Abstract: The Maochaoying-Dushu area on the southern margin of the North China block is a Proterozoic-Paleozoic aulacogen, where there occur littoral, neritic and shelf continental-margin clastic-carbonate formations of the Guandaokou Group, Luanchuan Group and Taowan Group. Strong shallow-source volcanic eruption (exhalation) gave rise to multi-layer chert bands (nodules), siliceous rocks and silver-lead-zinc mineralization-bearing layered skarn in the area. This area is a relatively typical district where a geochemical abrupt change zone and a geophysical gradient zone intersect. The earth's mantle and crust beneath the area are enriched in Mo, Pb, Zn and Au. From the ore-forming geological conditions of silver-lead-zinc-gold deposits, it is inferred that the area has good ore prospects.
