Fossiliferous Shale. Group- Clastic Texture- Very fine grained with fossils Composition- too fine to identify Environment - lacustrine (lake) Rock Gypsum. Group- ChemicalIn zone LMX-3, the mixed shale shows relatively well-developed lamination, with generally light-colored detrital silt laminations interbedded with dark laminations composed of clay, organic matter, pyrite and some detrital grains. In addition, graptolites are abundant along the shale bedding planes, forming fossiliferous layers (Fig. 14 a

An overlying fossiliferous shale with a restricted fauna and shell lag is interpreted as having been formed in a lagoon with restricted circulation. The …The fossiliferous shale overlies thin-bedded, laminated dolomites and dolomitic limestone, which are about 20 m thick. The succession above the fossiliferous shale unit is dominated by alternating dolomite, oolitic dolostone, and reddish siltstone with ripple marks, containing microbial mounds, gypsum breccia, and halite pseudocrystals. ….

Limestone is dark gray to very light gray, yellowish gray, very thin bedded to massive bedded, and fossiliferous; locally the thin bedds are argillaceous other beds are oolitic and a few contain chert. Shale is medium gray, greenish gray, pale red, dark redish brown, black, sandy fossiliferous and calcareous; black shale in part is fissile.Perry Farm shale member. The middle member of the Lenapah formation includes calcareous fossiliferous shale above the Norfleet limestone and below the Idenbro limestone (Jewett, 1941, p. 339). It is characterized by irregular limestone nodules in gray shale. At its upper boundary the Perry Farm shale grades into the overlying Idenbro limestone.Introduction to the Depositional Environments of the Trenton Group. Given the long period of geologic research on the Trenton Limestones, it is no surprise that extensive studies have been made of the the stratigraphy and sedimentology of these fossiliferous limestones. Nearly 150 years were dedicated to the study of the stratigraphy and ...

Sedimentary rocks are rocks composed of sediment. Sediment is deposited in a number of environments of deposition, by both moving air and moving water. Sedimentary rock identification is primarily based on composition. Texture will still be used but in a different sense than for igneous rocks.16‏/07‏/2023 ...
