Definition of lithify in English:



  • Transform (a sediment or other material) into stone.

    • ‘Another strong argument against the mammoth death-in-the-Flood hypothesis is that the Beringian animals are buried in unconsolidated surficial sediments overlying lithified sedimentary rocks.’
    • ‘This sediment was locally lithified to form thin hard grounds, presumably at times of non-sedimentation or significantly reduced sedimentation.’
    • ‘Stratification may be deformed penecontemporaneously by various agencies, before the rock is lithified.’
    • ‘The three-dimensional preservation of pellets and fossil remains in the limestones suggests that the carbonate muds were rapidly lithified, and that the limestones record minimal time averaging.’
    • ‘Low-strain deformation of many natural rocks, both unlithified sediments and lithified sedimentary rocks, occurs by strain localization in dilatant joints or in shear bands that can dilate or compact.’


Late 19th century: from Greek lithos stone + -fy.
