安徽庐枞盆地小包庄与泥河铁矿床地质特征及成矿机制对比研究
Comparative study on geological characteristics and mineralization mechanisms of the Xiaobaozhuang and Nihe iron ore deposits in the Lu-Zong basin,Anhui Province
摘要
Abstract
Based on previous studies,this paper systematically reviews the geological characteristics,mineralogical features,alteration patterns,and relevant geochemical indicators of the Xiaobaozhuang and Nihe iron ore deposits.It investigates the spatiotemporal relationship between these two deposits in terms of mineralization mechanisms,and concludes that both were formed by late-stage magmatic hydrothermal metasomatism during the Zhuanqiao cycle.The ore-forming hydrothermal fluids migrated upward along fractures and interacted with Triassic gypsum bed.Although the two deposits exhibit similar enrichment characteristics of ore-forming elements,their geochemical indicators show no discernible evolutionary trend.This suggests that they represent two independent deep-seated ore bodies,with their spatial distribution controlled by regionally fault-induced differential emplacement of magmatic hydrothermal systems.关键词
