释义 | stylolitesty·lo·liteS0830600 (stī′lə-līt′)stylolite(ˈstaɪləˌlaɪt)Stylolitestylolite[′stī·lə‚līt]Stylolitea type of feature encountered in sedimentary rocks wherein spinous or columnar projections on the surface of one layer fit into cavities of complementary shape on a second layer. In cross section, the stylolite surface suggests gear teeth in mesh. The columns can reach 1 m in length, and their sides are covered with striations parallel to the longitudinal axis. A clayey substance forms along the plane of the seam. Stylolites are often converted to sutures—zigzag seams with conical teeth. Stylolites occur in limestones and, more rarely, dolomites, coal, argillites, quartzites, gypsum, and other sedimentary formations. REFERENCESKholodov, V.
