摘要
录龙铅锌多金属矿矿体赋存于古近系林子宗群典中组,其岩性为凝灰岩、安山岩等中酸性火山岩,是区域的主要含矿层位。地表可见的蚀变主要有绿泥石化、绿帘石化等;主要的金属矿物为方铅矿、闪锌矿、黄铁矿、镜铁矿等,非金属矿物有绿帘石、绿泥石、石英等。本文在综合的录龙矿区的成矿地质背景、控矿因素、物探、化探、遥感等特征的基础上,对矿区的成矿特征进行了系统的总结;初步探讨了矿化富集规律,并对成矿前景和找矿潜力进行了初步评价。
The Lulong Pb-Zn deposit occurs in the Dianzong Formation of the Paleogene Lizizong Group.The host rocks are tuff and andesite.The wallrock alterations are chloritization,epidotization and so on.Main ore minerals are galena,sphalerite,pyrite and specularite and main gangue minerals are epidote,chlorite and quartz.This paper systematically summarizes the metallogenic characteristics of the deposit and makes an approach to its metallogeny based on geological setting,ore control factors,geophysical and geochemical data and remote sensing information.
