糜棱岩化

It can be subdivided into coarse mylonite, mylonite and ultra-mylonite for its increasing mylonitization. On the other hand, the recrystallization

随着糜棱岩化程度的增高可将糜棱岩进一步划分为粗糜棱岩、糜棱岩、超糜棱岩。

The ductile shear belt is composed of geneiss,mylonited rock,mylonite and ultramylonite,the obvious change of mineral components and chemical compositions help to activate in gold ores,in proper temperature and pressure conditions,it is filled,and deposited in foliation strcture,forming ductile shear belt gold deposit.

Fault rocks, microstructures and homogeneous temperature (concentrated around 160℃) of fluid inclusions in the quartz veins shows that the fault belt mainly underwent shallow brittle deformation and the highest-grade dynamic metamorphic rock is mylonitized sericite phyllite.

Calculations based on Grosens'component-volume equation show that,wit the intensification of mylonitization,increasing amounts of SiO_2 and FeO are brought in,which is geologically expressed as intensified silicification and pyritization.

This paper deals with and summarizes the research and importance of ductile shear zones and presents the future direction and aim for the research of the ductile shear zones around the world. Four aspects of studies of the ductile shear zones have been proposed in this paper as follows:(1) The stress environment including the mineral assemblages, deformation, stress-shearing parameters;(2) The major element sequence and activation under condition of stress;(3) The variations of trace elements and REE, their transportation distributions under strong natural deformation as well as variations of mineral crystal parameters, which can also control the element changes during the ductile deformation;(4) The relationship between element migrations, activation and stress, which will present the new evidences for the studies of dynamic diagenesis and mineralization as well as the studies of evolution of ductile shear zones developed in middle and low levels.(5) The analysis of elements and isotopes in mylonites on the micro-scale are crucial for the understanding of component migrations during the mylonization.
