摘要:
腾冲地区岩浆-热液成矿作用形成了东、中、西三个矿带,以及滇滩-大硐厂-红岩头铅锌锡铁硅灰石矿、铁窑山-小龙河锡钨铁铅锌矿两个重要矿集区。本文以前人研究资料为基础,按矿床成矿系列理论研究方法,厘定了该地区与燕山期花岗岩有关的矿床成矿系列及亚系列,系统总结了该地区与燕山期花岗岩有关的矿产资源时空分布规律,研究结果表明燕山期是本地区最为重要的岩浆-热液成矿作用时期,该地区锡、铅、锌、铁、铜、钨、金、银、硫铁矿、硅灰石、萤石、宝石、云母、红柱石、稀土及稀有金属矿等矿产主要与燕山期花岗岩有关,构成了特定的与燕山期花岗岩有关的矿床成矿系列,并根据花岗岩分带、矿床空间分布、矿化组合、成矿时代的不同,进一步分为3个矿床成矿亚系列,总结了矿床成矿亚系列特点,分析了该地区的找矿潜力,指出了找矿远景区,深化了对腾冲地区锡(钨)、铅锌、铁、硅灰石、铜等矿产成矿规律认识,为今后在该地区从事地质找矿、教学和科研等方面提供参考。

Abstract:
The Yanshanian magmatic-hydrothermal mineralization formed three ore belts and two important ore concentration districts of Diantan-Dadongchang-Hongyantou lead-zinc-tin-iron-wollastonite deposits and Tieyaoshan-Xiaolonghe tin-tungsten-iron-lead-zinc deposits in Tengchong area. Basing on the previous research and the theoretical methods of metallogenic series, this paper defines the metallogenic series and sub-series related to Yanshanian granitoids and systematically summarizes the spatial-temporal distribution regularity of mineral resources related to Yanshanian granitoids in Tengchong area. The results show that the Yanshanian period is the most critical period for magmatic-hydrothermal mineralization in Tengchong, all ore deposits of tin, lead, zinc, iron, copper, tungsten, gold, silver, pyrite, wollastonite, fluorite, gem, mica, andalusite, rare earth elements, and rare metals are mainly related to the Yanshanian granitoids, forming the specific metallogenic series of Yanshanian granitoids. According to the zonings of granitoids, the spatial distribution of deposits, and ore-forming epochs, the metallogenic series of Yanshanian granitoids in Tengchong area could be further divided into three metallogenic sub-series. By characteristics of the metallogenic sub-series, this paper has summarized and analyzed the potential prospecting prospects in the region. It is hoped that this paper can deepen the understanding of metallogenic regularity of tin (tungsten), lead-zinc, iron, wollastonite, and copper deposits in Tengchong area, providing a reference for geological prospecting, teaching, and scientific research in the future.
Key words:  polymetallic tin ore  metallogenic series  Yanshanian granitoid  Tengchong
