补充资料：碱性岩
| 碱性岩 alkalic rock 火成岩的一种 。二氧化硅含量较低 ，碱质含量较高（Na2O＋K2O＞ Al2O3 ） 。一般呈浅灰 、浅绿或浅红色。主要浅色矿物为碱性长石（微斜长石、正长石、钠长石），暗色矿物为霓石、霓辉石、钠铁闪石、钠闪石等，副矿物有方钠石、锐钛矿和磷灰石等。可分为深成碱性岩，如霞石正长岩；浅成碱性岩，如霞石正长斑岩；喷出碱性岩，如响岩等。一般产在地壳构造运动较弱的稳定地区，很少形成独立岩体，多与基性岩、超基性岩、碱性正长岩、碳酸岩一起形成杂岩体。与之有关的矿产有铌、锆、稀土、铁、钛、磷等。可利用其钾含量高、二氧化硅含量低的特点，制作化肥和陶瓷原料。 |
