In those cases, the lateral limits of the sedimentary layer will be marked by an abrupt change in rock type. Often, the sedimentary basin is within rocks that are very different from the sediments that are being deposited. If sufficient sedimentary material is available, it will be deposited up to the limits of the sedimentary basin. The lateral variation in sediment within a stratum is known as sedimentary facies. In its place, the particles that settle from the transporting medium will be finer-grained, and there will be a lateral transition from coarser- to finer-grained material. Often, coarser-grained material can no longer be transported to an area because the transporting medium has insufficient energy to carry it to that location. However, as the amount of material lessens away from the source, the layer of that material will become thinner. As long as sediment is transported to an area, it will eventually be deposited. Layers of sediment do not extend indefinitely rather, the limits can be recognized and are controlled by the amount and type of sediment available and the size and shape of the sedimentary basin.

How to use 3d Block Diagrams To view block diagrams, you will need to use a compatible brower. PRINCIPLE OF ORIGINAL HORIZONTALITY A principle by which layers of sediment are generally deposited in a horizontal or nearly horizontal position. The Principle of Original Horizontality states: Layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous. A principle which states that in any undeformed sequence of sedimentary rocks, each bed is older than the one above and younger than the one below. The principle of lateral continuity states that layers of sediment initially extend laterally in all directions in other words, they are laterally continuous.

The Permian through Jurassic strata of the Colorado Plateau area of southeastern Utah that makes up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park.
