补充资料:花岗石
      岩浆岩的一种,主要由长石、石英和云母所组成。
  
  花岗石按所含深色矿物的不同,分为普通花岗石、黑云母花岗石、角闪花岗石、辉石花岗石等。开采花岗石一般用钢丝绳锯法。近年来,出现了密集排眼法和火焰喷射法等新工艺。火焰喷射法开采的石块切缝整齐,不生暗伤,生产效率高。采下的石块经粗整后称为荒料,再经人工钻眼打锲或机器锯割,制得所需规格尺寸的块材、板材;用铣石机或旋床加工,成为圆柱形或弧形体;最后人工斩凿粗、细岩状纹,或用机器研磨、抛光,使表面晶莹光亮。
  
  花岗石结构均匀致密,坚硬耐磨,耐酸,抗冻性良好,不易风化;颜色美丽,大多为淡灰或肉红色,也有呈深青和黑色的。缺点是耐高温性能差,在高温下,石英晶型转变,体积膨胀而使石材崩裂。花岗石的用途根据晶粒大小分:晶粒细小的可加以磨光或雕琢,作为装饰板材或艺术品;中等粒度的常用于修筑桥墩、桥拱、堤坝、海港、勒脚、基础、路面等;晶粒粗大的轧制成碎石,是混凝土的优良集料。
  
  由于花岗石耐酸,还用做化工、冶金生产中的耐酸衬料和容器。
  
  中国的花岗石资源丰富,品种繁多,自古在土木工程中大量采用。作为饰面石材的就有济南青等40余种,主要产地为:山东的泰山、崂山,陕西的华山,北京的西山以及福建南部等。(见彩图)
