在野外地质工作过程中,经常可以见到挤压断裂带和岩石剪切滑动面上出现碳质.如四川盐边鲰鱼西番田断裂,震旦系灯影组白云岩与前震旦系盐边群之断层接触带上,出现有1.5米宽的碳化糜棱岩化之破碎带;四川会理杨合五至河口一带的若干断层面上,均有不同程度的碳化现象.这种现象笔者在陕西商县一丹凤地区白云质灰岩断裂带中也有见及.包括在岩浆岩的滑动镜面上的碳质薄膜.四川冕宁老麻沟花岗岩与流纹岩之断层接触带上的碳化糜棱岩等都是最好的例证.
During the geological work in the field, carbonaceous rocks can often be seen on the crustal faults and on the shear and sliding surfaces of rocks, for example, the Xuantian fault of the anchovy catfish in Sichuan Province, the dolomite of the Sinian Dengying Formation and the former Sinian salt margin group Of the fault contact with the emergence of a 1.5-meter-wide mylonitization of the crushing zone; Sichuan will be Lihe five to the mouth of the river a number of fault surface, have different degrees of carbonation phenomenon.This phenomenon in Shaanxi Also seen in dolomitic limestone fault zones in the Shangdan-Danfeng area, including carbonaceous thin films on the sliding mirror of magmatic rocks, carbonitriding on the fault contact zone of the Morang granite and rhyolite Rock is the best example.
