CHARACTERISTICS OF DUCTILE SHEAR ZONE AND GRAPHITE MINERALIZATION IN THE SOUTH OF YUANMOU METAMORPHIC CORE COMPLEX
Four ductile shear zones have been identified through the geological survey and drilling work in the southern part of the Yuanmou metamorphic core complex.The macroscopic features of them include mylonite and mylonitized rocks,stretching lineation,S-C fabric,sharp-edged folds,etc,whereasthe microscopic features include quartz dynamic recrystallization,rotational porphyroclasts,asymmetric pressure shadows,mica fish and microscopic sharp-edged folds.The drilling data show that the ductile shear zone is a good ore-bearing space of the crystalline graphite ore body.
