The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

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.
