Definition of slickenside in English:
slickenside
noun ˈslɪk(ə)nsʌɪdˈslɪkənˌsaɪd
usually slickensidesGeology A polished and striated rock surface that results from friction along a fault or bedding plane.
Example sentencesExamples
- Where they are exposed, the surfaces of these faults are highly polished with slickenside lineations and the faults also have a mean dip of 45 degrees.
- Some longitudinal faults display a second generation of slickensides due to a dextral reactivation that locally modifies the geometry of the fault network.
- There is limited evidence from slickensides for dip-slip movement along this fault.
- Main normal-throw components are documented both by steps on the fault slickensides and by downthrown offsets of basaltic layers.
- Brittle deformation is evident from a number of fault planes showing quartz slickensides consistently dipping at c.40 deg to the southeast.
Origin
Mid 18th century: from a dialect variant of the adjective slick + side.
