探讨四川龙门山青川南部地区磁性海相火山变质岩产出特征、分布及成因，为装饰用磁性石材的开发利用提供依据。通过磁法、高密度电法综合物探，地表槽探和深部钻探，查明本区磁铁矿化岩石极为普遍，石材资源储量巨大。结合对磁性火山变质岩（主要是磁性细碧岩和角斑岩）的岩石结构、矿物组成与化学成分研究，认为磁性海相火山变质岩经历了溢流喷出、快速降温凝结成岩、海底自变质，及之后的区域应力热变质等过程；岩石中磁铁矿粒度细小且被长英质微晶包绕而不易被氧化，致其岩石磁性得以保存。本区磁性海相火山变质岩的颜色、硬度、块度等均适合做磁性装饰石材。对生物磁医学现状及装饰用磁性石材的应用前景进行了简要分析。

This paper discusses the characteristics,the distribution and the genesis of the magnetic marine volcanic metamorphic rocks in the south of Qingchuan of Longmen Mountains and provides the basis for the development and utilization of the decorative magnetic stone.By the magnetic method, the comprehensive geophysical exploration by the high-density resistivity method, the groove exploration of the surface,and the deep drillings,it is found out that the magnetite mineralization rocks in this area are extremely common,having a huge reserves of resources.Combined with the studies of the rock structure,mineral composition and chemical composition of the magnetic volcanic metamorphic rocks (mainly magnetic spilite and keratophyre),this paper illustrates that the magnetic marine volcanic metamorphic rock has undergone the overflow jet,the rapid cooling condensation diagenesis, the metamorphism of the sea bottom, followed by the regional stress thermal metamorphism and that the magnetite particle size is fine and small.The particles are rounded by felsic microlites and not easy to be oxidized,so the magnetism of the rocks is preserved.In this area, the color,hardness,etc of the magnetic marine volcanic metamorphic rocks are suitable for making magnetic decorative materials.The present situation of the biological magnetic medical science and the application prospects of the magnetic ornamental stones are briefly analyzed.
