【摘要】：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。
[Abstract]:The characteristics, distribution and genesis of magnetic marine volcanic metamorphic rocks in the southern part of Qingchuan, Longmen Mountain, Sichuan Province are discussed, which provide the basis for the development and utilization of magnetic stone for decoration. Through the comprehensive geophysical exploration of magnetic method, high density electrical method, surface trough exploration and deep drilling, it is found that magnetite mineralization rocks in this area are very common, and the stone resources are huge. Based on the study of the rock structure, mineral composition and chemical composition of magnetic volcanic metamorphic rocks (mainly magnetic fine-blue rocks and keratophytes), it is considered that the magnetic marine volcanic metamorphic rocks experienced spillage, rapid cooling and condensation diagenesis, and submarine self-metamorphism. And subsequent regional stress thermal metamorphism; The magnetite in the rock is fine in size and wrapped in feldspar microcrystals and is not easy to be oxidized, which results in the preservation of the magnetic properties of the rock. The magnetic marine volcanic metamorphic rock color, hardness, size and so on are suitable for magnetic decorative stone. The present situation of biomagnetic medicine and the application prospect of decorative magnetic stone are briefly analyzed.
