Five typical coals of low-to-medium rank (Huolinhe brown coal, Majiata non-caking coal, Datong weakly caking coal, Huozhou gas coal, Lingshi fat coal) and their macerals are prepared. The molecular structure and the oxygen functional groups of the selected coals and their macerals are studied by means of the conventional coal properties analysis, chemical analysis and the advanced instrumental methods such as FTIR,XRIK 13C-NMR.N XPS. The molecular structure characteristics, regularities and the results are discussed. Additionally, the total oxygen content and distribution characteristics of different oxygen functional groups in the raw coals and their macerals are studied.

本文中选取了中低变质程度煤中的五种典型煤种——霍林河褐煤、马家塔不粘煤、大同弱粘煤、霍州气煤、灵石肥煤以及它们的不同显微组分作为研究对象，采用了常规的煤质分析、化学分析法以及先进的仪器分析法如傅立叶变换红外光谱、X射线衍射、高分辨固体~(13)C核磁共振谱~(13C-NMR及X光电子能谱等方法，全面地研究分析了所选煤样的惰质组、镜质组的分子结构及煤中氧的赋存形态，得到所选煤样惰质组分的分子结构特征及结构参数，分析比较了惰质组与镜质组在分子结构上的差异性，并讨论了惰质组分的分子结构特征及结构参数随煤变质程度的变化规律；同时，通过研究得到了所选原煤样及其显微组分中总氧含量及各种不同类型含氧官能团的含量分布特征。

Based on the a series of research carried in typical gold lodes in Linglong, Jiapigou, Dongfeng and Xiaoqinling and related data, it is suggested that the deposit type is concentrated in the circumference of the North China Platform, occurring in the Archean granite-greenstone belts, being adjacent to deep-cut faults and being accompanied by the Mesozoic, remelted l-type granites. The spatial distribution features of the deposit type indicate that the deposits are closely related to the multiple evolution of the mantle plumes.

通过对玲珑、夹皮沟、东风和小秦岭等典型中深脉状金矿及相关资料的研究表明：中深脉状金矿主要分布于华北地台的周边，位于太古代花岗—绿岩带中，与深大断裂相邻，同中生代重熔I型花岗岩伴生，这种空间展布特征与地幔的多级演化有关。
