摘要
本文在广西沙坡饰面花岗岩矿野外调查及钻探工程基础上,对花岗岩样品进行化学成分、放射性、物理性能等分析,总结矿床地质特征、分析矿床成因。结果表明,沙坡饰面花岗岩矿分布于志留纪岩体,矿体规模较大,岩性主要为浅灰色、灰黑色、浅红色二长花岗岩。饰面花岗岩的放射性、物理性能均满足饰面石材使用要求。饰面石材荒料率18.84%,板材率28.25m^(2)/m^(3),具有较好的装饰效果。饰面花岗岩属高分异过铝质高钾钙碱性S型花岗岩,形成于陆内碰撞造山环境。
In order to summarize the geological characteristics of the Shapo ornament granite deposit and analyze the genesis of the deposit in this paper,the chemical composition,radioactivity and physical properties are analyzed on the basis of field geological survey and drilling exploration.It is shown that the Shapo ornament granite deposit was hosted in Silurian monzogranite with large orebody scale.The main color characteristics of alternating stripes composed of gray black,light gray and light red.Radioactivity and physical properties meet the requirements of ornamental stone.The rate of quarry stone is 18.84% and the rock plank ratio is 28.25m^(2)/m^(3).The rock has better decorative effect after polishing.The data show that monzogranite belongs to S-type granite with high differentiation and high-K calc-alkaline series.The monzogranite probably was resulted from partial melting of crust due to the Caledonian orogeny.
