Shale environment.

The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.1.

Black shale results from the presence of greater than one percent carbonaceous material and indicates a reducing environment. Pale blue to blue-green shales typically are rich in carbonate minerals. Clays are the major constituent of shales and other mudrocks. The clay minerals represented are largely kaolinite, montmorillonite and illite.

Normally, this is the only opportunity to “touch” the rocks, insofar as in the real environment they are buried in the ground, sometimes as deep as 3 to 4 km. Paleozoic shale outcrops are seldom seen in Poland, they occur only in the Świętokrzyskie (Holy Cross) Mountains and the Sudetes.

claystone, hardened clay.Some geologists further restrict the term to a sedimentary rock that is composed primarily of clay-sized particles (less than 1 / 256 millimetre in diameter) and is not laminated or easily split into thin layers; such rocks that show cleavage roughly parallel to the bedding plane often are classed as clay shales. Claystones that are …Since shale gas resources in China are mainly distributed in the densely populated areas of Sichuan Basin in central China, the release of shale gas wastewater (SGW) to the environment may induce ecological effects and human risks to the local populations, which could also have important implications for the horizontal hydraulic fracturing and ...earth, shale, sandstone or limestone (Staub and Cohen, 1970).
