火山及火山沉积作用与矿床的关系,一向没有得到地质学者足够的注意。近年来苏联学者在乌拉尔铜矿区及阿尔泰多金属矿区的精密研究,已获得了越来越多的资料,证明二者之间具有密切的成因关系。细碧角斑岩系与黄铁矿型铜矿的发育,矽酸岩交代作用与铅锌矿床的生成,不但在矿床的成因类型上已确定不够,并且还能依据这种关 The relationship between volcano and volcanic sediments and the deposit has never been paid enough attention by geologists. In recent years, the sophisticated studies of Soviet scholars in the Ural copper mining area and the Altai polymetallic mining area have gained more and more data, proving that there is a close genetic relationship between the two. The development of the Xipeijuan porphyry and the pyrite-type copper deposits, the silicate metasomatism and the formation of lead-zinc deposits have not only been determined not enough in the genetic type of the deposit, but also on the basis of this
