| 中文摘要:根据一些热液矿床和赋矿岩浆岩的同位素年龄资料，结合矿床地质研究表明，其成岩成矿时差序列为钨铍铌钽-铜铅锌-金银-萤石依次增大。该序列与成矿元素的S0298/di值递增序列一致，也与矿床的成矿温度从高到低、深度由深至浅、成矿流体来源以岩浆热液到大气降水为主的成矿特征一致。并且随着成岩成矿时差增大，含矿构造由较密集分布的节理或裂隙转变为非常稀疏分布的断裂或断层。 |

| Abstract:Based on isotopic ages of some hydrothermal deposits and host magmatic rocks in combination with geological characteristics of these deposits, the authors have reached the following conclusions： 1. Time intervals between the formation of host rock and the mineralization for fluorite, gold-silver, lead-zinc(copper)and tungsten-beryllium niobiumtantalum deposits are in order of tungsten-beryllium-niobium-tantalum (≈0×106a)6～3×106 a)6～60×106 a)6～70×106 a). Such time interval sequence is in agreement with the sequence of ore-forming sequence arranged in increasing S0298/di values (W, B, Mo, Sn, Nb, Ta |
