| 摘 要： | 铁架山花岗岩岩性不均匀。并具片麻理。长期以来被认为是混合岩或混合花岗岩。经过显微构造分析确认,铁架山花岗岩是经过强烈韧性变形的岩浆型花岗岩。它共经历了岩浆阶段、韧性变形阶段、静态重结晶阶段、脆性变形阶段等4个演化阶段。

| Abstract: | The lithology of the Tiejiashan granites has a gneissosity and poor uniform distribution. For a long time, it is considered that they are migmatites or migmatitic granites. Through the microstrueture analysis, it is affirmed that the Tiejiashan granite belongs to magmatic granite which underwent highly ductile deformation involving four stages, i. e. magma, ductile deformation, static recrystallization, brittle deformation. |
