General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    Parallel bedded sandstone with large vertical to 'U' shaped burrows (probably Diplocrateron or Rhizocorallum). Parallel bedding defined by thin laminae of carbonaceous material and reddish brown siderite pellets

Depositional Environment Represented:

    Marine shoal/shoreface.

Other environments where rock type is typically found:

    Not found in other environments

General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    massive sandstone with thin vertical burrows (probably Skolithos or Arenicolites)

Depositional Environment Represented:

    Intertidal to shallow subtidal areas of marine shoals

Other environments where rock type is typically found:

    Sandy, shallow marine environments such as tidal deltas, tidal point bars, tidal flats.

General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    bedded sandstone. Lenticular bedded sandstone streaks in mudstone at top.

Depositional Environment Represented:

    Tidal flat

Other environments where rock type is typically found:

    Low to moderate energy areas with variable current velocity such as tidal point bars, marine shoals, splays, lagoons, offshore near fair-weather wave base.

General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    Lenticular and flaser bedding: sandstone and mudstone

Depositional Environment Represented:

    Typical of tidal flats

Other environments where rock type is typically found:

    flaser and lenticular bedding indicate both sand and mud are available and that periods of at least moderate current activity (sand deposition) alternate with periods of quiescence (mud deposition). These conditions are characteristic of subtidal and intertidal areas.

General Environmental Setting:

    Marine and transitional marine to tidal flat

Rock Description:
    Massive sandstone with vertical burrows

Depositional Environment Represented:

    Intertidal to shallow subtidal areas of shoals.

Other environments where rock type is typically found:

    Shoreface environments of moderate wave energy.

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.

General Environmental Setting:

    Non marine: fluvial

Rock Description:
    Breccia-sandstone: mudstone intraclasts in this sample have only been transported a short distance otherwise they would have disintegrated.

Depositional Environment Represented:

    Channel

Other environments where rock type is typically found:

    Intraclasts (rip-up-clasts) are common in channel of every environment.

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
