The linkage between the Jiawula-Chaganbulagen Ag-Pb-Zn and adjacent porphyry Mo-Cu mineralization, Inner Mongolia, northeast China

•The Jia-Cha ore field belongs to the IS epithermal-porphyry system.•Micro-inclusions of sulfide display a similar zonation with the main metals.•The ages of mineralization for the epithermal-porphyry system is about 133–135 Ma.•The epithermal Ag-Pb-Zn deposits are genetically related to a porphyry Mo-Cu system.
