火成岩分为侵入岩喷发岩等,如何依据地震数据判别火成岩是侵入岩还是喷发岩形成的,对于研究火成岩的成藏具有十分重要的意义。在正演模拟的基础上,通过对火成岩区实际地震资料的频率、振幅等地震叠前属性特征以及能量衰减规律进行分析,能够识别出火成岩是侵入岩还是喷发岩?这对于火成岩的地质成像和研究火成岩的成藏具有一定的意义。
The igneous rocks are divided into intrusive rocks and eruptive rocks. How to judge whether the igneous rocks are intrusive rocks or eruption rocks according to the seismic data is of great significance for studying the accumulation of igneous rocks. On the basis of forward modeling, by analyzing the characteristics of prestack seismic attributes such as frequency and amplitude of the actual seismic data in igneous rock region and the law of energy decay, we can identify whether the igneous rock is an intrusive rock or an eruptive rock. It is of significance to study the accumulation of igneous rocks.
