Abstract Qinghai Province is located in the northeast of Qinghai-Xizang plateau，Northern Qinghai Province belongs to Qinqikun orogenic system, Southern Qinghai Province belongs to Sanjiang orogenic system, in terms of metallogenic belt， Northern Qinghai Province belongs to Qinqikun metallogenic domain, Southern Qinghai Province belongs to Tethys metallo? genic domain, graphite deposit is relatively deposits are mainly distributed in Qaidam peripheral re? gion of Qinqikun metallogenic domain in Northern Qinghai Province，proterozoicmetamorphic old strata is widely distributed in the area, the metallogenic geological conditions is favorable，many regional metamorphism type crystalline graphite deposits (points) are found, the prospecting prospect is the newly geological investigation results and some related study results of Qaidam peripheral region, metallogenic geological background, distribution of graphite deposit are discussed, geolog? ical characteristics, metallogenic regularity, metallogenic prospect area, metallogenic geological conditions, metallogenic ep? och, metallogenic temperature and pressure conditions, carbonaceoussource, deposit genesis and metallogenic m
