cross-bedding

[¦krȯs ′bed·iŋ]
(geology)
The condition of having laminae lying transverse to the main stratification planes of the strata; occurs only in granular sediments. Also known as cross-lamination; cross-stratification.

cross-bedding

In sedimentary rocks, inclined laminations or bedding which lends textural and color pattern to building stone of such material.

No matter what mechanism one might invent for transporting sediment during the global Flood, including Austin's recently proposed submarine liquefied sediment gravity currents, (79) it should be realized that the absurdly high sediment transport rates needed to deposit a regional-scale layer such as the Coconino Sandstone in a matter of days will always be at odds with the slow water velocities and gradual sediment transport rates needed to form even the most basic cross-bedding structures.
Schlieren exhibit layering similar to cross-bedding and preserve ripple marks along their base.
The predominant sedimentary structure in this subunit of the section is tabular-planar cross-bedding (up to 1 m thick), as well as trough cross-bedding.
Cross-bedding is a feature in sedimentary rock in which strata include internal sets of layers that are inclined at an angle to the original horizontal bedding of the rock unit as a whole (Fig.
