The statistical analysis was done for 177 circular structures interpreted from the remote sensing images of northwestern Guangxi Autonomous Region. The value feature of circular structures and the relationship between the circular structures and the gold minerogenesis were studied. The informations content of circular structures was calculated. The contribution of circular structures to find gold deposits was estimated using the "probability model". The statistic analysis result of the relationship between the circular structures and minerogenesis showed the deposit-finding probability in the areas of circular structures is 50 times than in the areas without circular structures. So, the circular structures in northwestern Guangxi Autonomous Region should be the favourable mark to find gold deposits.
