福建碧田矿床是成因上与燕山晚期次火山岩有关的铜金银矿床。含银黄铜矿产于该矿床的金银矿石和银矿石中。含银黄铜矿呈粒度约0.004—0.07mm的他形粒状与银金矿、金银矿、自然银、辉银矿、黄铜矿、闪锌矿等共生,在空气中极易氧化。含银黄铜矿的银含量变化在1.045％—14.273％之间,平均值为4.37％。与黄铜矿比较,含银黄铜矿中疏含量变化不大,但铁与银有反消长关系。含银黄铜矿形成于成矿作用晚期银大量富集的金银多金属硫化物阶段和自然银-石英阶段。成矿温度在120—260℃之间,硫逸度1gf_(s_2)=-11.6—-19.5。
The Bita deposit in Fujian is a copper-gold-silver deposit that is genetically related to the late Yanshanian secondary volcanic rocks. Silver-bearing chalcopyrite is found in the gold, silver and silver ores of the deposit. Silver-containing chalcopyrite granularity of about 0.004-0.07mm he shaped granular silver and gold, gold and silver ore, natural silver, silver, chalcopyrite, sphalerite and other symbiotic, easily oxidized in the air. Silver content of silver chalcopyrite varies between 1.045% -14.273% with an average of 4.37%. Compared with chalcopyrite, silver content in chalcopyrite does not change much, but iron and silver have anti-growth relationship. Silver-bearing chalcopyrite was formed during the late stage silver-metal-rich polymetallic sulphide stage and natural silver-quartz stage in the late stage of mineralization. The metallogenetic temperature is between 120-260 ℃ and the sulfur fugacity is 1gf_ (s_2) = - 11.6--19.5.
