煤植体分类初探

煤植体研究是从其植物来源上研究煤的组成，提高对煤本质特征的认识，因此，近年来在煤地质研究领域中已逐渐发展成为一个独立的分支。煤植体分类是煤植体研究的基础。本文以笔者对内蒙古霍林河煤田晚中生代褐煤煤植体研究为基础，并结合前人研究的有关资料，就煤植体的分类进行了初步探讨。以既能反映煤植体的植物学特征又能体现其破碎和发生煤化的特点为分类原则，据此将煤植体分为不同的大类（依据原植物的器官划分）、类（依据原植物的组织划分）和亚类（依据保存类型和降解程度划分），并对具体的分类方案和命名方法进行了讨论。

PRELIMINARY CLASSIFICATION OF PHYTERALS

The aim of the research is to study the compositions of coal from the source of plant, to improve our knowledge of coal properties. In the recent years,it has gradually become a branch of coal geological research. Classification of phyterals is the basis of the research. In this paper the authors propose a preliminary classification system based on the investigation of lignite phyterals of Late Mesozoic Age in Huolinhe Coalfield in inner Mongolia and based on the relevant data collected by other researchers. The principles of phyterals classification represent not only the botanical features, but also characteristics of fracture and coalification. Phyterals are divided into supergroups based on organs of plants,groups based on tissues of plants and sub-groups based on types of preservation and degree of degradation. A specific classification proposal and nomenclature are discussed.
