| 摘 要： | 以１：５万茶洛、阿冬纳幅为实例，介绍了优地糟区花岗岩单元。超单元填图工作概况。详细论述了解体岩基的方法及不同先后侵位的岩石单元的差异性在单元－超单元划分的可信度研究中论述了划分、归并的依据，并从大量的测试数据及其演化规律中印证了宏观上解体的正确性。作者认为在优地槽区也同样能开展花岗岩单元－超单元填图工作。

| Abstract: | Exemplified by Chaluo and Adongna Sheets on a scale of 1:50,000, this paper outlines the geologieal mapping of granite unit-superunit in eugeosynclinal realm, discusses the method disintegrating batholith and the difference between various units. Basis for conviction study on the unit-superunit division is expounded. Petrocheiniecal, REE geochmical and microelement geochemical data and their evolution prove the disintegration of batholith to be correct. Granite unit-superunit method may be applied to geological mapping in eugeosynclinal realm. |
