| 摘 要： | 本文证实了金堆城钼矿区存存两种不同类型花岗岩,上地壳太华群和熊耳群的重熔形成老牛山、水仙台等改造型花岗岩体.而下地壳及上地幔分熔形成金堆城等与钼矿有关的同熔型花岗斑岩,两类花岗岩在成因上直接联系.此外还探讨了东秦岭A型俯冲与本区花岗岩成因的联系

| Abstract: | It is suggested in this paper that there are transformation-type granite and syntexis-type granke in the famous Jinduicheng molybdenum mining area based on the study of accessory minerals, stable isotopes, REE distribution and REE quantitative analog. The transformation-type granites are formed by remelting of Taihua and Xionger groups in the upper crust, but the synteyis-type granites are formed by partial melting of the upper mantle and lower crust. There are no direct genetic relations between large granite atholith and small porphyry stocks. Granites of Yanshanian period in this area are ascribed to A-type subduction movement between the South-West platform and North-China platform. |
