Though lacking well considered theory about application of lead isotopes to geochemical exploration and evaluation of deposits, we have succeeded in prospecting Au, Cu, Pb, Zn and U deposits with the method of lead isotope targeting and geochemical exploration of lead isotopes along the field section systems.

The target chamber and the rotating target wheel for synthesis of superheavy elements at Radioactive Ion Beam Line of Lanzhou(RIBLL) are described in the paper.
