    Sep 03, 2015 · Hydrolysis: It is a chemical process in which water gets dissociated into H + and OH – ions. The hydrogen cations replace the metallic ions such as calcium, sodium and potassium in rock minerals and soils are formed with a new chemical decomposition. Chemical decomposition of rocks results in formation of clay minerals.

    Geologists don't agree on the exact processes involved in the formation of geodes. Given that geodes form in both volcanic and sedimentary rocks under very different conditions, the subject is a complex one. But the most common theory is that geodes form inside already existing hollows within the rock.
