摘　　要：草辗铷多金属成矿区位于华北北部陆缘增生带镶黄旗-赤峰火山岩型被动陆缘与华北地块阴山隆起带的结合部位,岩浆活动强烈,主要表现为强烈的火山喷发和岩浆侵入。研究区在漫长的地质发展史中,经历了多机制、多期次的构造作用和火山活动,同时为成矿提供了很好的物理、化学条件,形成了诸多金银多金属、铁、铷铌稀有金属等金属矿产。本文在研究前人工作成果的基础上,结合对已发现矿(床)点规模大小及物化遥异常特征的综合分析,归纳总结研究区内地质背景、控矿因素、成矿规律和找矿标志,以期为研究区内找矿勘查提供参考。The Caonian rubidium polymetallic mineralization district is located in the junction of Xianghuangqi-Chifeng volcanic passive continental margin and Yinshan uplift belt of the North China Block.Intense magmatic activity,characterized by vigorous volcanic eruptions and magma intrusions,has occurred in this area.Throughout its long geological history,the region has undergone multi-mechanism,multi-stage tectonic and volcanic activity,creating favorable physical and chemical conditions for mineralization.This has led to the formation of various mineral deposits,including gold-silver polymetallic ore,iron ore,and rubidium-niobium rare metal ore and other metal minerals.Based on previous research results and a comprehensive analysis of the scale and geochemical anomalies of known deposit or ore occurrence,this paper summarizes the geological background,ore-controlling factors,metallogenic regularity,and prospecting indicators in the study area,aiming to provide guidance for mineral exploration and prospecting in the region.
