Jul 10, 2011 · The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments. Continental. Transitional.
shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles.Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth.. Shales are often found with layers of sandstone or limestone.They typically form in environments where muds, silts, and other sediments were deposited ...As shown in figure 109, solution openings in limestone under the Appalachian plateaus are developed primarily along the bases of the escarpments and do not extend far under the shale and sandstone. Water-quality data, however, indicate that circulation has been sufficient to allow freshwater to displace saltwater from the limestone in most places.laboratory data presented in Figs. 1–3 for sandstone, shale, and limestone and dolomite, respectively. Despite the considerable scatter in the data, for each rock type, there is a marked decrease in strength with Δt and ϕ, Fig. 1. Comparison between different empirical equations listed inOver time, compressed sandstone and limestone become shale. Shale typically occurs in a broadsheet, several meters thick. Depending on the geography, lenticular formations may also form. Sometimes animal tracks, fossils, or even imprints of raindrops are preserved in shale layers. Composition and Properties Kristin Piljay / Getty ImagesAt a given location, the changes from one rock type to another indicate the moving positions of the shoreline. During an ice age these cycles can repeat hundreds of times, and gave rise to the great coal swamps of the Carboniferous. These formed in coastal swamps, but above and below will be offshore sandstone, shale, and limestone.
Fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone.

There are many formations and PSI that PDC bits work well in such as shale, sandstone, limestone, sand, and clay. The benefit to PDC bits is they also can work well in both soft and hard formations. Whereas, most rock bits are only designed for rock and the rate of penetration dramatically drops when in softer formations.The Bright Angel Shale consists of locally fossiliferous, green and red-brown, micaceous, fissile shale (mudstone) and siltstone with local, thicker beds of brown to tan sandstone and limestone. It ranges in thickness from 57 to 450 feet (17 to 137 m). Typically, its thin-bedded shales and sandstones are interbedded in cm-scale cycles. quartzose sandstone, and coarse- to fine-grained, lithic-feldspathic-quartzose gray-wacke with an argillaceous-ferruginous-calcareous matrix.

Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are named dolomite rock.
Lower member--consists of two parts: poorly resis Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.
