| 摘 要： | 非硫化锌矿床通常被误称为“锌的氧化物”矿床。由于湿法冶金学的发展, 这类矿床正在成为引人注目的勘查目标。该类矿床通常被划分为浅成和深成两种类型, 浅成锌矿床是非硫化物锌矿床最常见的类型, 深成非硫化物锌矿床主要有构造控制交代矿体和富锰喷流型层状矿体。甘肃代家庄菱锌矿床为西成中泥盆统新发现的一个大型矿床, 不同于一般的浅成非硫化物锌矿床, 可能为国内一种新类型的非硫化物锌矿床。

| Abstract: | Nonsulfide zinc depositswere usually mistaken as oxidation ores of zinc. Because of the development of hydrometallurgy, these ores have been paid attentions as significance exploration targets now. The nonsulfide zinc deposits are divided into two types of supergene and hypogene nonsulfide zinc deposits. The former is the most common, and the latter mainly includes structural controlled metasomatic deposit and manganese-enriched jet-type layered deposit. The Daijiazhuang zinc deposit of Gansu Province is a newly discovered large deposit in the Mid Devonian of Xichen. This deposit is different from normal supergene nonsulfide zinc deposit, and may be a new type of nonsulfide zinc deposit in China. |
