| 中文摘要: |
| 河南石墨矿床分布具有明显的区域性分带特征，从南至北划分了南带、中带、北带3个石墨成矿带。研究区位于石墨中矿带的东端，在约185 km2范围内已发现石墨矿床（点）7处，其中大型1处，中型1处，小型2处，矿点3处。为了进一步扩大石墨矿找矿成果，本文通过典型石墨矿床剖析，总结本区石墨矿分布特征及成矿规律，并分析石墨矿控矿因素及找矿标志。研究发现，本区石墨矿的形成、分布受区域成矿环境、地层、构造、岩浆岩等因素控制，其中，受地层控制最为显著。区域上石墨矿化普遍，矿化强度高、范围大，区域石墨成矿环境优越，具有良好的石墨找矿潜力。 |

| The distribution of graphite deposits in Henan Province has obvious regional zonation characteristics， from south to north， it is divided into three graphite metallogenic belts： South zone， Middle zone and North zone. The study area is located in the eastern end of the graphite middle ore belt， and 7 graphite deposits （points） have been found in the range of about 185 km2， including 1 large， 1 medium， 2 small and 3 ore points. In order to further expand the results of graphite ore prospecting， this paper summarizes the distribution characteristics and metallogenic rules of graphite ore in this area through the analysis of typical graphite ore deposits， and analyzes the ore-controlling factors and prospecting indicators of graphite ore. It is found that the formation and distribution of graphite deposits in this area are controlled by regional metallogenic environment， strata， structure， magmatic rocks and other factors， among which the stratigraphic control is the most significant. The graphite mineralization in the region is common， the mineralization intensity is high， the range is large， the regional graphite metallogenic environment is superior， and it has a good graphite prospecting potential. |
