👉 The term "chlorosilicate" is often used to describe minerals that contain silicon (Si) and chloride (Cl) ions. These minerals are commonly found in the Earth's crust and can be formed through a variety of processes, including weathering, erosion, and alteration. Chlorosilicates can range from simple silicate minerals such as quartz or feldspar, to more complex ones like calcite, which contains silicon dioxide (SiO2) and calcium carbonate (CaCO3
