| 摘 要： | 通过小秦岭金矿带不同地质体岩石稀土地球化学特征的研究，认为太华群岩石的变质作用是成矿元素活化迁移的主要因素。不同地质体具有继承性演化特点和成因联系，且成岩、成矿关系密切；晋宁期和燕山期等后期花岗岩体为太华群在地壳深部部分熔融形成的；金矿床成矿物质的活化迁移和富集时代在晋宁期以前，为熊耳期。从而为本区某些地质问题的解决，提供了新的有价值的信息

| Abstract: | Based on the studies of geochemical characteristics of REE in different types of rocks, it is concluded that the metamorphism of the Taihua group is the main factor for the ore forming elements to mobilize and remove; that the different geological bodies show characters of inheritable evolution and genetic relations, and close relations to teh petrogenesis and mineralization; similar REE distribution pattern that the host granites are generated by part melting of the Taihua group in the deep crust; that the age of mobilization, removal and concentration of the ore forming matters is the Xionger period before the Jinning period. |
