| 摘 要： | 以往本区花岗岩多被确定为华力西晚期花岗岩或燕山期花岗岩、印支期花岗岩比较少见。本文以同位素年龄为依据。将本区以往确定的华力西晚期的板石花岗岩确定为晚印支期花岗岩，并详述了其基本特征和侵入期次。初步探讨了成因类型。

| Abstract: | In the study area, the age of granite was mainly defined as the late Variscan and Yanshanian , and Indo-sinian granite is relative rare. On the basis of the isotopic age, the late Variscan Banshi granite is redefined as the late Indo-sinian granite. Meanwhile, its basic characteristics, intrusive periods as well as genetic types are discussed in this paper. |
