Abstract:

It is known that silver ore resources are rich in China，and metallogenic condition is superior with good prospecting potential，particularly for the Da Hinggan Mountains.For example，in recent years，several large and super-large silver deposits were found at the northern and southern-middle parts of the Da Hinggan Mountains.In the present study，based on the results of silver ore prospecting at southern part of the Da Hinggan Mountains and its ore-forming geological background，main ore-controlling elements，etc，the types of silver deposits in Chifeng region were summarized and sectioned.Overall，the study region can be sectioned into six types，namely，thermal fluid vein type，porphyry type，epithermal type，exhalitive-sedimentary type，structure altered rock type.In addition，the exploration process of silver deposits was elaborated，finally，the prospecting thoughts for silver polymetallic deposit was summarized，which has important significance for future prospecting.

Key words: silver deposit, mineralization type, prospecting thought, Chifeng region
