Sedimentary environments are an important part of paleogeography and sedimentology, and there is a long history of using geochemical and mineralogical methods to analyze palaeoenvironmental problems using sedimentary rocks as a research vehicle. By summarizing the important results of previous work on tracing the palaeoenvironment using the composition and distribution characteristics of the macronutrients and trace elements as well as the characteristics of mineral composition, we aim to sort o...

Mineralogy, chemistry, and plasticity of the raw clay materials, outcropping in different Tunisian domains were studied. These clays constitute the only mineral resource of the ceramic industries in Tunisia, and are exploitable at eight quarries. Powder X-ray diffraction analysis revealed that illite and kaolinite are the major mineral phases. However, other clay minerals, such as illite/ smectite mixed-layer, and chlorite are also present. The associated minerals detected in powdered materials ...
