浙江诸暨芙蓉山破火山口东缘萤石矿床控矿构造特征研究OA

The Furongshan caldera is located in the Zhuji-Yiwu area of Zhejiang Province,at the junction of the Jiangshan-Shaoxing suture zone and the Lishui-Ningbo deep fault,within the northwestern segment of the southeastern Zhejiang volcanic belt.Circular and radial faults are well-developed around the caldera,with numerous dykes intruding along the circular fault systems.This study focuses on the structural relationship between fluorite deposits and the eastern margin of the Furongshan caldera,systematically analyzing the structural control characteristics of the fluorite mineralization.Research results indicate that the fluorite deposits are primarily controlled by the circular and radial faults of the Furongshan caldera,with a formation age of the Late Cretaceous,closely linked to regional volcanic activities.In this area,analogous ore-controlling structures are widely developed,providing favorable metallogenic conditions and significant exploration potential for fluorite deposits.Notably,fluorite exhibits symbiotic or associated relationships with polymetallic minerals,offering a new perspective for regional polymetallic deposit exploration.
