摘　　要：龙门山中段清平磷矿床是中国重要的磷矿资源之一,本研究通过对磷块岩中胶磷矿的矿物学特征进行系统研究,旨在揭示胶磷矿的成因机制,探讨其在矿床形成与演化中的地质意义。采用了光学显微镜观察、矿物鉴定及扫描电子显微镜和能谱分析等技术手段,详细描述了磷块岩中胶磷矿的外观特征、组分和结构特点。研究发现,磷块岩中的胶磷矿以颗粒状或块状分布,常呈黄白色或淡黄色,主要矿物包括磷灰石、陨石矿、方铅矿等。胶磷矿与磷块岩基质之间呈现出复杂的接触关系,具有明显的界面反应。通过对龙门山中段清平磷矿床磷块岩中胶磷矿的矿物学特征进行系统研究,不仅可以加深对该地区矿床的认识,还能够为其他类似矿床的研究提供借鉴和参考。本研究为磷矿床开发与利用提供了科学依据,对促进资源可持续利用和保护环境具有重要意义。The Qingping phosphorite deposit in the mid-section of Longmen Mountain is one of China's important phosphorite resources.This study systematically investigates the mineralogical characteristics of resin phosphorite in the phosphatic rock,aiming to reveal its genetic mechanism and explore its geological significance in the formation and evolution of the deposit.Techniques such as optical microscopy,mineral identification,scanning electron microscopy,and energy-dispersive spectroscopy were employed to describe in detail the appearance,composition,and structural features of resin phosphorite in the phosphatic rock.The study found that resin phosphorite in the phosphatic rock is distributed in granular or blocky forms,often appearing yellowish-white or pale yellow.The main minerals include apatite,meteoric iron,and galena.Resin phosphorite exhibits a complex contact relationship with the phosphatic rock matrix,displaying evident interface reactions.By systematically studying the mineralogical characteristics of resin phosphorite in the Qingping phosphorite deposit of the mid-section of Longmen Mountain,this research not only deepens the understanding of the deposit in this region but also provides references for the study of similar deposits.The study provides scientific basis for the development and utilization of phosphorite deposits and is of great significance in promoting sustainable resource utilization and environmental protection.
