Discussion on the Forming Mechanism of Stylolite

缝合线形成机理的探讨

Stylolite structure is widely distributed in deep burial acidic volcanic rocks in the northern Songliao Basin .

松辽盆地北部深层的酸性火山岩中广泛发育缝合线构造。

Highly developed stylolite seams by pressure solution and multi stages of calcite veining are widely distributed in the fault zone .

广泛发育的压溶缝合线与多阶段方解石细脉遍布构造带不同部位。

Secondary dissolution porosity plays the key role of reservoir quality . Solution pore , solution fissure and solution stylolite are the main reservoir spaces .

次生溶蚀孔隙是形成高质量储层的重要组成部分。本区的储集空间丰富多样，溶孔、溶缝和缝合线溶孔等次生溶蚀孔隙是最主要的储集空间。

Three diagenesis types are help to differentiate the middle Caledonian and early Hercynian karst , which are stylolite , dolomitization and dedolomitization .

有三种成岩作用类型有助于区分加里东中期和海西早期岩溶，它们分别是缝合线、与缝合线相关的埋藏白云石化及其相关的去白云石化。

Through an analysis of the basic characteristics of pressure solution of carbonate rocks , the authors present the thickness restoration principle and formula of pressure solution carbonate rock and discuss the organic matter abundance correction method and formula of stylolite .

通过碳酸盐岩压溶作用基本特征的分析，笔者提出了压溶的碳酸盐岩地层厚度恢复的原理和公式，同时还探讨了缝合线有机质丰度的校正方法与公式。
