| CRUST-MANTLE ISOTOPIC EVOLUTION TRACK ALONG THE MARGIN OF THE PACIFIC IN ZHEJIANG AND FUJIAN PROVINCE |
| The Sr-Nd-Pb isotope evolution in the investigated area appear in a clear track.The isotopic char-acteristics of magmatic rocks in the uplifted area are derived from partial melting or remelting contami-nation of Proterozoic continents in the lower crust.Large guantity of the Mesozoic volcanic eruption in the area nearer to the pacific was caused by the mantle upwelling.The Sr-Nd-Pb isotopic compeition of the volcanic rocks has a characteristics of crust-mantle hybridization,that can be revealed from the ewist of isotopic evolution track. |
