| 中文摘要:本区的Sr-Nd-Pb同位素演化轨迹清楚。隆起区岩浆岩是元古宙陆壳在下地壳局部重熔或重熔－混染产物。沿海区大面积火山喷发是中生代的地幔上涌所造成的，Sr-Nd-Pb同位素组成普遍有地幔或下地壳混染特征，出现同位素演化轨迹的大转折。 |

| CRUST-MANTLE ISOTOPIC EVOLUTION TRACK ALONG THE MARGIN OF THE PACIFIC IN ZHEJIANG AND FUJIAN PROVINCE |

| Abstract: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. |
