Although the high degree of geological conditions at the Zhengxiangbai Banner-Zhenglan Banner region,geological work was at low level with great prospecting potential.It presented the lower Permian Sanmianjing Group upper rock section and the upper Jurassic Zhangjiakou Group three rock section,and the silver content was higher.Due to the violent volcanic eruption,the structure of the hydrothermal activities related to volcanism during later volcanic period,volcanic rock and contains showed a large amount of volatiles,which played an important role in activation,migration and enrichment of silver and other metals.On this basis, according to the research area of silver and silver point of geological characteristics distribution laws and the metallogenic geological conditions,the region was divided into two silver metallogenic prospect areas.Therefore, strengthen the study of the metallogenic conditions of volcanic rock was meaningful to promote silver ore prospecting in volcanic rocks.
