摘　　要：为探讨湖南渣滓溪锑矿床的矿体空间分布和矿化富集特征,通过深入分析矿床勘查的最新成果,首次提出渣滓溪“薄脉型矿床深部存在厚大矿体”的新观点。还对矿体空间分布特征进行了详细分析,对矿化富集特征展开了综合评估。研究结果表明,渣滓溪锑矿床的矿体分布和富集与F_(3)断裂密切相关,矿脉数量和矿化强度随着与F_(3)断裂的接近而增加。矿化富集程度与地层及岩性组合密切相关,且锑矿化强度呈现“弱→强→弱”的垂向变化趋势。结论指出,渣滓溪锑矿床是一个典型的薄脉形锑矿床,其矿体分布、富集受构造和地层的联合控制,为矿床的勘查开发提供了科学依据。To investigate the spatial distribution and mineralization enrichment characteristics of the antimony ore bodies in the Zhazixi antimony deposit,Hunan,this study presents a new perspective that“thick and large ore bodies exist at depth in the thin-vein type deposit”based on an in-depth analysis of the latest exploration results.A detailed analysis of the spatial distribution characteristics of the ore bodies and a comprehensive assessment of the mineralization enrichment features have been conducted.The results indicate that the distribution and enrichment of the antimony ore bodies in the Zhazixi deposit are closely related to the F_(3)Fault,with an increase in the number of ore veins and the intensity of mineralization approaching the F_(3)Fault.The degree of mineralization enrichment is closely related to the stratigraphy and lithological combinations,and the intensity of antimony mineralization shows a vertical variation pattern of“weak→strong→weak”.The conclusion suggests that the Zhazixi antimony deposit is a typical thin-vein type antimony deposit,with its ore body distribution and enrichment controlled by the combination of structure and stratigraphy,providing a scientific basis for the exploration and development of the deposit.
