Abstract: The basic concept and method of wave geology and its application in the basin anlysis inHuanghua depression have been briefly explained in this paper.The wqve processes-describes the regular diffusion of stress,point movement and itscondition is time and space.The process is called linear wave if the amplitudes and cycles areconstant in the diffusion process on the contrary,a non-linear wave process occurs.The geological features of the cyclicity and rhythm of metailogenesis and sedimentation are in fact theresults of superposition and interference of a series of non-linear wave processes.Therefore,the objective of wave process study is to find out these regularities.These regular cycle wavescan be decomposed by the sliding window step by step and then cycles,wavelengths,traveltimes,and amplitueds can be calculated.The evolution history since Cenozoic has been analysized in this way.The result of study shows that the evolution of the depression are controlled by four rnain non-linear waves,theyare F,g,n,l,with cycles:T_f=200～220,T_g=60～70,T_n=27～35,T_l=6～10 Ma.seperately.The amplitude of this wave beam are mainly dependent on the changing of waves withgreater cycles,having a exponential or logarithmio,distribution this is a typical characteristics of a rift system.The phase of these waves migrate from south to north in section,and inplane their frequencies become gradually faster from south to north (T_s=30～35,T_n=22.8Ma),which is of important significance for predicting planar vflriations of sealing andreservoir formations.
