| 摘 要： | INTRODUCTIONBecause of the inhomogeneity of material composition andtexture in the earth lithosphere,on the margins of differentearth blocks often exists the change of geochemicalcharacteristic values and geophysical gradients. The Pb-isotopetopological diagram which divides different Pb-isotopeprovinces within Chinese continent shows (Zhu,1995) thatsome margins of the Proterozoic basement or boundaries ofancient plates are presented as geochemical steep-dippingzones. The Pb-isotopic co…
