The wallrock alterations of gold mineralization include silicification,pyritization,sericitization,potassic alteration,chloritization and carbonitization.
Zhaocun bentonite deposit oringnated from tuff rich in volcanic hyalocrystalline,which underwent hydrolysis and alteration in Changxing county,Zhejiang province.The deposit has middle scale.
The metallogenic material was from deep alkalic basaltic magma, and the pulsatory invasion was the necessary metallogenic condition of the ore deposit.
The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits.
The orebody is controlled by SN, NW faults and fissures, the ore deposit belongs to magmatic hydrothermalism-stratabound and compound magmatic hydrothermalism type one.
