| Abstract:This paper discussed the geology and metallogeny of lead - zinc mineralization in the YaDu - - MangDongmetallogenic belt. Based on re2
gional geological and geochemical background and characters of known typ ical deposits and occurrences in the region, the lead - zinc mineralization rules
are summarized. The exp loration in the region shows that faults in the YaDu - - MangDong lead - zinc mineralization belt are the main ore - controlling
structures, ore - bodies in major fractures are mainly occurred as steep ly dipp ing veins, whereas and ore - bodies in nearby subsidiary fractures are mainly
stratiform. The fault activity strength is positively related with the lead - zincmineralization intensity. The geology, geophysical and geochemical anomalies
and mineralization concentration rules all suggested that there are exp loration potentials for discovering large lead - zinc deposits in the deeper section of
the YaDu, ShaoJ iWan and YangJueChangmining areas and also peripheral areas of the mines |
