| 中文摘要: |
| 内蒙古浩布高锡多金属矿田位于大兴安岭南段黄岗-甘珠尔庙成矿带中部，矿田内分布有红岭铅锌矿等8处铅锌矿床。为研究该矿田内已发现的铅锌矿与锡矿的关系以及成矿系统演化特征，本文从时间、空间、成矿构造、岩浆演化、矿化分带、成矿机制等方面对其进行分析。研究认为：浩布高锡多金属矿田锡与铅锌属同一成矿系统，明确了矿田以萤石矿为边界，确定了成矿地质体为燕山晚期细粒花岗岩，建立了矿田“三位一体”成矿地质模型，并指出了青松沟和额吉锡盛2处多金属找矿靶区。 |
| 英文摘要: |
| The Haobugao tin polymetallic ore field is located in the middle of the Huanggang-Ganzhuermiao metallogenic belt in the southern part of Daxinganling. There are eight lead-zinc deposits such as the Hongling lead-zinc deposit in the ore field. The purpose of this paper is to study the relationship between the known lead-zinc deposits and tin deposits and the evolution characteristics of the metallogenic system, involving spatial-temporal distribution，metallogenic structure, magma evolution, mineralization zoning, and metallogenic mechanism. The study suggests that tin and lead-zinc belong to the same metallogenic system. It is clarified that the ore field is bounded by fluorite deposit, and the ore-forming geological body is Early Cretaceous fine-grained granite. A "trinity" ore-forming geological model of the ore field is established, and two tin polymetallic prospecting targets in Qingsonggou and Erjixisheng are delineated. |
