北祁连地区是华北板块和柴达木—祁连板块的对接地带,是我国一个重要的构造成矿带。其内已发现铜、铅、锌、铬、钨、铁、金、钴、锰等金属矿产地260多处。本文是在研究了北祁连地区主要金属矿床的时空分布、含矿层位、成矿期、控矿构造等的基础上,结合北祁连构造演化特征,按照成矿系列的学术思想将区内主要金属矿床划分为9个矿床系列。文中按时代顺序概述了每一成矿系列矿床的基本特征、区域分布、主要成矿地质作用及产出构造环境,并根据对成矿系列的初步研究,总结了北祁连地区区域成矿作用的特点。
The North Qilian area is the docking area between the North China Plate and the Qaidam-Qilian Plate and is an important structural metallogenic belt in China. It has found more than 260 copper, lead, zinc, chromium, tungsten, iron, gold, cobalt, manganese and other metal deposits. Based on the study of the temporal and spatial distribution, ore-bearing strata, metallogenic stage and ore-controlling structure of the major metallogenic deposits in the North Qilian area, combined with the tectonic evolution characteristics of the North Qilian, according to the academic thought of the metallogenic series, The main metal deposits are divided into nine mineral deposits. In this paper, the basic characteristics, regional distribution, major metallogenic geology and tectonic setting of each metallogenic series ore deposit are summarized in chronological order. Based on the preliminary study on the metallogenic series, the regional mineralization in the North Qilian area is summarized specialty.
