The burnt rock is a kind of metamorphic rocks which developed in baking metamorphic country rock by the reason of spontaneous combustion of thick coal seam .

烧变岩是厚煤层自燃，围岩受烘烤变质而形成的一种变质岩。

The paper has reviewed on spontaneous combustion area of coal in magnetic surveying , and carry out inferential interpretation in the baking zone of unmagnetic burnt rock , with geological law and coal burnt law in the area .

本文阐述了磁法探测煤层火区，在没有磁性的烧变岩烘烤带部分，利用该地区的地质规律及煤层烧变的规律进行外推解释。

Its natural types are roasted kaolin , burnt breccia , burnt rock and burnt mudstone .

焙烧高岭土、火烧角砾岩、火烧岩、烧变泥岩四种矿石自然类型。

Its petrology and Fe 2O 3 / ( FeO + Fe 2O 3 ) ratios shows the burnt rocks can be divided into two kinds : burnt rock and melt rock .

从岩石学特征、Fe2O3/（FeO+Fe2O3）比例可将烧变岩划分为烧变岩和烧熔岩两种。
