| 中文摘要: |
| 本文通过对赫章 15个方解石矿体进行地质调查及取样分析，研究方解石矿床地质特征、控矿因素、成因 及分析成矿远景。发现 15个矿体规模大小不一，呈分散状分布，矿石成分单一，矿体以脉状为主，透镜状次之。通过样品分析评价，整体矿石质量较好。矿体受地层岩性和断裂构造的控制，有利地层以二叠系 栖霞至茅口组灰岩为主，石炭系黄龙组灰岩、白云质灰岩次之，有利控矿构造以 NE、 NW向的逆断层为 主。根据地质特征分析，认为方解石矿体属于低温热液充填型。通过综合分析认为，松林坡、兴发、白果、威奢一带具有良好的找矿远景。 |

| Through geological survey and samping analysis on 15 calcite ore bodies in Hezhang County, Guizhou,this paper studied the geological characteristics,ore-controlling factors,genesis and prospects of calcite deposits there 15 ore bodies were found with di erent sizes,dispersed distribution and single ore composition The ore bodies mainly are vein-shaped,secondly are lenticular Through sample analysis and evaluation,it was found that the overall ore quality is good The ore bodies are controlled by stratum lithology and fault structures The favorable stratum is limestone of the Permian Qixia-Maokou formation,followed by the limestone of Carboniferous Huanglong formation and dolomitic limestone The favorable ore-controlling structures are dominated by NE/NW direction reverse faults According to the analysis on geological characteristics of the calcite ore bodies,the genesis of the calcite ore bodies is considered as low-temperaturehydrothermal llingtype Through comprehensive analysis,this paper concluded that Songlinpo,Xingfa,Baiguo,and Weishe are good prospecting areas |
