  2. Graded bedding - Wikipedia

    en.wikipedia.org/wiki/Graded_bedding

    Schematic illustrations of two styles of graded bedding: left: normal grading; right: coarse tail grading. In geology, a graded bed is a bed characterized by a systematic change in grain or clast size from bottom to top of the bed. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into ...

  4. Sieve analysis - Wikipedia

    en.wikipedia.org/wiki/Sieve_analysis

    A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...

    Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...

  7. Geotechnical engineering - Wikipedia

    en.wikipedia.org/wiki/Geotechnical_engineering

    It uses the principles of soil mechanics and rock mechanics to solve its engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences. Geotechnical engineering has applications in military engineering, mining engineering, petroleum engineering, coastal engineering, and offshore construction.

  8. Bed (geology) - Wikipedia

    en.wikipedia.org/wiki/Bed_(geology)

    In geology, a bed is a layer of sediment, sedimentary rock, or volcanic rock "bounded above and below by more or less well-defined bedding surfaces". [1] A bedding surface or bedding plane is respectively a curved surface or plane that visibly separates each successive bed (of the same or different lithology) from the preceding or following bed.

  9. Cleavage (geology) - Wikipedia

    en.wikipedia.org/wiki/Cleavage_(geology)

    Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism. [1] The degree of deformation and metamorphism along with rock type determines the kind of cleavage feature that develops.
