This paper summarized the initial deposit formation mechanism, considering the mineralization stage benefits from several metallogenic stages magma activities, early intermediate-acidic rock rising and injection, then happened contact metasomatism with carbonatite, forming the early stage skarn, after several tectonic reworking, magmatic rock of ore field. The stratum happened massive tectonic deformation, forming type of "M" non-overturned fold with almost south-east of trend, later the hydrothermal solution injects again along with the axial plane cleavage of fold, about the ore enrichment in fracture and the turning of loose part, carbonaceous slate of diggings have a very good effect of shield. The Dongzhongla deposit is the typical type of skarn and lead-zinc deposit. This paper raises a metallogenic model, regarding as the key point of ore prospecting in middle east of diggings where has no undertaking to work until now, has reference value for ore-prospecting survey in this diggings.
