| 摘 要： | 为深入研究碳酸盐中缝合线的形成条件及其地质意义,本文以方斗山矿区和洞沟矿区碳酸岩地层中常见的缝合线构造为例,结合前人的研究成果,对缝合线构造进行了分析研究,总结了缝合线形成过程中的主控因素,认为缝合线的形成是由于不均匀介质面上的(如岩层面或层理面)应力变化的结果;并对缝合线的地质意义进行了探讨。

| Abstract: | Stylolite, as a common pressure solution structure, develops extensively in carbonate, which is of great significance in geological structure. Based on field observation and indoor analysis about the stylolites in Fangdoushan and Donggou minging area of Chongqing City, this paper summaried main control factors in the process of becoming stylolites. It is considered that the stylolites were formed due to variation of stress on the surface of inhomogeneous medium. And the geological applications of stylolites were discussed. |
