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:
    Horizontal-ripple cross-laminated sandstone with mudstone partings. Only lee side of ripples preserved

Depositional Environment Represented:

    Overbank deposit (levee or splay).

Other environments where rock type is typically found:

    Not found in other environments

General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Horizontal and ripple cross-laminated sandstone with mudstone partings

Depositional Environment Represented:

    Overbank (levee or splay)

Other environments where rock type is typically found:

    Alternating low (mudstone) and moderate energy (sandstone) such as tidal or subtidal facies or facies characterized by periodic flooding (overbank areas).

General Environmental Setting:

    Nonmarine - overbank

Rock Description:
    Convolute (soft-sediment structures) and horizontal bedded sandstone. Note the syn-depositional fault near the base

Depositional Environment Represented:

    Channel of proximal crevasse-splay

Other environments where rock type is typically found:

    Any moderate to high energy facies characterized by rapid deposition.

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:
    Massive siltstone. The absence of bedding may be the result of rapid deposition, bioturbation, rooting or rapid de-watering. Alternatively bedding may be present but not visible to the unaided eye

Depositional Environment Represented:

    Crevasse-splay, levee or lacustrine.

Other environments where rock type is typically found:

    Not found in other environments
