通过对火山岩岩石特征及岩石化学组成的分析,研究了松辽盆地晚侏罗世火山岩的构造环境,结合大地构造研究的成果,提出了火石岭期火山岩盆地为大陆岛弧火山岩台地上的以火山为边界的弧内盆地。这些火山岩在横剖面上基本上由中央相、火山裙相及远端相组成,在此基础上建立了松辽盆地火山岩的相模式,并进行了含油性评价。
Based on the analysis of volcanic rock characteristics and petrochemistry, the tectonic environment of the Late Jurassic volcanic rocks in the Songliao Basin was studied. Based on the results of the study on tectonics, the volcanic basin of the Flint Ridge Period was proposed to be a volcano Arc within the border basin. These volcanic rocks are basically composed of central facies, volcanic skirt facies and distal facies in the cross-section. On this basis, the phase models of volcanic rocks in the Songliao Basin are established and their oil-bearing properties are evaluated.
