摘要
本文以珲春早第三纪含煤盆地的地质构违背景为依据,分析了煤系地层的岩石学特征。认为该盆地早第三系的火山碎屑岩系主要来自盆地周围中生代火山岩和火山碎屑岩,绝大部分属于二次沉积的产物。文章对现行的火山碎屑岩分类命名中存在的问题进行了探讨。
This paper discusses the petrologic characteristics of the coal-bearing strata under the geologic structural background of the Tertiary coal basin in Hunchun. The author thinks that Paleogene voleaniclastic rock of the basin is mainly derved from the Mesozoic volcanic rock and voleaniclastic rock surround the basin and belongs to the products of secondary deposition. It also discusses the problems that exist in the current classification and marne of volcaniclastic rock
