补充资料:火成碎屑岩
火成碎屑岩
pyroclastic rock

   由火山碎屑物质堆积而成的岩石。又称火山碎屑岩。其特征介于熔岩与正常沉积岩之间。火山碎屑物的含量一般大于50%,其次为正常沉积物或熔岩物质。碎屑物的种类有岩屑、晶屑、玻屑、火山弹、浮岩及火山渣等。碎屑物的大小不一,常见棱角状。具集块结构、火山角砾结构、凝灰结构、火山尘结构等和假流纹状、斑杂状、火山泥球状、层理状等构造。分为两大类型:①熔结火山碎屑岩。由火山碎屑物经熔结而成。通常火山碎屑物含量大于90%。包括熔结集块岩、熔结角砾岩、熔结凝灰集块岩和熔结凝灰岩等。②正常火山碎屑岩。由火山碎屑物质经一定的压实作用形成。包括集块岩、火山角砾岩、火山凝灰角砾岩和凝灰岩等。其中凝灰岩分布最广。此外,火山碎屑岩与熔岩和正常沉积岩之间还存在一系列过渡类型。广义上,含火山碎屑物质大于10%的岩石都可称作火山碎屑岩。与火山碎屑岩有关的矿产有各种金属和非金属矿产(如Fe、Cu、Pb、Zn、S、B等)。如中国甘肃的白银厂铜矿床、镜铁山铁矿床等。
