| 摘 要： | 依据甘肃西秦岭金矿富集区矿床和相关花岗岩的同位素年龄和稳定同位素数据,探讨了该区金矿床成矿作用与花岗岩成岩作用的关系及成矿物质来源。从数据显示,成岩和成矿作用均发生在侏罗纪;成岩年龄集中分布在200Ma~171Ma;大规模成矿作用年龄分布在195Ma~140Ma;成矿事件同步或略滞后于花岗岩浆活动;相关花岗岩是地壳物质重熔而成的S型;花岗岩浆侵入是该区金矿形成的主导因素;成矿物质和流体来源于地壳。

| Abstract: | The data of isotopic age and stable isotope for deposit and related granitic in the gold enrichment area of western Qinling of Gansu Province were collected, and the relationship between gold mineralization and diagenesis, and metallogenetic material source in this area was discussed. The statistics show that both mineral- ization and diagenesis occurred in Jurassic, diagenetic age is distributed in 220Ma- 171Ma, most in 200Ma- 171Ma; and big scale mineralization occurred in 195Ma-140Ma. Metallogenic event occurred in same time or a little late with granitic magmatic activity. Metallogenic material and fluid were from earth - crust, related granite is S- type ganitic magma that formed by crustal material remelting, and its and its intrusion is master factor which led to form gold deposit in this area. |
