Abstract: There are many types of ore deposits in the Wanzijie ore section of the Laochang ore field. Themain factors for ore formation are the favorable configuration of the lithology, ore structure and magmaticactivity, which control the output of the ore deposit. Applying traditional geological theories, the paperstudies the geological characteristics, ore-controlling conditions, and ore body morphology of the areathrough the analysis of ore-forming geological conditions, geological characteristics and metallogenic regu.arity of the ore section. Having a clear view of the ore-controlling factors can shed insights on the futurework about geological prospecting in the area.

Key words: Wanzijie ore section, geological characteristics of ore deposits, ore-controlling conditions;metallogenic regularity
