该岩体已变形改造为线状花岗质片麻岩体。除残留少量的岩浆流动组构外，主要表现为岩体定位后期或固结稍后的高温固态变形；以强烈的条带状片麻理发育为特征，并发育流褶皱、面理置换、小型韧性剪切带等。斜长石、钾长石多呈眼球状、条带状，为动态重结晶集合体；石英多呈矩形带状；变形温度在７００℃～５５０℃。应变测量显示其变形为压剪应变形，ｖ＝０．１９～０．５８，强度ＥＳ＝１．４６～１．２２。该岩体的变形揭示了该区晋宁期区域变形的特点和强度，并限定了其峰期变形时间。
The rock mass has been transformed into linear granitic gneiss body. In addition to a small amount of residual magma flow structure, the main features of the post-or post-consolidation solid rock later high-temperature solid deformation; characterized by intense strip-shaped piece of development and flow folds, face replacement, small toughness Shear band and so on. Plagioclase, potassium feldspar mostly spherical, banded, dynamic recrystallization aggregates; mostly rectangular ribbon of quartz; deformation temperature 700 ℃ ~ 550 ℃. Strain measurements show that the deformation is the shear deformation, v = 0.19 ~ 0.58, the strength of ES = 1.46 ~ 1.22. The deformation of the rock mass reveals the characteristics and strength of regional deformation in Jinning period and defines the peak deformation time.
