A PRELIMINARY RESEARCH ON THE PHYSICAL CONDITIONS CONTROLLING THE FORMATION OF MINERALISED MYLONITE IN SOME MINE BREAK ZONE

Liang Liang Zhong zhijun (department of geolgy)  
In this paper, physical conditions are estimated using the features of microstructure and fabrics in mineralised mylonite and dynamically recrystallited grain size, subgrain size, dislocatoindensity and deformed rocks. The obtained results are temparature 300℃, Pressure 400MPa, differential stress 46MPa and deformation rate 4.7×10~(-12)/s. These data of mylonite are larger than those of the rocks around, so we may use these results to explain the close rela tions between the mylinite and uranium deposits both on the space and time.
