摘要
Abstract
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.关键词
