Abstract Identifying the mechanism and formation time of a mud volcano is one of the most debatable issues concerning the geological phenomenon of mud volcanism. As of now, the use of 3D seismic data is a unique technique that allows documenting the main formation stages of mud volcanism and revealing the connection of this process with the formation of hydrocarbon deposits in the South Caspian Basin (SCB). It is shown that the formation of mud volcanoes began after the accumulation of the Maikop (Oligocene–Lower Miocene) series stratum and continued in parallel with the deposition of sediments. As the thickness of the sedimentary cover increased, mud volcanoes periodically became active. A paragenetic relationship may perhaps exist between the formation of mud volcanoes and the formation of petroleum hydrocarbons.

从2D和3D地震资料看南里海盆地泥火山的形成机制

摘要 确定泥火山的形成机制和形成时间是泥火山地质现象中最具争议的问题之一。到目前为止，使用 3D 地震数据是一种独特的技术，它可以记录泥浆火山作用的主要形成阶段，并揭示这一过程与南里海盆地 (SCB) 碳氢化合物沉积物的形成之间的联系。结果表明，泥火山的形成开始于迈科普（渐新世-下中新世）系列地层的堆积之后，并与沉积物的沉积并行继续。随着沉积盖层厚度的增加，泥火山周期性地活跃起来。泥火山的形成和石油烃的形成之间可能存在共生关系。
