GIBBON BAY SHALE With few exceptions, the fossils obtained from the Gibbon Bay Shale are fragmentary an very poorly preserved; from more than 70 fossiliferous shale chips collected, only about ten specimens are even tentatively identifiable. The fauna is limited to brachiopods, gastropods and bivalves, and includes the following forms:The McAbee fossil beds consist of 30 metres of fossiliferous shale in the Eocene Kamloops Group. The fossils are preserved here as impressions and carbonaceous films. We see gymnosperm (16 species); a variety of conifers (14 species to my knowledge); two species of ginkgo, a large variety of angiosperm (67 species); a variety of insects and ...4.1. Dark Gray Shale Lithofacies (Shd) The Dark Gray Shale Facies covers a smaller portion of the area and is located in the low lands within the study area. It comprises of dark gray to black fissile and fossiliferous shale (Fig. 3). This facies was studied at the Kpoghirikpo, Enohia Itim Ukwu, Ugwu Ati, Iyioka river channel,

The marine limestone member that directly overlies the Excello Shale is called the Hanover Limestone. The Hanover is regionally continuous but locally lenticular. In the deeper part of the basin, the Hanover ranges from fossiliferous shale a few inches (centimeters) thick to limestone averaging around 9.8 in. (25 cm) and rarely exceeding 19.7 in.

Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale.

Fossils are more common in shales than sandstones, because of the higher current activity in sandstones.The Pierre Shale is a geologic formation or series in the Upper Cretaceous which occurs east of the Rocky Mountains from North Dakota to New Mexico. The Pierre Shale was described by Meek and Hayden in 1862 in the Proceedings of the Academy of Sciences (Philadelphia). They described it as a dark-gray shale, fossiliferous, with veins and seams of gypsum, and concretions of iron oxide. The ...In southwestern Wisconsin the Maquoketa is ISO to 250 feet in thickness.

It is fired in a kiln with crushed shale to make cement. Some varieties of limestone perform well in these uses because they are strong, dense rocks with few pore spaces.

It wasn’t always the picturesque valley that can be seen today. It was formed over many millions of years, with the help of oceans, glaciers, and rivers.

Weathering has caused heavy leaching and bleaching in some regions of the Bulldog Shale, including those around Coober Pedy, so that the rocks are white or multicolored. These horizons contain rich opal deposits.
