秦巴地区古代银矿分布信息及成矿区划

Information of Acient Silver Ore Distribution and Metallogenic Areas in Qinling-Bashan Region

秦巴地区有丰富的银矿资源。本文收集正史及有关地理著作中的历史信息,列出秦巴山系所经甘、陕、豫3省境内产银县36个,产铅县7个。分析古代银(铅)矿分布特点,结合现代地质科研成果。划分出3大银矿成矿带、两个银矿成矿亚带和7个银矿成矿区。简述了赋矿地层、岩性、银矿类型等特征,并对该区找银提出见解。

There are abundant silver ore resourses in Qinling-Bashan Region. Historical information is provided by historical and old geographcal works.36 counties produced silver ore and 7 counties produced lead ore are listed in Shaanxi, Gansu (Henan included) and Qinling-Banshan Reg- ion. The regular distribution of acient silver(lead) ore is together ana- lysed. The author describes modern geologinic achivements to classify three big metallogenic zones, two metallogenic subzones and 7 metallogenic areas (Fig. 2.), and to recount contained ore stratifications, lithological chara- cters and types of silver ore. suggestions on search for ore are also posed in Qinling-Bashan Region.
