sty·lo·lite

S0830600 (stī′lə-līt′)n. A secondary structure found along contacting surfaces of adjacent calcareous rock layers, the contact zone appearing in cross section as a series of jagged interlocking up-and-down projections that resemble a suture or the tracing of a stylus.
[Greek stūlos, pillar; see stylite + -lite.]

Stylolite


stylolite

[′stī·lə‚līt] (geology) An irregular surface, generally parallel to a bedding plane, in which small toothlike projections on one side of the surface fit into cavities of complementary shape on the other surface; interpreted to result diagenetically by pressure solution.

Stylolite

 

a 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.
