On the basis of observatioal data of more than one hundred faults in China and the apparent correlation between fault and megascopic structure, we have studied the zoning of the cataclastic rocks caused by different kinds of faults, and their characteristic types in China. Four distinct zones are recognized in a compressive faults from the centre outwards: crush conglomerate (fault gouge and gravel zone); mylonite——compressed schistose zone; granulated rock——structural lens zone; cataclasite——closely apaesd fracture zone. In addition to the observations in the field, an analysis of the zoning in terms of mechanical principle, experimental determination and tectono-geochemistry has also been made. The zoning reveals the layering and banding of geological bodies, which are of some theoretical and practical significance in mineral exploration.
