Silicalites, predominated by pelitic silicalite, occur in collisional zones and back-arc basins. In the collisional zones, they occur as rock sheet as an important part ofophiolitic mé lange, belonging to ophiolitic mélange type silicalite. In the back-arc or interarc basin, they occur as pelitic silicalite intercalation varying in thickness, characteristic of "silica merl",and belonging to abyssal back-arc basin type or carbonate type silicalite. In the magmatic arc, they occur as intercalation related to volcanic hydrotherm or volcalic exhalation, belonging to volcanic arc type silicalite.
