| 摘 要： | 本文介绍近年来在浙西石耳山花岗岩区引进“花岗岩超单元─单元”理论进行的1：5万区域地质调查工作取得的成果。按同源岩浆演化序列的观点，通过野外工作和室内研究，解体了晋宁期石耳山复式花岗岩体。对划分出的30个侵入体，归并建立了四个单元，并进一步建立了石耳山超单元。通过对石耳山超单元花岗岩的岩石矿物学、岩石化学、地球化学等地质特征的分析研究，初步总结其演化特征，并同时探讨其成因类型，指出石耳山超单元花岗岩相当于S型花岗岩，应属上地壳硅铝层重熔岩浆的产物。

| Abstract: | This paper introduced the achievements of the 1: 50, 000 regional geological surveying in shiershan granite areas of Western Zhejiang, which was conducted with the theory of "granite superunit - unit" recently. According to the view of comagmatic evolutionary sequence and through the field work and laboratory research, the shiershan complex granite body of Jinning Stage was divided into 30 intrusive bedies, which were further incorporated into 4 units as well as a shiershan superunit. By analyzing and studying the geological features as mineralogy, litho chemistry and geochemistry of the shiershan superunit granite, the author preliminarily summarized its evolutionary features, discussed about its genetic type and pointed out that Shiershan su perunit granite was equal to the granite of S-type, which was product of remelting magma in the sial of upper crust. |
