陆相红层型铜铅锌矿床与红层盆地热卤水成矿作用

摘要:
新疆乌恰县乌拉根超大型铅锌矿是中国发现的首个产于陆相红层盆地中的红层型铅锌矿床,对其成矿作用及成因有多种不同认识,但都将其归入现有的一些矿床类型,如喷流沉积型、砂岩型等,却均不能反映其独特的成矿环境与成矿作用。为此,在广泛收集和研究全国陆相红层盆地及其矿产的地质资料基础上,通过区域地质构造背景、含矿建造、矿床特征、控矿因素、成矿物质来源、成矿流体等方面对比分析,认为乌拉根铅锌矿与中国大量产于陆相盆地内红色建造中的红层铜矿,在矿床特征、控矿条件、矿床成因等方面具有高度的一致性,均为陆相红层盆地热卤水作用的结果,是同一类型的矿床。红层型矿床是地洼区的特有矿产,是地球地质演化到地洼阶段才出现的新的矿床类型,陆相红层盆地热卤水作用是一个完全独立的成矿系统,因此将其作为一个单独的矿床类型——红层型矿床是合理的,既具有重要理论意义,也具有重要的实践意义,为铅锌矿找矿开辟了新的方向和领域。

Red bed Cu-Pb-Zn deposits and mineralization of hot brine in continental red bed basin

Abstract:
The Wulagen superlarge lead-zinc deposit in Xinjiang is a red bed lead-zinc deposit discovered for the first in continental basin in China. There exists controversy concerning its mineralization and genesis, and different researchers have classified it as different existing types of deposits, such as SEDEX type and sandstone type. Nevertheless, these classifications can not reflect its specific metallogenic environment and mineralization. Therefore, based on collected and studied the geological data of the continental red bed basin and its mineralization through comparison and analysis of regional geological structure background, ore-forming material sources, characteristics of ore-controlling factors, ore-forming fluid and some other phenomena, the author holds that the Wulagen lead-zinc deposit is very similar to many red bed copper deposits in China's continental basins in such aspects as the deposit characteristics, ore-controlling conditions and deposit genesis, and hence they are the same type of deposits.The red bed deposit is a specific mineral resource in diwa (geodepression) region and a new type deposit in diwa epoch, and red bed basin's hot brine action is a fully independent metallogenic system. The red bed deposit is a unique deposit type which has important theoretical significance and practical significance. A new direction and field are therefore opened for the prospecting of lead-zinc deposits.
