General Environmental Setting:

    Marine shoreface - beach

Rock Description:
    Cross-bedded sandstone

Depositional Environment Represented:

    Upper shoreface or distributary channel

Other environments where rock type is typically found:

    Moderate to high current velocity areas such as marine shoals, fluvial and tidal point bars, channel bottoms, distributary mouth bars, tidal inlets, tidal deltas and shelf sand ridges.

General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    Ripple cross-bedded and convolute-bedded sandstone interbedded with mudstone

Depositional Environment Represented:

    Tidal flat to shallow subtidal

Other environments where rock type is typically found:

    Areas of alternating high (sand deposition) and low energy (mud deposition) such as splays or some subtidal areas influenced by storms.

General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    Parallel bedded sandstone and mudstone. Note flame structures near base and load casts near top of core

Depositional Environment Represented:

    Shallow subtidal to intertidal

Other environments where rock type is typically found:

    Load casts and flame structures form as a result of differential compaction of wet sediments.
