General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Intraformational conglomerate (breccia). The core is composed of rip-up-clasts of siltstone

Depositional Environment Represented:

    Crevasse-splay

Other environments where rock type is typically found:

    Not found in other environments

General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Rippled siltstone and sandstone with local rooting. Note the siliceous concretions at the base

Depositional Environment Represented:

    Levee or crevasse-splay

Other environments where rock type is typically found:

    Not found in other environments

General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Lenticular bedded siltstone and mudstone

Depositional Environment Represented:

    Overbank (lake, distal splay, levee)

Other environments where rock type is typically found:

    Any low energy environment in which there is a periodic influx of coarse sediment (flood or storm events) such as tidal, shallow offshore or lake facies.

General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Horizontal bedded mudstone and cross-bedded sandstone. Base of core is composed of rip-up-clasts. This core has been interpreted as the result of a single flood with currents declining from base to the top.

Depositional Environment Represented:

    Crevasse-splay

Other environments where rock type is typically found:

    Not found in other environments

General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Coal

Depositional Environment Represented:

    Peat-forming wetland (mire: marsh or swamp)

Other environments where rock type is typically found:

    Not found in other environments
