This paper mainly deals with the mineralogical characteristics from which genetic information of Dongbeizai gold ore deposit is extracted. The metallogenic model of "pressure reduction caused by tectonic actiVity——gold provided by sedimentary rock——gold transported by circulated geothermal brine to enrich to ore" is established on the ore genesis. This deposit is an epithermal gold deposit which can be correlated to Ertaizi Au-deposit, Shanxi Province, Jinchangzi Au-deposit, Ningxia Autonmous Region and Karlin Au-deposit, US. Its surrounding areas and deep levels are all ecxellent potential areas for futher gold prospecting.
