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.]


(Palaeontology) any of the small striated columnar or irregular structures within the strata of some limestones
[C19: from Greek stulos pillar + -lite]

1) Three meters of gray, thick-bedded limestone in which traces of stylolite and dispersed fractures are observed.
The diagentic features of the Formation includecementation, dissolution, micritization, fracturing, stylolite, recrystallization, pyrite mineralization and dolomitization and are explained by meteoric, marine and burial diagenetic history of the rock unit.
These are low amplitude stylolite to stylolitic swarms and/or irregular stylolite solution seams are isolated or swarm-like partings characterized by thin seams often with accumulations of insoluble residues (Logan and Semeniuk 1976).
These planes are usually but not always characterized by the accumulation of relatively insoluble residues or authigenic minerals along them which form the stylolite seam.
The diagenetic fabric recognized in the Formation include compaction, cementation, aragonite to calcite transformation, microbial micritization, neomorphism, pressure dissolution and stylolite formation, mechanical and chemical compactional features as fractured and broken grains, dolomitization, incorporation of iron into calcite and dolomite as late stage diagenetic events and deformation due to tectonism.
Photomicrographes of lime mudstone having calcite vain (Cv), stylolite (Sy), ostracods (Os), sponge spicules (Sd) and pellet (Pe) in lime mudstone microfacies.
The presence of clayey/lime mud matrix, neomorphic spar cement, close packing with sutured contacts, stylolites with iron oxide/ clay are the main porosity reducing factors in the Lower Gorn Formation.
The movement along the plane of fracture is usually demonstrated by presence of some kind of the kinematic indicator (calcite steps, slickenlines, stylolites, etc.
The stone is massive, but the thickness of extracted blocks is limited by stylolites.
