GENERAL GEOLOGY

Detailed explanation-1: -Clay minerals are the most abundant minerals in mudstones, making up over 60% of all mudstones. Other minerals like quartz, feldspar, carbonate minerals, organic compounds (not really minerals), sulfides, and hematite also occur.

Detailed explanation-2: -mudstone, sedimentary rock composed primarily of clay-or silt-sized particles (less than 0.063 mm [0.0025 inch] in diameter); it is not laminated or easily split into thin layers.

Detailed explanation-3: -Mudstone. Mudstone is made up of fine-grained clay particles (<0.05mm) compressed together. Mudstones form where clay has settled out in calm water-in lakes, lagoons, or deep sea. Flaky mudstone is called shale.

Detailed explanation-4: -Mudrock is the commonest sedimentary rock, the two principal types being shale and mudstone. Shale is characterized by its lamination. Mudrock composed of grains of a similar size range and composition that is not laminated is usually referred to as mudstone.
