The Daning multi-stage intrusive complex mainly consists of quartz diorite, granodiorite and monzo- granite, in which mafic microgranular enclaves （MME） are well developed, especially in granodiorite. Shape, tex- ture and fractals characteristics of enclaves that double logarithmic coordinates of circular diameter of work area and number of MME has a good linear relation （ p 〉0.75）, show MME and the host rocks follow a fraetal model, being indicative of MME of magma mixing origin. It can be speculated that mixing is heterogeneous in space from that the fractal dimension of MME in the interior and margin of granodiorite is 1.293 and 0.991 respectively. A consistent lineation structures between MME and the host rocks suggest that felsic magma had partially crystal- lized before injection of mafic magma. Maybe convection is the main driver for dispersedness, deformation of MME and mixing heterogeneity.
