| 摘 要： | 近年来，旬北铅锌矿集区发现了长达近百公里的铅锌矿带及钠长石岩带，铅锌矿多顺层整合产在以志留系为主的细碎屑岩中，沉积特征明显，含矿层内热水沉积岩发育，围岩蚀变不明显，矿体下部钠长石岩发育，底板多见铁碳酸盐岩，矿层内常见热水沉积微晶硅质岩，矿石多具块状、层状、层纹状构造。热水沉积可能是铅锌矿主要成矿方式，成矿物质来自盆下深处。

| Abstract: | In recent years,a lead-zing mineralized zone has been found approximately 100m long in the lead-zinc concentration area of the north of Xunyang.Lead-zinc mineralization occurs in fine-grained clastic rocks mainly in the Silurian system at parallel to the stratigraphy.It is characterized by evident sedimentation,well developed thermal water sediments,unclear wall-rock alteration,well developed albite at the bottom of orebodies and iron-cabonate found at the footwall.The ore beds appear in massive,bedded and ... |
