the earth’s pulsation has been carried out under the moderate expansion of the earth.
