Where the set height is less than 6 centimeters and the cross-stratification layers are only a few millimeters thick, the term cross-lamination is used, rather than cross-bedding. Cross-bed sets occur typically in granular sediments, especially sandstone , and indicate that sediments were deposited as ripples or dunes, which advanced due to a ...

Rocks often contain small-scale structures (smaller than the scale of an individual outcrop). In sedimentary rocks this may include sole markings, ripple marks, mudcracks and cross-bedding. These are recorded as they are generally characteristic of a particular depositional environment and may provide information on paleocurrent directions. [25]
Cross-bedding – the axis of a trough cross bed or the down-dip direction of a tabular cross bed point the direction of paleo flow. Current ripple marks – will have the short side of the ripple pointing down stream. Sole markings/flute casts – the short, steep side will point up stream, and the long, tapered side points down stream.
Semax is a medication which is used in Russia and Eastern Europe for the treatment of a broad range of conditions like brain trauma but predominantly for its claimed nootropic, neuroprotective, and neurorestorative effects.
A number of cross-bedding patterns are found in sediments, and reflect the currents that deposited them. Subcategories This category has only the following subcategory.
