Clay Minerals Vancouver Island University,2012-1-4 · Illite Illite is similar to muscovite and is the most common clay mineral, often composing more than 50 percent of the clay-mineral suite in the deep sea. They are characteristic of weathering in temperate climates or in high altitudes in the tropics, and typically reach the ocean via rivers and wind transport. Relict Fruitful in illite

  • Difference Between Kaolinite and Montmorillonite

    2020-9-4 · The key difference between kaolinite and montmorillonite is that kaolinite consists of one aluminium octahedral sheet and one silica tetrahedral sheet whereas montmorillonite mineral has two silica tetrahedral sheet and an aluminium octahedral sheet per repeating unit.. Kaolinite and montmorillonite are clay minerals. These minerals have their chemical structures as sheets stacked (PDF) Clay and clay mineralogy ResearchGate Find and,montmorillonite would be formed in base-saturated soils with low organic matter content and high pH (>6.7), which is the case in Vertisols.
