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
賦存於中元古宙長城系常州溝組的洞子溝銀礦床和尖寶山金礦床是由密雲-都山變質核雜巖構造體系所控制的一組礦床。其成因為中元古宙火山巖漿活動形成的沉積礦源，后經中生代的變質核雜巖構造巖漿體系疊加改造而成。洞子溝銀礦床具有層控迭加改造的特點尖寶山金礦床則具有破碎蝕變巖型礦床的特點。 -
