The Burr limestone member is composed of two distinct limestone beds and a bed of shale between. The lower limestone is about 4 feet thick, massive, and is somewhat impure at the top and bottom.

The only difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. Both are made of ancient mud. From the point of view of understanding the ancient conditions of sediment deposition, it is more useful to subdivide mud rocks into siltstone and ...

Lithofacies 8: contains terrigenous to shallow-marine deposits, richly fossiliferous sandstone, dark-gray to green shale with thin, sandy to black limestone with a diverse stenohaline fauna. Lithofacies 9:Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals.Some common nonmineral constituent terms are: "tuffaceous," "cherty," "fossiliferous," "crinoidal," "coralline," "clayey (argillaceous)," "silty," "shaly," "sandy (arenaceous)," and "conglomeratic." Minor mineralogy should follow the nonmineral composition and should be restricted to one conspicuous mineral not implied in the root name.Gray-green, glauconitic fossiliferous shale occurs throughout the lower Fort Payne Formation and enclosed (overaid) all of the carbonate buildups (Fig. 1). Krause and Meyer (2004) called this the green (fossiliferous) shale facies and combined it with green shales in the core of the buildups. Knox and Stapor (2003) called shales above the Fort ...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.

Table 5.3a. Rock densities and porosities. being in g/cm and or 0.23 when is in m/s or ft/s, respectively.
