Dongzigou ag deposit and jianbaoshan au deposit are hosted in the sandstone of middle - proterozoic suberathem, which are developed from the proterozoic sediment metal source - rocks formed during the meso - proterozoic volcanism and reworked by the mesozoic tectono - magmatism during the formation of the metamorphic core complexes in eastern hebei. the dongzigou ag deposit has the characteristics of reformed strata - bound origin, the jianbaoshan au deposit, located in the detachment fault, is the alterated rock type. both deposits have the similar wall - rock alteration, and show the same trace element behavior, and ree patterns. they are the results of the multi - stage tectono - magmatism in the environment of continental extension in eastern hebei region. their mineralization depended on their wall rocks and relative location in metamorphic core complexs
