Tabular cross-bedding, or planar bedding consists of cross-bedded units that are extensive horizontally relative to the set thickness and that have essentially planar bounding surfaces. [3] Trough cross-bedding, on the other hand, consists of cross-bedded units in which the bounding surfaces are curved, and hence limited in horizontal extent.
These structures are within sedimentary bedding and can help with the interpretation of depositional environment and paleocurrent directions. They are formed when the sediment is deposited. Cross-bedding Cross-bedding is the layering of beds deposited by wind or water inclined at an angle as much as 35° from the horizontal. [1]

A number of cross-bedding patterns are found in sediments, and reflect the currents that deposited them. Subcategories. This category has only the following ...
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
Greta Cross, USA TODAY. Updated December 6, 2024 at 7:08 AM. Police have arrested a woman who they say kidnapped her own children from a Virginia bus stop on Thursday, triggering an Amber Alert.
A cross-section of a delta shows the cross bedding in the direction of stream flow into the still water. The foreset bed is formed when a stream carrying sediment meets still water. When the stream meets the still water, the velocity of the water is decreased enough so that the larger sediment particles can no longer be carried and are ...
It has a long and deep history in South Asia and in the Indian subcontinent,” explains Sanjog Rupakheti, a professor of history at the College of the Holy Cross in Massachusetts and a Nepal native.
